A DAW, or digital audio workstation, is a system for arranging, editing, processing and mixing audio. Ronter Sound Lab is a free online DAW that runs in a web browser and combines two ideas that are often separated: a modular signal-processing laboratory and a timeline-based multitrack audio editor. In Single Track you study and design one signal in depth. In Multi Track you arrange many clips, give every track its own processing system, sum them into a Master bus, and render a finished WAV mix.
Use the built-in track or load a local WAV/MP3. SOURCE also holds signal mode, BPM and TIME SYNC.
An FX block that merely sits on the field does nothing. It must lie on a real route from SOURCE to MASTER. One output can feed multiple branches for true parallel processing.
Connect MOD OUT to the yellow target above a knob. The effective value then moves around the knob’s base setting over time.
Stereo processes the combined stereo signal. L/R gives independent channel controls. Mono/Side lets you design the center and side information separately.
Sound Lab can detect BPM or accept a manual value. With TIME SYNC, time-based parameters can use musical divisions from very short values through multiple bars.
MASTER receives the final signal. Use its level information to judge whether creative processing is adding useful energy or simply creating overload.
VIEW changes with the device: EQ/filter response, compressor transfer and gain reduction, delay/reverb tails, stereo image, or the modulation function itself.
Input/output meters reveal where a chain gets louder, quieter or clips. The ACTIVE lamp can turn red on clipping.
RESET returns a device to defaults and clears incoming modulation for that device. Collapse keeps a complex patch readable without deleting anything.
Choose which FX and modulators are allowed, or USE ALL. Randomizer builds a session from that set. Treat the result as a starting point to listen, edit and simplify.
A patch can be saved to a JSON file and loaded later, including device state, cables, modulation connections and layout.
On phones, modules flow downward instead of expanding beyond screen width. The system can warn when DSP/CPU load becomes high enough to risk crackles or dropouts.
The raw audio is the material. In Single Track there is one source. In Multi Track there can be many clips placed at different times on different tracks.
A Multi Track lane owns its clips, Mute/Solo state, volume, pan and an independent processing preset. Moving a clip to another track also changes which track processing it passes through.
FX are nodes in a real signal graph. Series routing changes the sound step by step; parallel branches let clean and processed versions coexist and sum later.
In Multi Track, all audible tracks are summed, then the Master can have its own processing, level and pan before the final WAV render.
Use it when the main question is “What should happen to this one sound?”
Use it when the main question is “How should several sounds live together in time?”
A simple browser audio editor may focus mainly on loading, trimming or processing one file. Single Track covers this focused workflow but adds modular routing, effects and modulation.
Multi Track adds a shared timeline, independent tracks, clip movement, trim, split, copy/paste, Volume, Pan, Mute, Solo and per-track processing.
Ronter Sound Lab combines multitrack editing with modular audio effects, modulation, Master processing, project presets and WAV export without requiring a desktop DAW installation.
Audio is the sound itself. Turquoise cables answer the question: where does the sound go? If an FX block is not on a valid route to MASTER, it does not affect the audible result.
Modulation is not another audio track. It is a moving control value. Yellow/orange cables answer the question: which knob should move, how far, and in what direction?
SOURCE → EQ → COMPRESSOR → REVERB → MASTER. Every stage receives the result of the previous one. Order matters because each processor changes what the next processor hears.
One output can feed more than one branch. A clean branch can go directly to MASTER while another branch goes through Amp, Saturator or Codec. The branches sum later, preserving clarity while adding character.
In Multi Track, all clips placed on one track feed that track’s shared processing and then its Volume/Pan controls. Think of the track as one channel strip with a modular processor inserted before its final level/pan stage.
All audible tracks meet at MASTER. Master Processing affects the combined mix, so a small EQ, compressor, stereo or limiter change can influence every track at once.
Moving, trimming, splitting and copying clips changes how the project refers to audio; it does not rewrite the original source file on disk. The same source audio can therefore be used by several clip segments without making several physical copies of the file.
Many audio decisions become confusing when one version is simply louder than another. Watch IN/OUT meters, track meters and MASTER. When comparing two settings, try to keep perceived loudness reasonably similar. Use output controls and track volume to prevent each stage from making the next stage unnecessarily hot.
The left and right channels move through one stereo processing architecture. This is the simplest mode for ordinary processing.
Left and right can receive different parameter values, bypass states and processing decisions. Useful for asymmetry, repair and extreme stereo design.
Mid/Mono represents common center information; Side represents the left-right difference. This lets you change width and edge information without treating the center the same way.
The browser must calculate every active processor, analyser, modulation connection and track in real time. LATENCY tells you roughly how much audio delay the current audio system introduces. DSP LOAD ~ is an estimate of how demanding the current project is. If the project becomes unstable, simplify unused FX/MOD, bypass heavy chains, close unnecessary browser work, or render a result and continue from audio.
Single Track works as a focused online audio editor and modular audio-effects processor for one source. Use it to understand a sound, build an effects chain, learn audio signal flow, create modulation, compare dry and processed audio, and export one processed WAV result without installing a desktop DAW.
| Control | What it does | How to use it |
|---|---|---|
| LOAD FILE | Replaces the current source with a local audio file. | Choose WAV, MP3 or another browser-decodable audio file. The filename appears under the Ronter Sound Lab title. |
| PLAY / STOP | Starts or stops Single Track playback. | The same transport can also be toggled with Space when you are not typing into a control. |
| EXPORT WAV | Offline-renders the current Single Track patch to WAV. | Use it after the route and parameter state sound correct. The render follows the processing configuration rather than recording the speaker output in real time. |
| SETUP LATENCY | Displays the approximate audio-system latency. | Useful when judging how responsive the browser feels during interactive work. |
| DSP LOAD ~ | Shows an approximate processing load. | Watch it when adding many FX, modulators, analyzers or complex routing. |
| ACTIVE PATH | Summarizes the current valid audio route. | If there is no complete path from SOURCE to MASTER, a processor may look active but no processed sound can reach the output. |
| LFO LINKS | Counts modulation links. | A quick indication of how many live control relationships are active. |
| Control | Meaning | Use |
|---|---|---|
| FIELD | Changes the virtual processing-field size. | Increase it when a complex patch needs more room for modules and visible cables. |
| ZOOM | Zooms the entire processing field. | Zoom out to understand a large patch; zoom in to patch or read details. |
| UI SIZE | Changes the size of the devices themselves. | Useful when the field contains many processors but you still want readable controls. |
| Click a device | Selects it for close inspection. | The selected device enlarges to roughly 150%. Click empty field space to return it to normal size. |
| RANDOMIZE PRESET | Builds a randomized patch from allowed FX/MOD choices. | Use as an idea generator, not as a promise of a “correct” mix. Listen, simplify and edit afterward. |
The program can begin from the built-in example or a local file loaded with the top LOAD FILE button.
This changes the architecture of the processing graph, not merely the display. Dual modes expose two independent lanes.
AUTO estimates tempo. The numeric BPM field can be typed manually when the detector is wrong or the material has an intentional tempo.
When enabled, supported time/rate parameters can follow musical divisions instead of free milliseconds or Hertz.
Opens the FX palette. Adding a device places it on the field; it still needs a valid audio cable route to affect the sound.
Opens the modulator palette. A modulator does nothing to audio until its output is connected to a modulation target.
| Element | What it means | Important detail |
|---|---|---|
| ACTIVE lamp | Device power/bypass control. | Click it to bypass or reactivate the processor. Bypass is the fastest way to ask “is this block really helping?” |
| RESET | Returns that device to its defaults. | Useful after an extreme experiment. Incoming modulation for that device is also cleared where the current implementation requires it. |
| X | Deletes the device. | Removing a device also changes the patch architecture, so inspect the remaining cables afterward. |
| Collapse tab | Collapses/expands the module. | Use it to keep a large field readable without deleting the processor. |
| VIEW | Opens the device-specific visual monitor. | The window can show EQ/filter response, compression behavior, delay/reverb tails, stereo image, waveform/spectrum or the modulation shape depending on the device. |
| Knob | Changes one parameter. | Drag the control, or click the numeric value under a knob to type an exact value. |
| IN / OUT meters | Show signal level around the processor. | Use them to locate unexpected level jumps, silence or clipping. |
| Audio IN / OUT ports | Carry actual sound. | Turquoise cables define the real audio graph. |
| MOD OUT / yellow target | Carry control movement. | Connect a MOD OUT to a target above a compatible parameter knob. |
| Polarity + / +− / − | Direction of modulation. | Positive moves away from the base value upward, Bipolar moves around it, Negative moves downward from it. |
Drag from an OUT port to an IN port, or start from a compatible port and finish at its counterpart. The turquoise cable is not decoration; it becomes part of the real audio route.
One output can feed more than one destination. For example, SOURCE can go directly to MASTER and also through SATURATOR → MASTER. Both paths are summed.
