​
What this node does

Audio Picker is a Compose stage (ComfyTV/Compose). Upstream stages that produce audio—Music Stage, Speech Stage, or any node whose runs pile up multiple takes—feed into this node. The node body shows the accumulated tracks; whichever one you click becomes the sole COMFYTV_AUDIO on the audio output. There is no ▶ Run. Clicking a track updates the hidden selected_index and re-emits the output snapshot instantly, so downstream stages immediately see your pick. Media flows as ComfyTV project snapshots, not native ComfyUI tensors. To hand a picked track to native ComfyUI audio nodes, insert a Bridge — see bridges.md.

​
When to use it

  • A Music Stage returns several takes across multiple Runs and you want to audition and keep one.
  • You generated a few Speech reads of the same line and need to choose the best delivery.
  • You want to accumulate takes across Runs into one pool and pick without losing earlier ones.

​
Parameters

​
batch (upstream)

The wired input, of type COMFYTV_AUDIO and optional. Each generated track that arrives here is appended to the pool. Wire it from a Music Stage or Speech Stage audio output.

​
selected_index (hidden)

1-based index of the track to extract (default 1, range 1–999). You never type this—it is set by clicking a track in the node body.

​
pool (hidden)

Accumulated audio pool, stored as JSON on the node. The UI appends new upstream tracks (deduped by URL) so they survive regeneration and disconnect, and empties it via the Clear button. When the pool is non-empty it is the source; otherwise the live batch input is used.

​
project_id / parent_output_id (internal)

Hidden; maintained by the Project node and graph wiring. You rarely touch these.

Outputs

Tips

  • Nothing appears until you actually click a track—selection, not hover, sets the output.
  • Pool cluttered with old takes? Use Clear in the node body, or drop in a fresh Audio Picker.
  • The pool persists selections and takes with the project, which native in-memory audio tensors cannot—use a Bridge only when crossing to native nodes.
  • Music Stage — common upstream; generates instrumental / vocal tracks.
  • Speech Stage — text-to-speech upstream.
  • Image Picker / Video Picker — same pick-one-from-a-pool pattern for other media.
  • Load Audio from Asset — pull an existing track from the project asset library instead of picking from a pool.
