Local MLX processing on Apple silicon handles high-quality vocal isolation, acapella extraction, and four-stem separation with a dedicated model for each phase.

GOOD CLEAN STEMS Mac stem splitter with vocal isolation settings

FIRST PASS

Give every stem the right set of ears.

Drop in a song, choose the outputs you need, and get industry-leading vocal isolation, acapella extraction, or four-stem separation locally. In published benchmarks, the new default Leap XE produced a signal-to-distortion ratio about 41% higher than fine-tuned Demucs v4. Choose Kim FT3, FT2 Bleedless, Leap, or Leap XE for the vocal pass. Kim Inst V1E handles the instrumental pass, while BS-RoFormer-SW handles four-stem separation. On the same Apple silicon hardware, MLX ran up to 2.50x as fast as PyTorch across the tested model families.
