Audio Notify Audio Trigger

Audio Notify Audio Trigger is the trigger node in ComfyUI-Audio-Notifier that takes an AUDIO, plays a sound, and returns nothing. It's the dead-end version of Audio Notify Audio - the same "your generated audio is ready" signal, without forwarding the AUDIO anywhere.

It fits the niche audio-generation corner of ComfyUI: text-to-audio or music pipelines where a generation node produces an AUDIO tensor and you're waiting on it. Branch the trigger off that output:

Audio Generator
├── Save Audio
└── Audio Notify Audio Trigger

The trigger fires the moment the audio is ready, and because it's a trigger your save wire stays untouched - no node inserted into the path that matters. There's a mild joke in a node that plays a sound to tell you an audio generation finished, but it works, and the notification is distinct from whatever your pipeline generated.

Two clarifications so nothing surprises you. First, the AUDIO input is ComfyUI's in-graph audio type from audio-gen nodes; the trigger plays a separate notification sound, it does not play the audio you feed it. Second, "ready" is not "saved" - in the parallel layout above, the save might still be writing when the chime fires, since ComfyUI doesn't guarantee branch order. Want the bell to mean "the file is on disk"? Hang the trigger after the save node instead. And prefer .wav for the notification sound; non-WAV playback leans on ffplay on some platforms.

Inputs

• audio - the AUDIO that triggers the sound.
• notification_enabled - mute the node.
• delay_seconds - hold the chime.
• repeat - 1–100 plays.
• blocking_playback - off by default (background thread); on to wait for playback.
• enable_sound_path / sound_path and enable_sound_name / sound_name - sound source: absolute path, or a file in the pack's sounds/ folder.
• fallback_to_system_beep - beep if nothing resolves, on by default.

No outputs.

Install and gotchas

No dependencies, no models. Clone and restart the backend:

cd ComfyUI/custom_nodes
git clone https://github.com/uni-miao/ComfyUI-Audio-Notifier.git

Restart the ComfyUI backend process, not just the browser tab. Pack-wide gotchas: the sounds/ folder ships empty, so add files (or use an absolute sound_path) and restart before the dropdown has choices; and audio always plays on the machine running the backend - if ComfyUI is on a server, that's where the chime comes out, not your laptop.
