Exact frequency
Enter any supported frequency directly rather than being limited to the preset buttons. Presets simply provide quick starting points for commonly useful values.
This test tone WAV generator creates a fixed-frequency audio signal directly in your browser. Choose the frequency, waveform, duration, level and WAV format, preview the tone, then save the generated file. Return to Ronter Sound or explore more Audio Tools for Musicians.
Set a fixed frequency and create a clean test signal with your chosen waveform, duration, level, channel format and sample rate.
Choose the signal you want to hear and save as a WAV file.
A test tone is a steady periodic signal at a selected frequency. Enter a value in hertz or choose one of the frequency presets, then select the waveform, level and duration. Play Tone lets you hear the signal immediately before creating a file.
Unlike a frequency sweep, the fundamental frequency does not travel from one value to another. A 1 kHz test tone remains at 1 kHz for the chosen duration. This makes a fixed tone useful when you want one stable reference signal rather than a changing frequency.

Frequency defines the pitch of the generated signal, while waveform, level, duration and file format determine its shape and how the WAV is stored.
Enter any supported frequency directly rather than being limited to the preset buttons. Presets simply provide quick starting points for commonly useful values.
Generate a sine, triangle, square or sawtooth signal. Each uses the same selected fundamental frequency but has a different waveform shape and harmonic content.
Choose mono or stereo and select a WAV sample rate. The downloaded file is created as uncompressed PCM audio using the current generator settings.
A test tone WAV generator gives you a repeatable audio signal whose frequency and level are known before the file is created. Instead of searching for a prerecorded tone, you can enter the values you need, preview the result and generate a fresh WAV.
This can be convenient for basic signal experiments, learning, playback checks and situations where a simple reference file is easier to work with than music or speech.
Frequency is measured in hertz. Increasing the frequency produces a higher-pitched tone, while decreasing it produces a lower-pitched tone. The numeric field lets you choose the value directly from the supported range.
Preset buttons such as 100 Hz, 440 Hz and 1 kHz are shortcuts only. You are free to type another value when your test requires a different frequency.
A sine wave is the simplest waveform offered by the generator. An ideal sine contains one frequency without the harmonic series found in the other waveform options, which makes it a straightforward choice when you want a basic fixed-frequency signal.
Square, sawtooth and triangle waves behave differently because their shapes introduce harmonics. They can therefore sound substantially different even when the fundamental frequency shown by the tool is identical.
The level control determines the amplitude used to create the digital signal. The displayed dBFS value is referenced to the maximum digital level available to the generated PCM waveform.
It does not tell you the acoustic sound-pressure level that will reach your ears. That depends on the playback system, its volume setting and the listening environment. For this reason, it is sensible to begin playback at a conservative listening volume.
In Mono mode, the exported WAV contains one channel. In Stereo mode, the same generated signal is written to both left and right channels. This creates a two-channel file without introducing a difference between the two sides.
If you are learning how channel balance and other mixer controls affect audio, the Mixer Console Simulator provides a different way to experiment with mixing concepts.
The generator offers 44.1 kHz, 48 kHz and 96 kHz PCM WAV output. Sample rate determines how many samples are stored for each second of generated audio.
When the selected test frequency is too close to or above the Nyquist limit for the chosen sample rate, the generator prevents an invalid export and asks you to choose a suitable combination.
Starting or stopping a waveform abruptly can create a discontinuity at the boundary of the file. The optional short edge fade gradually raises the signal from silence at the beginning and returns it to silence at the end.
If you specifically need the generated waveform to begin at full amplitude with no fade, choose None. Otherwise, a short fade can make starting and stopping the test tone less abrupt.
Music and recorded instruments change constantly. Their amplitude, pitch, harmonic balance and dynamics evolve from moment to moment. A fixed test tone removes much of that complexity and gives you a deliberately simple signal.
When you move from generated signals to real instruments, the interaction between fundamentals, harmonics and performance becomes much richer. You can explore that practical side through Instrument Recording and Blues and Country Recording.
A steady signal can help make changes in level or routing easier to notice because the source itself remains consistent. Real mixing, however, involves multiple changing sources, dynamics, stereo placement and tonal decisions.
For those broader subjects, continue with Mixing and Mastering or read about the practical role of an Audio Engineer.
A generated tone is intentionally artificial. It does not reproduce the transient detail of percussion, the changing harmonics of an instrument or the articulation of a singer. That simplicity is what makes it useful as a controlled signal.
When preparing to work with actual musical performances, the First Time Recording Studio Guide provides a broader introduction, while Music Recording covers work with songs, tracks and instruments.
Speech and singing contain continuously changing combinations of fundamental frequencies, harmonics and resonances. A fixed tone should therefore be treated as a reference signal rather than a substitute for real vocal material.

When you press Download WAV, the browser calculates the waveform sample by sample using the selected frequency, duration, level and sample rate. Mono output stores one sample stream; stereo output writes the generated value into both channels.
The file is assembled as PCM WAV and offered for download when generation is complete. Longer durations and higher sample rates contain more samples, so they require more memory and create larger files.
Test signals are useful building blocks for learning and technical experiments, while finished productions involve recording, editing, mixing and many creative decisions. Explore Audio Recording, Mixing & Mastering Services for the wider production process.
For work built around spoken or produced media, see Audio Content Recording Services. Songwriters can also continue with Song Demo Production.
Set the frequency, waveform, level, duration and file format, preview the signal at a comfortable listening volume, then create your WAV.