Move or remove connections when you want a different signal order. After a change, use ACTIVE PATH and the cable animation as a sanity check.
In LEFT/RIGHT or MONO/SIDE mode the graph exposes two colored lanes. Each lane can have different settings, meters and bypass states.
| Control | What it does | Best use |
|---|---|---|
| EQ DEFAULT | Restores the program’s default simple signal route. | Use when experimentation has become confusing and you want a known working starting point. |
| CLEAR PATCH | Removes the current audio and modulation connections. | Use when you want to rebuild routing from zero without reloading the page. |
| ORIGINAL / PROCESSED | Global comparison between bypassed processing and the active patch. | Level-match as much as possible before judging. The button text changes to show which state you can switch to. |
| SAVE PRESET FILE | Saves the Single Track processing patch to a preset file. | Preserves device state, routing, modulation and layout for later reuse. |
| LOAD PRESET FILE | Loads a saved Single Track processing preset. | Use it to recall a sound-design system without rebuilding every block and cable. |
Know the source before processing it. Identify the problem or goal in one sentence.
Stay in STEREO unless you have a specific reason to treat L/R or Mid/Side independently.
Start with one corrective or tonal processor. Add another only when its job is clear.
A stable static chain is easier to judge than a moving chain whose basic tone is already wrong.
Choose one destination and begin with very small depth. Increase only until the desired life or rhythm appears.
Confirm your hearing with visual evidence, but do not chase a “pretty” graph.
Ask whether the processed version actually solves the original problem or creates a stronger artistic identity.
Save the patch if you may want to revisit the system, then render the processed audio to WAV.
Multi Track turns the modular system into a free browser-based multitrack audio editor. Arrange WAV or MP3 clips on a shared timeline, edit and move clips, give every track independent effects and modulation, balance Volume and Pan, process the Master bus, save the project structure, and export the complete mix to WAV.
The actual WAV/MP3 content loaded from the computer. Several clip segments may refer to the same source audio.
A clip has a start time plus trim boundaries. Splitting or copying produces more independently editable clip instances.
All clips on a track feed that track’s own Processing, then its Volume/Pan and finally the Master sum.
| Control | What it does | Important behavior |
|---|---|---|
| + TRACK | Adds another audio track and selects it. | Each track receives its own independent processing preset/state. |
| FIT TIMELINE | Calculates a zoom that fits the current project into the visible timeline area. | Useful after loading long audio or after zooming deeply into a short section. |
| PROJECT 00:30.000 | Displays the current project duration. | The project has a minimum timeline length and expands as clip content extends farther in time. |
| ZOOM | Changes horizontal time scale. | Higher zoom gives more pixels per second for precise clip movement and trimming. |
| Select arrow | Normal clip-selection/move tool. | Use for moving clips horizontally in time or vertically to another track. |
| Scissors | Splits a clip at the clicked position. | The two resulting segments remain non-destructive references to the same source audio. |
| Undo | Reverses the previous timeline edit. | Also available with Ctrl/Cmd + Z. |
| Redo | Restores an undone timeline edit. | Use Ctrl/Cmd + Y or Shift + Ctrl/Cmd + Z. |
| COPY | Copies the currently selected clip segment. | Equivalent to Ctrl/Cmd + C. |
| PASTE | Creates another instance of the copied clip at the current playhead position. | Equivalent to Ctrl/Cmd + V. The new clip can be trimmed, split and moved independently. |
| PLAY / STOP | Starts playback; while playing the same action stops and returns transport to the start. | Space toggles play/stop in Multi Track when focus is not inside an editable field. |
| PAUSE | Stops playback while preserving the current position. | Press PLAY afterward to continue from that position. |
| Clock | Shows the current playhead time. | Format is minutes:seconds.milliseconds. |
| LATENCY | Shows approximate current Multi Track audio latency. | Based on the active Multi Track AudioContext. |
| DSP LOAD ~ | Estimates whole-project processing load. | It considers active processors/modulation plus runtime responsiveness. Treat it as a warning indicator, not laboratory-grade CPU measurement. |
| LOAD PRESET | Loads a saved Multi Track project preset JSON. | The arrangement and processing are restored first; external audio must then be relinked. |
| SAVE PRESET | Saves the whole project structure as JSON. | Stores tracks, clip positions/trims, mix settings, per-track Processing, Master Processing, project position/zoom and audio-file metadata references. |
| Element | What it does | Notes |
|---|---|---|
| Track number / name | Identifies the track and selects its Processing when the strip is clicked. | The loaded audio filename becomes the basis of the track name. |
| M | Mute. | Removes that track from the audible mix. |
| S | Solo. | When any track is soloed, only soloed tracks are audible. |
| X | Deletes the track. | Available when there is more than one track. |
| LOAD AUDIO / REPLACE | Loads audio onto that track or replaces its source clip with another file. | The program decodes the file in the browser. Stereo files retain two channels. |
| VOL | Track output level before the Master sum. | Range extends above unity for deliberate gain. Double-click returns the fader to its default. |
| PAN | Places the track left/right. | −1 is left, 0 center, +1 right. Double-click returns to center. |
| Numeric VOL/PAN fields | Exact entry for mix values. | Useful when matching or repeating a precise balance. |
| L/R meters | Show post-processing track activity. | The thin stereo bars occupy the track edge so they do not cover the faders. |
| Selected-track background | Shows which track owns the visible Processing workspace. | Only the background changes emphasis; controls remain readable. |
Click the ruler or empty timeline lane to move the playhead. During playback the engine reschedules audio from the new position.
With the Select tool, drag a clip left or right. Its project start time changes while the source audio remains untouched.
Drag a clip vertically onto another lane. The clip keeps its own source and trim, but from that moment it passes through the destination track’s Processing and mix controls.
Drag the left or right clip handle. Trimming changes the visible/audible range of the source without deleting source audio.
Choose Scissors and click inside a clip. The clip becomes two segments that can be moved, trimmed, copied and processed according to their destination track.
Select a clip, Copy it, move the playhead and Paste. The pasted clip reuses the same decoded source buffer rather than duplicating the full audio data.
A mono file is drawn as one bipolar waveform. A stereo file is shown as two bipolar channels in one clip: L in the upper half and R in the lower half. The waveform is a visual navigation aid; the actual audio engine still works from the decoded samples.
Click its control strip or lane. The header changes to PROCESSING — TRACK N and that track’s FX/MOD/cables are loaded into the shared editor.
Add FX, add MOD, move devices, patch cables, use Stereo/L-R/M-S, VIEW, meters, bypass, reset and modulation. The same processing vocabulary applies.
Before the editor changes to another channel, the current Processing state is saved back to the track. The newly selected track then restores its own state.
Solo when you need diagnosis, then return to the full mix. A track setting that sounds impressive alone may be too large, bright or wide in the arrangement.
| Element | What it does | Why it matters |
|---|---|---|
| MASTER BUS | Represents the sum of all audible tracks. | Every non-muted/eligible solo track reaches this stage after its own processing and VOL/PAN. |
| M | Mutes the Master output. | Useful as a hard output check. |
| Stereo meter | Shows final left/right mix activity. | Watch for imbalance or excessive level. |
| VOL | Final Master gain. | Use conservatively; it does not replace correct track balance. |
| PAN | Final Master pan. | Normally centered unless a deliberate effect is required. |
| CLICK MASTER TO EDIT ITS PROCESSING | Selects MASTER in the shared Processing workspace. | Master Processing acts on the already summed mix, so changes affect the entire project. |
| EXPORT WAV | Renders the complete project. | Per-track processing is rendered first, track volume/pan is applied, tracks are summed, then Master Processing and Master level/pan are applied to the final WAV. |
A Multi Track project preset is not an audio archive. It is a JSON description of the project. Browser security does not expose a reliable original full path such as C:\Music\song.wav, so the preset stores available metadata — filename, size, modification time, duration, sample rate, channel count and relative path when the browser supplies one.
| Shortcut | Action | Mode |
|---|---|---|
| Space | Play/Stop transport. | Single Track and Multi Track, unless focus is inside an editable field. |
| Esc | Return to Select tool in Multi Track; also cancels certain active patch/mod operations in Processing. | Context dependent. |
| Ctrl/Cmd + C | Copy selected clip. | Multi Track. |
| Ctrl/Cmd + V | Paste copied clip at playhead. | Multi Track. |
| Ctrl/Cmd + Z | Undo timeline edit. | Multi Track. |
| Ctrl/Cmd + Y | Redo timeline edit. | Multi Track. |
| Shift + Ctrl/Cmd + Z | Alternative Redo shortcut. | Multi Track. |
Create tracks, load files and name the arrangement naturally through the files you use.
Move, trim, split and copy clips until the arrangement itself makes sense.
Use track VOL, PAN, Mute and Solo to create a rough mix before adding large FX chains.
Select it and use the shared Processing field. Solve obvious tone/dynamics problems, then add character and space.
Do not make every track huge. Use filtering, width and dynamics so parts occupy different spaces.
Master EQ/compression/stereo/limiting should refine the sum, not rescue a mix whose track balance is wrong.
Save before major experiments and again before final export. Keep source audio organized for later relinking.
Render WAV, then check the file on ordinary speakers/headphones. Return to the project only for changes you can describe clearly.
This is the quick-reference manual for the controls in the free online DAW. The earlier chapters explain workflow; this section answers “what does this exact button, meter, tool or field do?” For every individual audio-effect knob and modulation parameter, use the encyclopedia chapters that follow.

This audio-effects guide explains every processor available in Ronter Sound Lab. Learn what EQ, compression, reverb, delay, saturation, pitch, stereo processing and creative effects do, what each control changes, what to listen for, and when an effect is useful in a real signal chain.
Shape the input before the rest of the chain: level, saturation, warmth, low-end cleanup and air.
PREAMP behaves like the front end of a recording chain. It changes how hard the following processors are driven, adds gentle non-linearity and lets you establish the basic tonal attitude before dynamics and space effects.
Use it when the source feels flat, cold or poorly balanced before compression. It is especially useful when you want the following FX to react to a more intentional input character.
| Parameter | Range | What it changes |
|---|---|---|
| GAIN | 0.20–2.80x | Input level into the processor. More gain usually drives the coloration harder. |
| DRIVE | 0–90% | Amount of harmonic saturation. |
| HPF | 20–500 Hz | Removes low-frequency content below the selected area. |
| AIR | −12…+12 dB | Adds or removes upper-frequency openness and presence. |
| WARM | −12…+12 dB | Changes low and low-mid warmth. |
| OUT | 0.30–1.80x | Output level after processing. |
High GAIN plus high DRIVE can turn warmth into harshness very quickly.
Dynamically controls sharp “s”, “sh”, “t” and other piercing high-frequency bursts.
DE-ESSER watches a selected high-frequency region and reduces it more strongly only when that region becomes excessive.
Use it when the vocal is generally good but individual consonants are painful. Dynamic control is usually more natural than permanently cutting the entire top end with EQ.
| Parameter | Range | What it changes |
|---|---|---|
| FREQ | 2.5–12 kHz | Center of the region where sibilance is detected. |
| CUT | 0–18 dB | Maximum amount of attenuation. |
| THR | −60…−4 dB | Level above which de-essing begins. |
| RATIO | 1:1–20:1 | How aggressively the detector increases attenuation above threshold. |
| ATT | 1–80 ms | How quickly the processor catches a sibilant burst. |
| REL | 30–700 ms | How quickly it recovers afterward. |
Too much de-essing makes speech dull or lispy and can remove useful clarity.
The main tonal sculptor: low shelf, parametric mid band and high shelf.
EQ changes the balance of frequencies. LOW shapes the low shelf, MID is a tunable parametric band with adjustable frequency and Q, and HIGH shapes the top end.
Use EQ for a specific reason: remove boom, add body, move a voice forward, soften brightness, or make space for another element. Avoid “EQ because EQ is expected.”
| Parameter | Range | What it changes |
|---|---|---|
| LOW F | 45–500 Hz | Frequency around which the low shelf works. |
| LOW | −30…+30 dB | Boost or cut the low shelf. |
| MID F | 180 Hz–9 kHz | Center frequency of the mid band. |
| MID | −30…+30 dB | Boost or cut the mid band. |
| HIGH | −30…+30 dB | Boost or cut the high shelf. |
| Q | 0.25–8 | Width of the mid band. Higher Q means a narrower, more surgical band. |
Large boosts can create harshness and overload. A small cut often sounds more natural than a large boost.
Controls the difference between quiet and loud moments and reshapes the attack of the sound.
The compressor reduces level above the threshold. Ratio controls how strongly it compresses, Attack controls how much of the initial transient passes, and Release controls how quickly gain returns.
Use it for steadier vocals, denser bass, controlled drums and “glue” between elements. At 1:1 the ratio is effectively neutral.
| Parameter | Range | What it changes |
|---|---|---|
| THR | −60…−2 dB | Threshold where compression begins. |
| RATIO | 1:1–20:1 | Compression strength; 1:1 means essentially no compression. |
| ATT | 1–120 ms | How quickly gain reduction reacts to a loud event. |
| REL | 40 ms–1.2 s | How quickly gain returns. |
| KNEE | 0–40 dB | Softness of the transition into compression. |
| MAKE | 0.50–1.80x | Post-compression makeup gain. |
Do not judge compression only by the fact that MAKE made the output louder.
Creates slightly drifting copies of the signal for width, shimmer and ensemble motion.
A short delay is continuously modulated. Small time and pitch differences create width and movement without discrete echoes.
Useful for pads, guitars, background vocals and for making a static source feel more alive.
| Parameter | Range | What it changes |
|---|---|---|
| RATE | 0.05–7 Hz | Speed of the internal modulation. |
| DEPTH | 0–12 ms | Amount of delay-time movement. |
| DELAY | 4–35 ms | Base delay of the chorus voice. |
| FDBK | 0–55% | Amount fed back into the effect. |
| MIX | 0–100% | Dry/wet balance. |
| OUT | 0.40–1.50x | Output level. |
Heavy chorus can blur the center and reduce mono compatibility.
Moves a pattern of phase notches through the spectrum, from subtle breathing to a pronounced swoosh.
The phaser mixes the signal with a phase-shifted version, creating moving cancellations and peaks.
Use it when you want motion without a conventional echo: guitars, synths, pads, transitions and special effects.
| Parameter | Range | What it changes |
|---|---|---|
| RATE | 0.03–5 Hz | Speed of the internal movement. |
| DEPTH | 50–1800 Hz | Width of the frequency motion. |
| CENTER | 180 Hz–3.5 kHz | Center region of the effect. |
| FDBK | 0–72% | Strength and resonance of the phase character. |
| MIX | 0–100% | Amount of processed signal. |
| OUT | 0.40–1.50x | Output level. |
High feedback can strongly exaggerate narrow frequency areas.
Adds harmonics, density and controlled non-linearity.
Saturation changes waveform shape, generating new overtones rather than simply raising level.
Use it when a source feels thin, sterile or does not translate well to small speakers.
| Parameter | Range | What it changes |
|---|---|---|

