Batch audio processing

Give your audio a consistent finish. Convert channels, set peak levels, add fades, and download MP3 or WAV.

Free: process one file at a time. No account needed.

Up to 20 files, 100 MiB per file, 250 MiB total input and 250 MiB retained results. Decoded audio is also limited to 250 MiB per file to protect browser memory.

Your audio stays in this browser. Reloading clears the queue and results.

Processing settings

Channels → peak normalisation → fades → encoding. A fade of 0 seconds is off. Fades shorten proportionally when they exceed the audio length.

Saved presets
