LightCut Music Analysis Models
ONNX inference weights used by LightCut's browser-local music structure analysis.
All audio decoding, source separation, feature extraction, and inference run in the user's browser.
Files
htdemucs-core.onnx: four-stem HTDemucs source-separation core.harmonix-fold0.onnx through harmonix-fold7.onnx: eight-fold All-In-One music-structure-analysis ensemble.
Intended Use
These files are packaged for inference. They predict tempo, beats, downbeats, section boundaries, and section labels for music audio. The LightCut integration supports audio-bearing media between 76 and 660 seconds.
