FAQ

Can I mix formats?+

Yes. The browser decodes each file (WAV, MP3, OGG, M4A, FLAC) into raw audio first, then re-encodes them as one file in your chosen output format.

Does it crossfade between clips?+

No, this tool does straight concatenation — clips play one after the other with no overlap. For crossfades use a DAW.
