Frequently asked questions

Can I join different formats?
Yes. MP3, WAV, M4A, OGG, FLAC and most other audio files can be mixed. You get one MP3 or WAV back.

How long can the joined file be?
Up to 60 minutes, counting every track together.
How much of my allowance does it use?
One minute for each started minute of audio, counting every track together.

Is Audio Joiner free?
