Each stereo WAV gives two mono WAVs: the Left channel and the Right channel, copied sample for sample. Nothing is summed, resampled or changed in level. Timecode, markers and supported metadata are kept and updated to describe a mono file.
Output filename
Each suffix is added after the original file name, exactly as typed. Characters not allowed in file names become "_".
Output
Each file is downloaded as soon as it is ready. Your browser may ask once to allow multiple downloads.
✓ Lifetime Pro feature. ✓ Your audio stays on your device. Only one file? Stereo to Mono (single file)
How the batch queue works
01. Add your stereo WAVs
Drop the whole set into the queue.
02. Check the suffixes
_L and _R by default, editable for your naming.
03. Split all
Left and Right are saved for each file, one file after another.
Your audio stays on your device
Your audio files are processed locally in your browser, one at a time. Only the file being split is held in memory; its Left and Right files are saved and released before the next one starts.
Frequently asked questions
- Is this a downmix?
- No. The Left and Right channels are never combined. Each stereo WAV gives two separate mono WAVs: one holding only the Left channel, one holding only the Right channel, copied sample for sample.
- Does the sample rate, bit depth or length change?
- No. A 96 kHz 24-bit stereo WAV gives two 96 kHz 24-bit mono WAVs of the same length. There is no resampling, no gain change and no normalization.
- How are the files named?
- Ambience.wav becomes Ambience_L.wav and Ambience_R.wav. Both suffixes can be edited (for example _LEFT / _RIGHT or _1 / _2). Duplicate names get _2, _3 and existing files are never overwritten.
- What happens to timecode and metadata?
- Both mono files keep the source's BWF timecode, so they stay in sync on the timeline. Markers keep their positions. The iXML track list is reduced to the track each file actually contains, and a coding history line records the channel extraction.
- What about mono or multichannel WAV files?
- Only stereo WAV files are split. A mono file or a file with more than two channels is marked as failed with an explanation, and the rest of the queue continues.
- Who can use batch processing?
- Batch Processing is a Lifetime Pro feature. It does not use your free conversion or pay-per-use credits.
