Frequently asked questions
- What is a poly WAV?
- A polyphonic WAV is a single interleaved file holding every channel of a multitrack recording — boom, lavs, plants and mixes together. Field recorders like Sound Devices, Zoom and Zaxcom write them by default.
- How many channels can it split?
- Up to 32 channels. Each one is exported as its own mono WAV with the original sample rate and bit depth.
- Can I name the tracks?
- Yes. Rename each channel before export — Boom, Lav1, Plant — and the filenames follow.
- Is my recording uploaded to a server?
- No. The split runs in your browser, which matters when the file is a confidential interview or an unreleased production.
