Realtime musical outputs
AudioSlice splits a live mix into separate sources and streams a dedicated set of normalized (ie: [0, 1]) OSC control signals for each one, refreshed end-to-end in 11 ms.

- Loudness
- A smooth, normalized level for that source alone. Drive brightness, scale, opacity.
- Onsets
- A discrete trigger the instant a hit lands. Fire strobes and cuts on the transient.
- Pan
- Where the source sits in the stereo field. Move visuals left and right with the mix.
- Spread
- How wide the source is imaged. Map stereo width to blur, dispersion or field of view.
- Pitch
- Continuous fundamental frequency. Drive hue, position or geometry from the note.

Make any TouchDesigner project audioreactive
33 min · DREVOThe long one, and the best place to start. Take a TouchDesigner project that has nothing to do with audio and wire AudioSlice's OSC channels into it, parameter by parameter, until the whole patch moves with the music.
Audioreactive visuals with AI stem splitting
12 min · DREVOA quick tour of what realtime stem separation actually buys you: driving separate parts of a scene from the kick, the vocal and the melody instead of from one lump of overall level.
Realtime stem splitting, now on Windows
19 min · DREVOWatch this if you're on a PC. Covers the Windows release end to end — audio device setup, getting the stems out, and the differences worth knowing if you've only seen the Mac version.
Everything you need
Key features
A deep, dependable toolkit built for live performance and studio precision alike.
Beat & tempo tracking
Locks to the groove and follows tempo changes live. No tapping, no click track required.
Runs on CPU
The model is heavily quantized and tuned, so it sips CPU.
Heavy GPU rendering in TouchDesigner or pixel output from Resolume runs unaffected.
(Actually) realtime stem separation
Vocals, bass, drums and melody pulled apart from a full mix, every 11ms, live, with no pre-rendering.
Works with pure audio
No Pro DJ Link, no click track, no Ableton Link required.
Select any audio source and go.
Sync with Ableton Link
If you want to drive Ableton using AudioSlice's detected beat grid or vice versa, you can do it with a single click.
Save & recall projects
Every mapping and setting can be saved as portable, human-readable JSON.
Cross-platform
One license, native on macOS and Windows, with identical behaviour on both.
