Frequently asked questions

What input formats does this accept?+

Anything your browser can decode natively — MP3, WAV, OGG, M4A/AAC, and FLAC in most modern browsers.

Will this work for a full song, or just short clips?+

It handles full-length tracks — decoding and encoding both happen in memory, so the practical limit is your device's available RAM, not a fixed duration cap.
