What Runs Behind the Tools

Cloud Standard uses a third-party separation model through WaveSpeed. Local 6 tracks runs the open-source HT-Demucs model (htdemucs_6s) in your browser with ONNX Runtime Web, so the audio stays on your device.

Demucs

The Demucs code and its released model weights are published by Meta under the MIT licence (licence text). SampLab Pro is not affiliated with Meta or the Demucs authors. The notice that lists every component of the local engine, its version and its licence is stem-model-NOTICE.

Training Data: An Open Question

The Demucs authors state that their models were trained on the MUSDB18-HQ dataset plus 800 additional songs. MUSDB18-HQ is released for research use. The MIT licence covers the code and the released weights and says nothing more about the training data, so it is not settled what applies to the tracks a model makes. We do not promise that tracks made here are cleared for commercial use.

Your Audio and Your Tracks

Rights in your audio stay with you or with the rights holder. Separating a recording gives you no rights in it. Before you publish, sell or sample a track, make sure that you hold the rights to the original recording and composition, and take the open question above into account.

Demo Audio

The demo song and its separated tracks on our pages were generated by SampLab Pro with AI (the Mureka model through WaveSpeed) for demonstration only, and were separated with the Local 6 tracks engine. No licence is granted to reuse them (note).

Playback Sounds

The audio to sheet music tool plays scores with MuseScore_General, a General MIDI sound font released under the MIT licence (Copyright Frank Wen, Michael Cowgill and S. Christian Collins; Temple Blocks by Ethan Winer; Drumline Cymbals by Michael Schorsch). We serve it as three smaller files and change nothing in the samples. The licence text, all credits and the list of changes are in MuseScore_General-MIT.
