How to join audio files
- Choose two or more MP3 or WAV recordings. You can add more files afterward.
- Use the up and down arrows to arrange them. Remove any track you do not need.
- Preview the combined audio, choose an output format and prepare your download.
The recordings play one after another with no inserted gap or crossfade. Silence already inside a recording stays in the result. Trim unwanted silence first.
Channels, timing and limits
Use up to six files, 60 MB combined and five minutes total. Browser decoding converts inputs to the same sample rate. If you mix mono and stereo, the output is stereo and the mono recording is copied to both channels.
WAV preserves the combined decoded sample duration. MP3 is re-encoded and may add a little encoder padding. This is joining, not overlapping or mixing tracks. Only join recordings you have permission to use.
