Load Audio

Pick or upload local audio from ComfyUI’s input/ folder as the starting point for ComfyTV audio pipelines—voiceover, mixing, and IA2V video inputs.

What this node does

Load Audio is an instant Input stage. It reads audio files from ComfyUI’s input/ folder (or uploads written there), registers a project snapshot, and outputs COMFYTV_AUDIO.

Use it for existing BGM, voice WAV, demuxed tracks, etc.—not for AI generation. Selecting a file immediately sets output without invoking Speech or Music Stage workflows.

vs Load Audio from Asset: this node = raw disk files; asset loader = project library from runs and imports.

When to use it

• Import external narration, music (FLAC/WAV/MP3).
• Feed reference audio into Speech Stage (voice cloning).
• Wire into Video Stage → audio for image+audio-to-video.
• Optional track on Director Timeline.

How it works (why ComfyTV is designed this way)

• Stage vs Run: No ▶ Run—select or upload to output.
• Snapshots: Downstream Runs read the current file URL; they won’t re-read this node automatically.
• No workflow: Not tied to workflows/audio/ or workflows/speech/ generators.

Types (COMFYTV_* vs native ComfyUI)

ComfyTV type	What it is	vs ComfyUI native
COMFYTV_AUDIO	Audio file URL snapshot	Not in-memory AUDIO tensor
COMFYTV_VIDEO	Video snapshot	Demux to audio, then load or asset-pick
COMFYTV_TEXT	Text snapshot	Speech output—not the same as file load

Conversion:

• Native → ComfyTV: → ComfyTV Audio
• ComfyTV → native: ← ComfyTV Audio

UI and parameters

audio

• What: Dropdown of audio in input/ plus upload.
• What to set: Pick or upload (WAV, MP3, FLAC, etc.).
• Effect: Defines source audio for downstream; must be a format ComfyUI recognizes.
• Common mistake: Looking here for Music/Speech Stage outputs—use Load Audio from Asset or wire from the generator.

project_id / parent_output_id (internal)

• Hidden; maintained by Project and wiring.

Outputs

Output	Type	Meaning	Typical downstream
audio	COMFYTV_AUDIO	Selected audio snapshot	Video Stage (audio), Director Timeline (audio), Speech Stage (reference_audio), audio extract stages

Step by step for beginners

1. Add Node → ComfyTV → Input → Load Audio.
2. Wire a Project node (recommended).
3. Put files in input/ or upload here.
4. Select in dropdown—no Run needed.
5. Connect audio downstream, e.g. Video Stage → audio.
6. ▶ Run the downstream generator.

FAQ

Q: Load vs generate (Speech/Music Stage)?
A: Load Audio = existing files, no GPU inference. Speech/Music = AI creation with workflow + Run. Loaders import; generators create.

Q: Load Audio vs Load Audio from Asset?
A: This = input/ disk. Asset = project library after generation/import.

Q: Type mismatch?
A: Downstream must expect COMFYTV_AUDIO; native AUDIO needs → ComfyTV Audio Bridge.

Q: No Run button?
A: Normal—same as Load Image/Video.
