Audio · Vocals Only

Roadmap / pending — Demucs vocal stem separation from video/mix. Workflow slot exists; backend not wired.

Audio · Vocals Only · screenshot coming soon

Intended purpose

Audio · Vocals Only takes COMFYTV_VIDEO (or demuxed audio path), runs a Demucs-style workflow, outputs isolated vocals as COMFYTV_AUDIO. Lip-sync, vocal replace, karaoke prep, etc.

⚠️ Current status: workflow dropdown scans workflows/audio-vocal/ (no shipped JSON yet). Run fails without backend. Planned: lum3on/ComfyUI_AudioTools AudioStemSeparate. See roadmap.md.

When to use it (once shipped)

• Extract vocals from MV for IA2V / TTS alignment
• Process vocal stem in Audio Stage
• Pair with Background Only

Planned design

• Stage + workflow + ▶ Run + snapshot.
• Input: upstream videos: [video], no text prompt.
• Demucs stem → WAV → COMFYTV_AUDIO URL.
