What does Audio Joiner do?

Combining several audio tracks can mean placing clips one after another or layering them so they play together. This audio joiner supports both a sequential join and a simultaneous normalized mix.

Reorder up to 20 source tracks, choose the output format and encoding settings, listen to the result, and download one file. Processing runs locally with a WebAssembly engine.

Join tracks in sequence or mix all tracks from the same starting point.
Control order, output format, bitrate, sample rate, and channels.
Process audio locally without uploading it.

Common use cases

Combining recorded voice segments
Mixing narration with background audio
Joining lesson audio into one file
