Questions, answered.
Is my audio uploaded?
No. Trimming happens entirely in your browser via the Web Audio API.
What formats are supported?
MP3, WAV, OGG, M4A — anything your browser can decode. Export is WAV.
Why WAV and not MP3?
MP3 encoding needs a heavy library. WAV is lossless and plays everywhere.
