    Join audio files into one

    This free audio joiner combines several sound files into a single track: songs into a continuous mix, chapters of an audiobook, parts of a podcast, or WhatsApp voice notes into one file. Drag the files into order and choose how they meet: joined directly, with a smooth crossfade, or with a short pause. Tick Same volume for every file so no track jumps out.

    Questions

    Can I join files with different formats or quality?

    Yes. They're all converted to the same sample rate and channels before joining.

    Is there a length limit?

    Several hours of audio work on most computers. WAV output of very long mixes can be large; choose MP3 to keep the file small.
