826141a319 Audio processor: working voice profiler with WavLM speaker embeddings
- Voice profiler using microsoft/wavlm-base-sv (512-dim x-vector embeddings)
- Bootstrap from archive: 180 embeddings from 9 episodes across 2010-2018
- Host identification accuracy: 0.87-0.98 similarity for live speech,
  0.60-0.64 for non-host audio (produced intros, co-host)
- Dropped speechbrain dependency (requires torchaudio, CUDA version conflicts)
- Patched torchaudio CUDA 12.8/13.1 version check (warning instead of error)
- Profile stored in voice-profiles/mike-swanson/ with per-chunk embeddings

87f5a9306a Audio processor: fix segment detection with transcript-driven breaks
- Add transcript break phrase detection (going_to_break/coming_back cues)
- Create segments from transcript breaks with silence boundary snapping
- Fix segment dedup in merge_adjacent (handle overlapping segments)
- Add CUDA 12 library path fix (gpu.py + venv activate hook)
- Auto-load existing transcript in detect command
- Tested on 2011-03-05 HR1: correctly identifies commercial break at 34:38

a1e0442d8b Add radio show audio processor and post-show workflow
- Audio processor CLI tool with 6-stage pipeline: transcribe (faster-whisper GPU),
  diarize (pyannote), detect segments (multi-signal classifier), remove commercials,
  split segments, analyze content (Ollama)
- Post-show workflow doc for episode posts, forum threads, deep-dive blog posts
- Training plan for using 579-episode archive for voice profiles and commercial detection
- Successful test: 45min episode transcribed in 2:37 on RTX 5070 Ti
- Sample transcript output from S7E30 (March 2015)
