Stem Splitter and Mix / Master

Separate one selected stem with the local WebGPU model or apply level, normalization and peak limiting to a local audio track.

How it works

Make something with Stem Splitter and Mix / Master

  1. Choose a supported audio file on your device.

  2. Select the stem to separate; its model loads only after you start processing and audio is not uploaded.

  3. Preview the result, tune quiet-tail noise reduction, gain, peak normalization and limiter ceiling.

  4. Save the processed WAV to My Assets or send it to the open editor. Full-stereo Mix & Master is available as its own workspace tab.
