Join audio files into one
Line up songs or recordings, add a crossfade, and save one file. Free, no sign-up, nothing uploaded.
Putting the mix under a video?
If the video already has music you can’t use, Music Remover takes it out and keeps the voice. Voice Isolator gives you the speaking alone.
How to join audio files
- 1Add the filesUp to 20 songs or recordings, in any mix of formats.
- 2Put them in orderMove files up and down, and pick a crossfade to blend each join.
- 3Save one filePick the format; the joined file saves straight to your computer.
Does the audio joiner upload my file anywhere?
No. The file is opened and converted by your own browser, and the result is saved straight to your computer. Nothing is sent to us, so there is nothing for us to keep or delete.
Can the files be in different formats?
Yes. MP3, WAV, M4A, FLAC and the rest can be mixed, and videos add their sound. Every file is matched to the others before they are joined, so the joins are clean.
What does the crossfade do?
It fades one file out while the next fades in, so a mix runs on without a gap. Off joins the files end to end. A crossfade is never longer than half the shortest file.
How many files can I join?
Up to 20 at a time, 1 GB together. To join more, join them in batches and then join the results.
