Separating a finished mix into vocals, drums, bass and other groups can help when the original session is unavailable. However, an algorithm does not recreate the original tracks perfectly: bleed, digital residue and phase changes may remain.

Separating a finished mix into vocals, drums, bass and other groups can help when the original session is unavailable. However, an algorithm does not recreate the original tracks perfectly: bleed, digital residue and phase changes may remain. What AI stem separation can do, its artifacts and legal limits, and when original session stems are essential.
