FAQ
- What audio formats can I upload?
- Any format your browser can decode (MP3, WAV, M4A, OGG, etc.) via the Web Audio API.
- Why is the output always WAV, even if I uploaded MP3?
- WAV is lossless and simple to encode reliably in the browser without a codec library. Re-compressing to MP3 is a separate feature not built yet.
- Does this tool upload my audio anywhere?
- No — trimming happens entirely in your browser with the Web Audio API.
