What this node does

ComfyUI audio nodes output AUDIO {waveform, sample_rate}. ComfyTV Video Stage (IA2V) and Audio Stage expect COMFYTV_AUDIO URLs. → ComfyTV Audio saves WAV via torchaudio on Run (universal, no codec deps). Use for Stable Audio, ACE-Step native output, or any plugin AUDIO into ComfyTV.

​
When to use it

  • Native music gen → ComfyTV Video Stage IA2V
  • External TTS / SFX → ComfyTV timeline (future)
  • Processed AUDIO in ComfyUI → back into ComfyTV

​
How it works

  • Stage + ▶ Run; _save_audio_to_disk → WAV.
  • Normalizes 3D waveform [1, channels, samples].
  • Snapshot /view? for IA2V etc.

FAQ

Q: Queue vs Run?
A: Run = ComfyTV stage / into-bridge snapshot (required for this node); Queue = execute full ComfyUI graph. Into-bridges cannot substitute Run with Queue. Q: Demux already COMFYTV_AUDIO?
A: No bridge needed — Demux is already ComfyTV. Bridge is for native AUDIO. Q: wav location?
A: output/ComfyTV/bridge/*.wav. Q: Sample rate changed?
A: Preserves source sample_rate.
