Load Audio from Asset

Pick audio from the ComfyTV project asset library—reuse Speech/Music Stage output or imports for Video Stage, timelines, or reference audio.

What this node does

Load Audio from Asset lets you browse audio assets for the current project inside the node: categories, search, entry list. A click outputs a COMFYTV_AUDIO snapshot—no ▶ Run.

Library audio typically comes from Speech Stage, Music Stage, Demux, or sidebar imports. Complements Load Audio (input/ folder).

When to use it

• Reuse the same voiceover without re-running Speech Stage.
• Wire generated BGM to Video Stage → audio (IA2V).
• Feed Speech Stage → reference_audio for cloning/style.
• Optional track on Director Timeline → audio.

How it works (why ComfyTV is designed this way)

• Instant stage: Selection → snapshot; no workflow.
• Snapshots: Downstream Runs use the selected URL; picking another updates it.
• Project scope: Only artifacts under the same Project appear.
• Load vs generate: This node loads existing audio; Speech/Music Stage creates new audio (key FAQ distinction).

Types (COMFYTV_* vs native ComfyUI)

ComfyTV type	What it is	vs ComfyUI native
COMFYTV_AUDIO	Audio URL snapshot	Not AUDIO tensor
COMFYTV_VIDEO	Video with audio	Demux to library first
Native AUDIO	Tensor	→ ComfyTV Audio Bridge

UI and parameters

Asset picker

• Thumbnails/waveform (UI-dependent), categories, search.
• Empty library → run Speech/Music Stage or import first.

asset_url / asset_id / category (hidden)

• UI-written; category filter persisted.

project_id / parent_output_id

• Hidden internals.

Outputs

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

Step by step for beginners

1. Add Project and name it.
2. Run Speech Stage or Music Stage (or import via sidebar).
3. Add Node → Input → Load Audio from Asset.
4. Click the target audio in the node body.
5. Wire to Video Stage → audio or other consumers.
6. ▶ Run downstream if it’s a generator stage.

FAQ

Q: vs Load Audio (input/)?
A: External files → Load Audio. Project generated/imported → this node.

Q: vs Speech Stage?
A: Speech generates; this picks from the library. No TTS here.

Q: Type mismatch?
A: Expect COMFYTV_AUDIO; Bridge native AUDIO into the library first.

Q: Empty after category filter?
A: Switch to all; confirm assets exist in that category.
