Merge left and right
Standard Mix combines information from both sides instead of simply discarding one channel.
Use this stereo to mono converter online to combine the left and right channels of an audio file into a new mono track. Preview the conversion, choose how the channels are combined, and download the result as WAV. Visit Ronter Sound or browse more Audio Tools for Musicians.
The demo file loads automatically. Replace it with your own audio if you want, select how the left and right channels should be combined, create the mono result, listen to it, and download the new WAV.
Standard Mix combines both channels. Left Only and Right Only are useful when you want one original side to become the mono result.
Stereo audio contains separate left and right channels. A mono file contains one channel. Converting between them therefore means deciding what information from the stereo pair should be written into that single output channel.
With Standard Mix selected, this tool reads corresponding samples from the left and right sides and combines them into one mono stream. The default setting gives both channels equal contribution.
If you want to inspect individual channel behavior before combining sounds, the Interactive Online Audio Mixer provides another way to explore level relationships. The Mixer Console Simulator is useful for experimenting with familiar mixer controls.
A stereo-to-mono conversion can be useful whenever you specifically need one channel of audio rather than separate left and right streams.
Standard Mix combines information from both sides instead of simply discarding one channel.
When one stereo channel contains the material you want, Left Only or Right Only can turn that side directly into mono.
Listen to the generated mono file before downloading it so you can compare the result with the original stereo recording.
A stereo to mono tool online is a focused way to turn a two-channel audio file into a one-channel file. The operation can be simple, but the way the channels are combined matters because stereo recordings do not always contain identical information on the left and right.
A stereo file normally stores one stream of samples for the left channel and another for the right. In the standard conversion used here, the corresponding left and right samples are combined to create each sample of the new mono channel.
With the balance control centered, both sides contribute equally. Moving the control toward Left gives the left channel more influence; moving it toward Right gives more influence to the right channel.
Copying one side and combining both sides are different operations. If musical or spoken material is distributed across the stereo field, choosing only one channel can omit information that exists primarily on the other side.
That is why the converter includes Standard Mix, Left Only, and Right Only as separate choices. For projects involving separately recorded instruments, you can also explore Instrument Recording and Music Recording.
At the default 50/50 position, Standard Mix calculates the mono sample from equal portions of the left and right samples. The level is scaled while the two channels are combined so that simply adding two strong channels together does not automatically double their numerical sample value.
The Output Level control is available separately when you want to change the level of the resulting file. For broader work with finished tracks, see Mixing and Mastering.
Stereo recordings can contain signals whose timing or polarity differs between the left and right channels. When those channels are combined, some parts of the waveform can reinforce one another while others can partially cancel.
For that reason, the mono preview is useful: it lets you hear the actual converted result before saving the file. If you are learning how levels and channels interact, the Interactive Online Audio Mixer offers a complementary hands-on environment.
Sometimes a stereo file was created from two different sources, or useful material exists mainly on one side. In that situation, combining both channels may not be what you want.
Left Only creates the mono file directly from the left samples. Right Only does the same with the right samples. This makes the converter useful for both stereo summing and straightforward one-side extraction.
A one-channel result can also be useful when working with speech, interviews, narration, and other voice material that does not need separate left and right information.

Music often uses stereo placement deliberately, so it is worth listening carefully after conversion. Elements that were spread across the stereo field will now share a single channel, and phase-related differences can become more noticeable.
Musicians preparing recordings can continue with the First Time Recording Studio Guide or read How Long Does Vocal Recording Actually Take? when planning a vocal session.
You do not have to process the complete recording. The Start and End controls let you select a particular passage. This is useful for checking how a chorus, spoken section, instrumental passage, or other part behaves after the stereo channels are combined.
The downloaded result is a WAV containing one channel. It can then be used as source audio in compatible editing and production software or become the starting point for another browser-based audio operation.
Browse Audio Tools for Recording, Mixing, and Ear Training for more utilities. Musicians developing complete songs can also explore Song Demo Production and the broader Music Genre Recording Services resources.
Simple file operations can be useful before or after a larger audio project. If you are preparing to record for the first time, Musician Psychology and Recording Confidence covers another side of the recording process.

Load the audio, choose how Left and Right should contribute, create the mono result, listen to it, and download the new WAV.
