An end-to-end recipe combining faster-whisper transcription, demucs vocal separation, and NVIDIA NeMo's MSDD diarizer. Outputs RTTM + SRT with speaker labels. BSD-2-Clause.

Best for: Meeting transcripts where 'who said what' matters more than raw speed.
Watch out for: Heavy dependency tree (NeMo, faster-whisper, demucs); GPU strongly recommended.
