Note 1: The model outputs only those instruments that were detected in the musical composition. Instruments that are not present in the track are not included in the output.
Note 2: Individual models for each instrument generally produce better results than this multimodel. Therefore, it is recommended to use this model to determine the set of stems first, and then extract them using separate instrument-specific models trained on narrower tasks.
Note 3: To reduce disk space usage, results are saved in all formats except WAV (FLAC is used instead of WAV).
Note 4: This model differs from our previously published open-source model and is an improved version of it. The comparison table below is provided:
