Good to know
- Files with the same format and settings (for example MP3s from one recorder) are copied together without re-encoding.
- Otherwise, or with a pause between files, the sound is converted to MP3, M4A, WAV or OGG, at the first file's sample rate.
- MP3 files keep their few milliseconds of encoder padding at each join.
- Video files work too: their sound is used.
