Stem separation runs live on your system audio, close enough to follow a video. Under load, the latency compensates in inaudible micro-shifts. The stems keep the quality of file-based separation.
runs offline & on-device
The model sets the quality.
As a test version and proof of concept, the beta runs Demucs, the separation model from Meta AI. The model can be replaced in future versions to raise quality. Today the quality is the same as in file-based separation.
A layer around the model.
Making offline models run on a live audio stream. With a gapless and stable listening experience for hours.

Stem-specific meteringVisualize separate live-stems while listening to the whole track. 5 metering modules, each one with its own suite of properties and color customization.
Live stems in your DAWSelect the virtual device as input in your DAW and bring the live stems to your channels.
App specific volume controlMute, boost and mix all apps on one set of faders.
Microphones and instrumentsAdd microphones or instruments to the same virtual device and set their volume in the mix.
Combine output devicesSend the same mix to a collection of end devices and control their volume in the same interface. Bluetooth speakers, interfaces or surround systems, any collection gets an identical, temporal synced mix.
Route between appsRoute the live audio stream of an isolated app into another app.
Combine audio sourcesControl the mix of your microphone and app in one place and record them together to a different app.
Multi channel routingSet the channels and each source gets recorded as separate track in your external app.
Instant recordingRecord any source in the same volume interface on the fly. Sample live-stems or record system audio and drag & drop the files with ease.
3 · Overlay
Attach the multi-tool to any viewport
Pin the volume interface to any desktop or app scene to keep it visible. Un-pin it to show it only when pressing the volume keys.
Overlay
Let the metering modules join the volume interface in the glass-overlay. Save setups as session states or apply the same to multiple viewport scenes.