Saturation can flatten transients and add more upper-frequency energy than expected.
Warmth, gentle softening and subtle speed instability.
TAPE combines saturation, tonal softening and wow — a slow instability in time/pitch.
Use it to soften digital sterility, add cohesion and introduce understated vintage motion.
| Parameter | Range | What it changes |
|---|---|---|
| DRIVE | 0–110% | Tape-style saturation amount. |
| TONE | 1.8–19 kHz | How open or softened the top end remains. |

Too much WARM plus DRIVE can cloud the low mids quickly.
Generates additional upper harmonics and increases the perception of air and detail.
Unlike a simple high shelf, an exciter creates new harmonic energy above a selected region.
Useful for dull vocals, synths or mixes when a normal EQ boost sounds too direct or static.
| Parameter | Range | What it changes |
|---|---|---|

Exciters can emphasize noise, sibilance and harshness as well as useful detail.
Cuts low and high frequencies, adds resonance and can become a major moving sound-design element.
The processor combines high-pass and low-pass filtering. RESO emphasizes the LPF edge, DRIVE adds color, and AIR can restore some upper character.
Use it for cleanup, telephone-like bandwidth, transitions, sweeps and continuously evolving timbre.

High resonance can become very loud near the cutoff and may trigger clipping.
Creates audible repeats and rhythmic or atmospheric echoes.
DELAY stores the signal, plays it later and can feed part of the output back into the delay line. Tone and low-cut shape only the repeats.

| Parameter | Range | What it changes |
|---|---|---|
| TIME | 20–750 ms | Time between the source and each repeat. |
| FDBK | 0–86% | Amount of delayed signal fed back for more repeats. |

High feedback can build energy very quickly. Keep an eye on meters and the master output.
Creates a diffuse tail that places the sound inside an imagined acoustic space.
REVERB generates many dense reflections. SIZE changes the sense of scale, DECAY controls how long energy persists, PRE delays the onset of the reverb, and DAMP/LOWCUT shape the tail.
Use it to create depth, glue, atmosphere or a dramatic long tail. Pre-delay is especially useful for keeping a vocal intelligible while still giving it space.
| Parameter | Range | What it changes |
|---|---|---|
| MIX | 0–100% | Dry/wet balance. |
| SIZE | 0.55–1.85x | Apparent size of the virtual space. |

Long bright reverbs can quickly mask consonants and fill every gap in the arrangement.
Shifts pitch by semitones and cents for harmony, doubling and special effects.
The processor changes pitch while using a time window and crossfading approach to keep the stream continuous. TONE limits the upper character of the shifted layer.
Use it for subtle detuning, octave effects, pseudo-harmonies, widening and experimental pitch motion.
| Parameter | Range | What it changes |
|---|---|---|
| SEMI | −12…+12 st | Coarse pitch shift in semitones. |
| FINE | −100…+100 ct | Fine detune in cents. |

| TONE | 1–20 kHz | Upper tonal limit of the shifted layer. |
| OUT | 0.30–1.50x | Output level. |
Large shifts are intentionally more effect-like and can introduce artifacts depending on the source.
Amp and cabinet style coloration for anything from edge and density to obvious guitar-like distortion.
GAIN drives a non-linear stage, the tone stack shapes bass/mid/treble/presence, and CAB changes the broad speaker-style response.
Useful not only for guitar. Vocals, synths, drums and parallel buses can gain attitude, midrange focus and a smaller “speaker” perspective.
| Parameter | Range | What it changes |
|---|---|---|
| GAIN | 0–100% | How hard the virtual amplifier is driven. |
| BASS | −12…+12 dB | Low-frequency tone control. |

At full MIX and high gain, the frequency balance can change radically.
A measurement device: it does not intentionally color the sound.
The analyzer displays the spectral distribution and time-domain waveform of the signal passing through it.
Use it to test a hypothesis: where is the energy, did processing add excessive low end, did a transient become softer, did a filter move where you expected?
| Parameter | Range | What it changes |
|---|---|---|
| DISPLAY | No main audio controls | This is an observation device. Its value is visual feedback rather than signal alteration. |
A graph does not replace listening. A good sound does not need to look “pretty.”
Controls width, balance, Mid/Side energy and low-frequency mono compatibility.
This spatial utility combines basic widening/pan/air with a Mid/Side matrix. Mono Maker can collapse low frequencies toward the center below a chosen frequency.
Use it when you want a wider atmosphere, a stronger center, controlled side energy or a more deliberate M/S image.

