WAV channel splitter
Separate channels already stored in a WAV recording so you can edit each microphone or speaker feed independently. Standard stereo uses channel 1 for left and channel 2 for right. The report lists declared speaker positions when available. Samples are copied directly, retaining their rate, container size and valid precision. Each exported file plays as a single mono channel.
How to use this tool
- Upload a stereo or multichannel WAV, or import its direct public URL. Try the example recording with a different tone on each side.
- Choose all channels or select a channel number that exists in the recording, then create the result.
- Listen to the mono previews and download individual WAVs or the ZIP. Use the CSV report to check sample rate, precision, frame count and source channel positions.

Output and limitations
Split a stereo or multichannel WAV into separate mono WAV files. Choose all channels or one channel, preserve sample bytes and sample rate, and download a ZIP with a channel report.
One RIFF WAV up to 20 MB with 2–8 channels. Supports PCM 8/16/24/32-bit and IEEE float 32/64-bit, including compatible extensible WAV, up to 384 kHz. Compressed WAV, MP3, RF64 and RIFX are unsupported. Output is centered mono; cue points, timecode and other source metadata are omitted.
Will splitting change volume, sample rate or precision?
The exported sample bytes stay unchanged. There is no resampling, normalization or mixing. Each output is mono and does not keep the original speaker panning. Audio previews depend on browser support; downloads preserve the supported source sample format.
Can this separate two voices mixed in one channel?
No. It extracts existing channels, not speakers or instruments within a mixed channel. An interview recorded with one microphone on each stereo side can be split. A mono recording cannot be separated into different voices with this tool.
What if processing fails?
Check the supported formats and file limits, then try a smaller file. Keep an original copy. A clear error message will explain an unsupported input or an unavailable processing service.
