Algorithm for extracting only lead vocals and everything else based on the MelBand Roformer model. It works for any music track, but you can also pre-extract vocals by selecting the "Extract vocals first" option in Extraction type. In the second case, back vocals will be available in a separate file.

There are 2 models, one prepared by the team @aufr33 and viperx, the second by @becruily.

Quality metrics are given below. For comparison, the table also provides quality metrics for the old UVR and MDX-B Karaoke algorithms.