| MID PAN | L…C…R | Placement of Mid. |
| SIDE PAN | L…C…R | Placement of Side. |
| MONO < | 40–600 Hz | Mono Maker frequency below which low end is centered. |
Excessive WIDTH or Side energy can make the sound weaker in mono.
The final safety barrier for peaks and output level.
A limiter reduces peaks aggressively near the chosen ceiling and helps prevent the final output from exceeding the desired maximum.
Useful at the end of creative chains, especially when feedback or modulation occasionally produces unpredictable spikes.
| Parameter | Range | What it changes |
|---|---|---|
| THR | −24…−0.2 dB | Level where limiting begins. |
| KNEE | 0–24 dB | Softness of the transition into limiting. |
| ATT | 1–60 ms | How quickly peaks are caught. |

| MAKE | 0.50–1.50x | Additional gain after limiting. |
| CEIL | 0.35–1.00 | Maximum output ceiling in linear scale. |
Constant heavy limiting removes transient punch and musical movement.
Fast chromatic pitch correction with an intentionally obvious hard-tune option.
The detector estimates the current pitch and pulls it toward the nearest chromatic note. The display shows the detected frequency/note and deviation.
Use it for robotic vocal character, hard correction or as a first stage before more extreme vocoder processing.
| Parameter | Range | What it changes |
|---|---|---|
| RETUNE | 2–250 ms | How quickly pitch is pulled to the note. |
| AMOUNT | 0–100% | Strength of correction. |

| TONE | 1.8–20 kHz | Upper tonal limit. |
| MIX | 0–100% | Amount of tuned signal. |
| OUT | 0.30–1.50x | Output level. |
This is chromatic correction, not automatic knowledge of the song key; the musical result depends on the original melody.
A vocoder-like processor that uses the incoming signal itself to build a spectrally modulated output.
The signal is analyzed in bands and resynthesized using SELF, ROBOT, WHISPER or FORMANT-style algorithms.
Use it for robotic voices, whisper textures, formant-like movement and layered vocal sound design without an external carrier.
| Parameter | Range | What it changes |
|---|---|---|
| ALGO | SELF / ROBOT / WHISPER / FORMANT | Chooses the resynthesis character. |
| BANDS | 4–16 | Number of analysis/resynthesis bands. |
| SHIFT | −24…+24 st | Shifts spectral/pitch character. |

| DRIVE | 0–100% | Additional saturation. |
| MIX | 0–100% | Amount of vocoded signal. |
| OUT | 0.20–1.60x | Output level. |
More bands usually preserve articulation; fewer bands create a rougher synthetic character.
Intentionally reduces digital resolution and sample-rate quality.
BITS reduces amplitude resolution, SAMPLE reduces the effective update rate, and JITTER/DITHER add instability and noise-like texture.
Use it for retro game textures, glitch, digital grit and transition effects.
| Parameter | Range | What it changes |
|---|---|---|
| BITS | 2–16 bit | Amplitude resolution. |
| SAMPLE | 800 Hz–48 kHz | Effective sample rate of the effect. |
| JITTER | 0–100% | Timing instability of the sampling process. |
| DITHER | 0–100% | Added noise-like decorrelation. |
| MIX | 0–100% | Amount of degraded signal. |
| OUT | 0.20–1.60x | Output level. |
Very low SAMPLE settings create strong aliasing. Treat that as a deliberate effect, not as “improvement.”
Turns amplitude into a rhythmic envelope: pump, chop, pulse or bounce.
RHYTHMIZER is a purpose-built rhythmic level shaper. Unlike placing an LFO on a random knob, it is designed specifically for musical amplitude motion.
Use it to make a static pad, vocal layer or texture participate in the groove quickly.
| Parameter | Range | What it changes |
|---|---|---|
| RATE | 0.15–16 Hz | Speed of the rhythmic cycle. |
| DEPTH | 0–100% | Strength of the amplitude movement. |

| OUT | 0.20–1.60x | Output level. |
100% depth with sharp algorithms can destroy phrase intelligibility.
Reduces quiet sections and increases contrast between sound and silence.
When level falls below threshold, the processor reduces it according to Ratio and Range. Attack, Hold and Release shape the opening and closing behavior.
Use it for cleaning pauses, drum gating, tighter rhythmic envelopes and deliberately chopped textures.
| Parameter | Range | What it changes |
|---|---|---|
| THR | −72…−3 dB | Threshold for opening/expansion. |
| RATIO | 1:1–12:1 | Strength of expansion. |

| KNEE | 0–24 dB | Softness of the transition. |
| OUT | 0.20–2.00x | Output level. |
A threshold that is too high can cut off quiet word endings and note tails.
Simulates bandwidth loss and artifact patterns associated with low-quality digital transmission.
This is a real-time degradation model, not literal offline encoding. It combines bandwidth restriction, reduced bit depth/sample rate, pre-echo, noise and codec-like artifacts.
Use it for phone, old stream, voice-message, low-bandwidth radio and digital transition effects.
| Parameter | Range | What it changes |
|---|---|---|
| FORMAT | GSM / MP3 LOW / MP3 HQ / AMR | Base character profile. |
| QUALITY | 0–100% | Overall quality amount. |
| BITS | 3–16 bit | Quantization depth. |
| SAMPLE | 4–48 kHz | Sample-rate quality. |
| BAND | 1.2–20 kHz | Available bandwidth. |

| NOISE | 0–100% | Noise layer. |
| MIX | 0–100% | Amount of degraded signal. |
| OUT | 0.20–1.60x | Output level. |
Several degraders in series can quickly collapse into noise and unintelligibility.
Audio effects define the state of the sound; modulation defines how that state changes over time. Learn how an LFO changes effect parameters, how an Envelope reacts to the source, how a Step Pattern creates rhythmic control, and how Math LFO builds more complex repeatable movement.
A repeating control signal for cyclic motion.
The LFO produces a repeating shape — Sine, Triangle, Square, Saw or Random — and uses it to move a connected parameter over time.
Use it when you want continuous periodic motion: filter sweeps, slow width drift, pulsing effect amount, repeated tonal movement or tremolo-like behavior.
| Parameter | Range | What it changes |
|---|---|---|
| RATE | 0.02–20 Hz | Speed of the cycle. |
| DEPTH | 0–100% | How far the destination moves from its base setting. |
| PHASE | 0–360° | Starting position inside the cycle. |
| SHAPE | SINE / TRI / SQUARE / SAW / RANDOM | Geometry of the motion. |
| SLOPE | −95…+95% | Skews the timing/shape of the movement. |
| DUTY | 5–95% | On/off proportion for pulse-like shapes. |
| SMOOTH | 0–100% | Rounds abrupt changes, especially useful for Random or Square. |
Large depth at a fast rate often sounds like a special effect rather than natural movement.
Turns the dynamics of the audio itself into a control signal.
The detector listens only to the frequency band between LOW CUT and HIGH CUT, measures its level, and shapes the response with an ADSR-like envelope.
Use it when an effect should react to the performance instead of repeating mechanically: reverb ducking, drive that increases on attacks, brightness that opens on strong notes.
| Parameter | Range | What it changes |
|---|---|---|
| LOW CUT | 20 Hz–8 kHz | Lower boundary of the detector band. |
| HIGH CUT | 120 Hz–20 kHz | Upper boundary of the detector band. |
| SENS | −72…−6 dB | Sensitivity threshold of the detector. |
| AMOUNT | 0–100% | Strength of the generated modulation. |
| ATTACK | 1 ms–2 s | How quickly the envelope rises. |
| DECAY | 5 ms–3 s | Initial fall after the peak. |
| SUSTAIN | 0–100% | Held envelope level while energy remains. |
| RELEASE | 10 ms–5 s | How slowly modulation returns after the signal falls. |
If sensitivity is too high or timing too fast, the destination can chatter instead of moving musically.
Creates a repeating sequence of discrete modulation levels.
A pattern of 4, 8, 16 or 32 values advances at the selected rate. It can be generated as ascending, descending, up/down or random and regenerated whenever you want a new contour.
Use it for rhythmic filter motion, stepped pitch, changing delay mix, codec quality jumps and structured glitch.
| Parameter | Range | What it changes |
|---|---|---|
| STEP RATE | 0.1–24 Hz | Speed of step advancement. |
| DEPTH | 0–100% | Strength of modulation. |
| SMOOTH | 0–100% | Crossfades between steps instead of jumping instantly. |
| OFFSET | −100…+100% | Moves the whole pattern upward or downward. |
| LENGTH | 4 / 8 / 16 / 32 | Number of steps in the pattern. |
| ALGORITHM | ASCENDING / DESCENDING / UP-DOWN / RANDOM | How values are generated. |
| REGENERATE | — | Builds a fresh pattern using the chosen algorithm. |
A random pattern at full depth can become chaotic quickly. Start shallow and increase only when the effect needs to be obvious.
A programmable LFO whose shape is defined by a mathematical expression.
The expression can use time/phase variables and math functions to build shapes more complex than a standard oscillator. Presets provide useful starting contours such as Sine, Triangle, FM wobble, Heartbeat, Random Hold and polyrhythmic motion.
Use it when a standard LFO feels too predictable and you want repeatable but more sophisticated movement.
| Parameter | Range | What it changes |
|---|---|---|
| RATE | 0.01–20 Hz | Base speed of the function. |
| DEPTH | 0–100% | Amount of modulation. |
| PHASE | 0–360° | Starting phase. |
| X SCALE | 0.1–4x | Stretches or compresses the function along time. |
| OFFSET | −100…+100% | Moves the function upward or downward. |
| SMOOTH | 0–100% | Smooths rapid changes. |
| FORMULA | t, p + math functions | Custom expression defining the movement. |
| PRESETS | 18 shapes | Ready-made formulas for common and experimental contours. |
Complicated formulas are not automatically more musical. The destination, depth and rate matter more than mathematical complexity.
The important skill in modular sound design is not memorizing every processor. Learn to think in audio signal flow: decide what needs to change, choose a useful effect, place it in the right serial or parallel route, then add modulation only when movement has a clear musical purpose.
Describe the problem or artistic goal in one sentence: “the vocal is sharp on consonants,” “the pad is static,” “the echo masks words,” or “the bass disappears on a phone.” A clear sentence immediately reduces the number of tools you need.
Get a convincing tone using ordinary FX before adding modulation. If the static sound is weak, modulation will only make the weak sound move.
Good first modulation targets are MIX, filter cutoff, Side Gain, reverb size/mix, delay mix/time, saturation drive and tonal parameters. Do not modulate every control at once.
LFO = cyclic motion. Envelope = reacts to the performance. Step Pattern = rhythmic sequence. Math LFO = complex repeatable contour.
Increase DEPTH slowly until the sound stops feeling static. The useful point is often much lower than the point where the modulation becomes an obvious special effect.
The same depth at 0.1 Hz and 8 Hz is a completely different artistic gesture. Think in terms of seconds, beats, phrases and sections.
A reverb or delay can sound beautiful solo but cover words in the full mix. Distortion may sound ugly alone yet perfect inside a dense arrangement.
A strong complex patch often uses one slow “scene” movement plus one reactive or rhythmic movement — not four unrelated oscillators.
Keep a clean branch and blend a processed branch into MASTER. This is often better than lowering MIX inside an effect when you want to preserve transients and intelligibility.
After finding something exciting, bypass or remove one processor at a time. If removing a block changes nothing important, the block probably does not need to be there.
EQ, Filter, Exciter and Stereo AIR decide which frequency regions feel close, distant, dark or bright.
Compressor, Gate and Limiter decide how attacks, sustain, loudness and silence behave.
Preamp, Saturator, Tape and Amp add density, edge, warmth and non-linear character.
Chorus, Delay, Reverb and Stereo determine width, depth, echoes and the perceived environment.
Pitch, Hard Auto-Tune and Self Vocoder reshape note identity and vocal/instrument character.
Bitcrusher, Codec Degrader, Rhythmizer and modulation create roughness, rhythm, instability and unusual motion.
One of the most useful techniques is to use one MOD over several seconds to change the “scene,” and another MOD that reacts to rhythm or dynamics. Example: a slow LFO moves Side Gain while Envelope ducks the Reverb quickly.
If an effect is beautiful but destroys attack, split the signal: keep one clean path to MASTER and send another path through Saturator, Amp or Codec. You preserve intelligibility and still gain character.
These practical examples show how to use the free online DAW for vocals, instruments, stereo design, creative effects, multitrack mixing and Master processing. They are not magic presets: use each chain or project layout as a starting architecture, then tune parameters, clip positions, track balance and modulation by ear for the actual material.
| Goal | Chain | Why it works | Modulation idea |
|---|---|---|---|
| Clean modern vocal | DE-ESSER → PARAM EQ → COMPRESSOR → EXCITER → REVERB | Solve the problem first, stabilize dynamics, then add a small amount of clarity and space. | Envelope NEGATIVE → REVERB MIX for automatic space ducking. |
| Warm close vocal | PREAMP → TAPE → COMPRESSOR → REVERB | Color comes before dynamic control; the reverb creates a room without pushing the voice too far back. | Very slow LFO → TAPE WARM or REVERB MIX at minimal depth. |
| Dream vocal | CHORUS → DELAY → REVERB → STEREO | Micro-motion, echoes and a long tail create an evolving wide scene. | Slow LFO → CHORUS MIX; Envelope NEGATIVE → REVERB MIX. |
| Ducked echo vocal | COMPRESSOR → DELAY → REVERB | The dry voice stays intelligible while repeats fill the gaps. | Envelope NEGATIVE → DELAY MIX and/or REVERB MIX. |
| Pulsing pad | FILTER → RHYTHMIZER → CHORUS → REVERB | Tone is shaped first, rhythm is added, then width and ambience enlarge the result. | Step Pattern → FILTER LPF; use TIME SYNC for the rhythmic layer. |
| Living static synth | FILTER → SATURATOR → STEREO | A small tonal drift plus harmonics and width makes a static source feel alive. | LFO 0.05–0.3 Hz → FILTER LPF; second MOD → SIDE G. |
| Lo-fi cassette | TAPE → FILTER → SATURATOR | Speed instability, restricted bandwidth and harmonics produce a cassette-like attitude. | Random LFO with smoothing → TAPE WOW or FILTER LPF. |
| Phone / voice message | CODEC DEGRADER → FILTER → COMPRESSOR | Codec artifacts plus bandwidth restriction create the phone perspective while compression preserves intelligibility. | Step Pattern → CODEC BAND or MIX for changing “connection quality.” |
| Robot vocal | HARD AUTO-TUNE → SELF VOCODER → BITCRUSHER | Pitch is stabilized first, then spectrally transformed and finally given digital texture. | LFO → VOCODER SHIFT or COLOR at shallow depth. |
| Guitar in space | GUITAR AMP → PHASER → DELAY → REVERB | Amp establishes identity, phaser animates tone, delay and reverb create depth. | Slow LFO → PHASER CENTER or DELAY MIX. |
| Parallel dirt layer | SOURCE splits: CLEAN → MASTER and SATURATOR / AMP → MASTER | The clean branch preserves clarity while the dirty branch adds weight and attitude. | Envelope → DRIVE on the dirty branch so distortion follows the attack. |
| Wide but controlled low end | STEREO with MONO MAKER plus modest side shaping | The upper image can widen while low-frequency energy stays centered. | Slow shallow LFO → SIDE G. |
| Rhythmic glitch | BITCRUSHER → FILTER → DELAY | Digital degradation becomes musical when it is organized by rhythm and space. | Step Pattern → SAMPLE or LPF; TIME SYNC → DELAY. |
| Breathing ambience | FILTER → REVERB → STEREO | A long atmosphere changes brightness and width over time instead of sitting still. | Math LFO → FILTER LPF; slow LFO → SIDE G. |
| Dynamic shine | EXCITER → REVERB | Brightness and ambience become stronger only when the source gives the modulator enough energy. | Envelope → EXCITER MIX or AIR; optional negative Envelope → REVERB MIX. |
| Tremolo without a tremolo plugin | Any FX with a usable MIX or output-related target | Level or wet-layer movement can be created with a general modulator. | LFO SINE → MIX/OUT for smooth motion; Square for hard chopping. |
| Stepped pitch design | PITCH → DELAY | Pitch creates discrete notes while delay turns them into musical replies. | Step Pattern → PITCH SEMI; start with low depth. |
| Dense bass | SATURATOR → COMPRESSOR → FILTER | Harmonics improve translation, compression stabilizes the line, and filtering removes unwanted top-end grit. | Envelope → SATURATOR DRIVE very gently. |
