Splitting multichannel audio into separate tracks, step by step
A single multichannel file, whether a multichannel WAV, AIFF, FLAC or MP3, becomes one file per channel. Everything runs in your browser, the audio file is not uploaded.

Watch the tutorial below to see how to split a multichannel audio file into separate individual tracks directly in your browser.

Split your multichannel audio1. Import
Load the multichannel file you want to separate.
- Drop a WAV, AIFF, MP3, M4A, FLAC or OGG file on the drop zone, or click to browse.
- Check the spec strip: channel count, sample rate, bit depth and duration.
- Each channel is listed with its own waveform so you can see what it contains.
Tip If the file is a field recorder poly take with iXML track names, the PolyWAV Splitter page is written around that workflow.
2. Select channels
Only the channels you keep are written out.
- Untick any channel you do not need, for example an unused plant mic.
- Rename the channels you keep; the name becomes the file name.
- Solo a channel in the player to confirm its content before exporting.
3. Export
One file per selected channel.
- Leave the export settings on Source to keep the sample rate and bit depth of the file.
- Choose WAV for editing; AIFF and MP3 are available on Pro.
- Download channels one by one, or export all of them as a single ZIP.
4. Quality control
Two minutes of checks before the files leave your machine.
- Reimport one exported track and confirm it is mono and the right length.
- Check sample rate and bit depth in the Audio Inspector.
- Confirm no exported track is unexpectedly silent.
Frequently asked questions
- Which formats can I split?
- Any file your browser can decode: WAV, AIFF, MP3, M4A, FLAC and OGG. Multichannel WAV is the most common case, but the splitter is not WAV only.
- Can I export only some channels?
- Yes. Deselect the channels you do not need before exporting; only the selected ones are written out.
- Is the audio changed?
- No, as long as the export settings stay on Source and you export WAV: sample rate and bit depth are copied and each channel's samples are written unchanged.
