# → ComfyTV Audio

> **Into-bridge**: ComfyUI **AUDIO** dict → **COMFYTV_AUDIO** wav URL. **▶ Run** writes `output/ComfyTV/bridge/*.wav`.

## 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.

## Types

| Native `AUDIO`        | ComfyTV `COMFYTV_AUDIO` |
| --------------------- | ----------------------- |
| tensor + sample\_rate | wav `/view?` URL        |

## Parameters

### audio

Upstream **AUDIO**. Required.

## Outputs

| Output    | Type            | Downstream                         |
| --------- | --------------- | ---------------------------------- |
| **audio** | `COMFYTV_AUDIO` | Video Stage **audio**, Audio Stage |

## Step by step

1. Native node → AUDIO.
2. **→ ComfyTV Audio**, wire, **▶ Run**.
3. Wire to **Video Stage** **audio** (IA2V).

## 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**.