The following examples focus on arrangement, independent track processing and Master decisions. They are deliberately architectural: the useful lesson is which stage should solve which problem.
| Scenario | Project architecture | Why it works | Useful move |
|---|---|---|---|
| Lead vocal over stereo instrumental | Track 1: instrumental · Track 2: vocal · MASTER | Keep the instrumental broad and make the vocal intelligible without forcing both through the same corrective chain. | Vocal: De-Esser → EQ → Compressor. MASTER: very gentle Limiter only after balance is stable. |
| Lead + backing vocals | Lead centered · backing tracks panned / widened | The lead owns the center while backing parts create a frame around it. | Use less low-mid energy and more Reverb/Chorus on backing tracks than on the lead. |
| Two guitars fighting each other | Guitar A pan left · Guitar B pan right | Pan creates separation before EQ is forced to solve everything. | Give each guitar a slightly different Amp/EQ character instead of cloning settings. |
| Bass under a wide pad | Bass center · pad wide | Low-frequency focus stays stable while upper information fills the sides. | Pad: Stereo with Mono Maker / side shaping. Bass: Saturator → Compressor, minimal widening. |
| Drum loop + parallel dirt | Original drum track + copied clip moved to a second track | One track preserves attack; the second supplies aggression. | Dirty track: Amp/Saturator/Bitcrusher, then blend with its VOL rather than destroying the clean track. |
| Podcast / dialogue with music | Dialogue track centered · music track lower | Speech gets a dedicated intelligibility chain while music remains musical. | Dialogue: De-Esser → EQ → Compressor. Reduce music VOL before over-compressing speech. |
| Voice-message insert | Duplicate/split vocal phrase to another track | The special effect applies only to the selected phrase without changing the rest of the vocal. | Codec Degrader → Filter → Compressor on the effect track. |
| Robot phrase inside a normal vocal | Split phrase → move segment to new track | Normal vocal and effect vocal can have completely different Processing. | Hard Auto-Tune → Self Vocoder → Bitcrusher on the moved phrase. |
| Dream chorus only | Split chorus clips → move to dedicated chorus track | The verse can stay close while the chorus expands dramatically. | Chorus track: Chorus → Delay → Reverb → Stereo. Keep verse processing simpler. |
| Intro filtered, body full-range | Split intro section → move to second track | One source file can create arrangement contrast without destructive editing. | Intro track: Filter LPF with LFO/Step modulation; body track: normal chain. |
| Call-and-response edit | Copy a phrase and paste later on the timeline | The same performance becomes an arranged response. | Move the pasted clip to a new track and give it Delay/Pitch/Filter processing. |
| Layered sound-design impact | Several short files aligned at the same playhead time | Each layer can specialize: transient, body, sub, texture, tail. | Process each layer for one role, then use Master only for final cohesion. |
| Cinematic rise | Noise/synth/impact tracks arranged toward one event | Independent clip timing lets energy accumulate structurally. | Automated-feeling motion can come from LFO/Step Pattern on filters and Reverb Mix before the hit. |
| Lo-fi breakdown section | Move breakdown clips onto dedicated processed tracks | The effect becomes an arrangement event rather than a permanent master coloration. | Tape → Codec → Filter, then return to clean tracks for the next section. |
| Wide ambience behind a dry lead | Lead dry-ish track + copied ambience/effect track | The center remains articulate while space is controlled independently. | On the ambience track use Reverb/Delay at high wetness and lower VOL. |
| Center-heavy mix with moving sides | Important tracks centered · supporting textures use Stereo processing | The listener gets a stable focus plus motion around it. | Slow LFO → SIDE G on selected supporting tracks, not on every channel. |
| Rhythmic filter on one element only | Keep drums stable; animate synth/pad track | Movement is easier to perceive when another part provides a stationary reference. | Step Pattern → Filter LPF with TIME SYNC. |
| Two versions of the same source | Copy clip, paste, move copy to another track | A/B two processing identities while keeping timing identical. | One track clean/modern; the other Tape/Amp/Codec. Solo between them or blend. |
| Repair left/right imbalance | Use track Processing in LEFT/RIGHT mode | Channel-specific processing can correct or creatively exaggerate asymmetry. | Adjust only the problematic lane rather than globally EQing both channels. |
| M/S control on a stereo stem | Select stem track → MONO/SIDE | Center vocals/bass-like content and side ambience can be treated differently. | Clean low end in Side, or brighten Side slightly while keeping Mid stable. |
| Gentle master glue | Good track balance first → select MASTER | Master processing acts on relationships between all tracks. | Small EQ/Compressor/Limiter moves. If you need extreme Master correction, return to tracks. |
| Creative master transition | MASTER Processing with temporary dramatic effect | A master effect changes the entire scene simultaneously. | Use carefully for sound-design exports; for sectional automation, separate rendered sections may be easier than permanently extreme master settings. |
| CPU-heavy project | Many tracks + many FX/MOD | Complexity grows per channel and on Master. | Watch DSP LOAD ~, bypass unnecessary analyzers/effects, simplify duplicate chains, or render intermediate audio. |
| Project handoff to yourself later | SAVE PRESET + organized audio folder | The JSON preserves project logic while source files stay external. | Keep the preset and audio in one named project folder so RELINK PROJECT AUDIO is quick. |
| Final delivery | All tracks balanced → Master checked → EXPORT WAV | Offline rendering captures track Processing, mix controls and Master Processing in one finished file. | After export, listen to the WAV outside Sound Lab and compare on another playback system. |
Load music on Track 1 and vocal on Track 2. Lower music until words are clear. Process vocal with De-Esser → EQ → Compressor. Add small Reverb. Touch Master only after the two-track balance works.
Copy the vocal clip, paste it, move the copy to a new track. Keep the original clear. On the copy use Saturator or Amp with aggressive settings, then mix the effect track quietly underneath.
Split the vocal or synth at the chorus boundaries. Move chorus segments to a new track. Give the chorus more width, Delay/Reverb or Exciter while keeping the verse intimate.
Pan guitars apart before applying heavy EQ. Give them slightly different midrange or amp characters. The goal is complementary identity, not two individually gigantic sounds.
Center bass and stabilize it with Saturator/Compressor. Put the pad through Filter/Chorus/Stereo and keep low frequencies controlled. Let width live mostly above the bass range.
Stack several clips at one time: transient, low hit, metallic layer, ambience. Process each for a narrow role. If every layer contains full bass and full reverb, the stack becomes cloudy.
Split one phrase, move it to another track and use Codec Degrader + Filter. The rest of the recording stays normal; only that segment becomes a phone/radio moment.
Load pad audio, add Filter and Step Pattern, enable Time Sync, then send Step Pattern to LPF. Add Reverb after the rhythmic movement so the tail smooths the edges.
Use a slow LFO on Stereo SIDE G or another width-related destination. Keep depth small. The movement should feel like the room is breathing, not like the image is collapsing and exploding.
Copy a clip to another track. Leave one clean and heavily degrade the other with Bitcrusher/Codec/Amp. Balance the broken layer quietly to add texture without losing definition.
First mute/solo tracks and fix obvious individual problems. Then select MASTER. Make only the broad decisions that truly belong to the whole mix: small EQ tilt, gentle compression, final stereo check, limiter safety.
Save a Multi Track preset, reload it, locate the requested audio files, then play through the project before relying on it. This confirms both project structure and source relinking before an important final export.
Learn the browser DAW by doing. This practical course moves from a simple Single Track effects chain to modulation, parallel audio routing, multitrack clip editing, independent track processing, mixing, Master processing, project recall and final WAV export.
Keep SOURCE → EQ → MASTER. Move LOW, MID and HIGH one at a time, then explore MID F and Q. Learn to hear “which region moved forward or backward,” not just “better or worse.”
Add Compressor after EQ. Start around Ratio 2:1–4:1, lower Threshold, then isolate Attack and Release. Compare at roughly equal loudness.
Try Preamp, Saturator, Tape and Amp one at a time. Learn the difference between harmonics, warmth, distortion and cabinet coloration.
Compare Chorus, Delay and Reverb. All make the sound feel larger, but by completely different mechanisms: micro-delay motion, repeats and a diffuse tail.
Connect LFO → FILTER LPF. Use very small DEPTH and a slow RATE. Then switch Sine, Triangle, Square, Saw and Random to hear the geometry of movement.
Connect Envelope → REVERB MIX. Try Positive and Negative polarity. Adjust LOW/HIGH CUT and hear the difference between “effect follows loudness” and “effect gets out of the way of loudness.”
Enable TIME SYNC. Connect Step Pattern to FILTER LPF or Delay MIX. Explore 4/8/16 steps and Ascending, Up-Down and Random patterns.
Math LFO → an FX parameter, then use a regular LFO to move a Math/LFO control or vice versa. The goal is two scales of motion, not chaos.
Split SOURCE into a clean branch and a Saturator/Codec/Amp branch, then connect both to MASTER. Compare this with placing the same effect 100% in series.
Choose one artistic sentence — “warm intimate voice,” “broken digital transition,” “wide living ambience.” Use no more than 5 FX and 2 MODs, and be able to explain the role of every block in one sentence.
Load a backing track and one foreground part. Before adding FX, get a believable relationship using only VOL and PAN. This teaches that mixing begins before processing.
Copy a clip, paste it later, split it, trim both sides and move one segment to another track. Then Undo and Redo the edits until the timeline behavior becomes automatic.
Give Track 1 an EQ/Compressor chain and Track 2 a completely different Filter/Delay chain. Switch between tracks and notice that the same visible Processing workspace recalls different states.
Split a section and move it to another track so only that section receives a dramatic effect. This teaches the difference between “change the whole source” and “change one arrangement moment.”
Create a balanced mix first. Then select MASTER and make one very small tonal or dynamic change. Bypass it and decide whether the whole mix truly improved.
Save a Multi Track preset, reload it, then use RELINK PROJECT AUDIO to locate the required files. Understand exactly what lives in JSON and what remains in the external audio files.
Export WAV, open the rendered file in another player, and compare it against live playback. Listen for track balance, Master effects, tails and stereo position.
Use at least three tracks, one clip edit, two different track-processing systems, one tasteful modulation link and a restrained Master chain. Save the project preset and export the final WAV.

