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).

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.

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.
  • Load Audio — raw input/ files.
  • Speech Stage / Music Stage — write new audio.
  • Video Stage — consumes audio for IA2V.
  • Director Timeline — timeline audio track.
  • Load Video from Asset / Load Image from Asset — sibling nodes.