Quick answers to common questions about using Ronter Sound Lab as a free browser DAW, multitrack audio editor, modular effects processor and sound-design tool.
An online DAW is a digital audio workstation that runs in a web browser. Instead of relying only on installed desktop software, it provides audio editing, processing, mixing or music-production tools on a web page. Ronter Sound Lab combines a modular Single Track processor with a Multi Track timeline, per-track effects, modulation, Master processing, project presets and WAV export.
Yes. Ronter Sound Lab is a free online DAW. The program on this page can be used as a browser-based audio editor, multitrack mixer, modular effects processor and learning environment without buying the software.
No desktop DAW installation is required to use Ronter Sound Lab itself. The audio engine and interface run in the browser. Your local audio files are selected through the browser and decoded for the current session.
Yes. Multi Track Mode provides a shared timeline with multiple audio tracks. You can load audio, move clips in time, move clips between tracks, trim, split, copy and paste segments, then balance tracks with Volume, Pan, Mute and Solo.
Yes. Ronter Sound Lab can load local WAV and MP3 audio when the browser can decode the file. Single Track uses one source at a time, while Multi Track can use different source files across several tracks and clips.
Yes. Each Multi Track channel keeps an independent Processing state. Selecting a track opens its state in the shared modular Processing workspace, while other tracks continue to use their own saved processing chains during playback and rendering.
The current Sound Lab includes 23 FX/processors covering tone, dynamics, harmonics, pitch, space, stereo processing, analysis and creative degradation. Examples include Parametric EQ, Compressor, De-Esser, Filter, Delay, Reverb, Saturator, Tape, Guitar Amp, Stereo, Limiter, Pitch, Auto-Tune, Vocoder, Bitcrusher, Rhythmizer, Gate/Expander and Codec Degrader.
Modular processing means the effect order is defined by a signal graph rather than a permanently fixed plugin list. In Ronter Sound Lab, turquoise audio cables connect SOURCE, FX and MASTER. You can build serial chains, split a signal into parallel branches, and reconnect processors to study how routing changes the result.
An LFO is a low-frequency control oscillator. It does not need to be heard as a separate audio signal; instead, it moves another parameter over time. In Sound Lab an LFO can animate compatible effect controls, with Rate, Depth, Shape, Phase, polarity and other behavior determining how the destination moves.
Yes. In addition to ordinary Stereo processing, the modular Processing workspace supports independent Left/Right and Mono/Side-style lanes. These modes are useful when the two stereo channels need different treatment or when center information and side information should be processed separately.
Yes. Multi Track project presets save the arrangement and project state as JSON, including tracks, clips, trims, mix settings, per-track Processing and Master Processing. The external audio bytes are not embedded in the JSON, so source files are relinked when the project is reopened.
Yes. Multi Track Export WAV renders the project with per-track processing, track Volume/Pan, the audible track sum, Master Processing and final Master level/pan. Single Track also has its own WAV export for rendering one processed source.
Single Track is best when you want to study or transform one sound in depth with modular effects and modulation. Multi Track is for arranging several sounds on a timeline, editing clips, giving tracks independent processing, mixing them together, processing the Master bus and exporting a complete mix.
Go beyond individual audio tools. Arrange multiple tracks, edit clips, build modular effect chains, add modulation, mix through a Master bus, save projects and export the finished mix to WAV.
