Comfyui Audio Creator

When to Use

• After video clips exist and the user wants music or ambient soundscapes for them.
• The user asks for background tracks for a trailer, promo, or game scene.
• You need loopable ambience (e.g., city at night, fantasy forest, sci‑fi engine room).

Inputs to Collect

Ask the user (or previous skill) for:

• Audio type
  • music or ambience (no voice).
• Target scene(s)
  • Reference to clips from comfyui-video-generator (IDs, durations, moods).
• Style / genre / mood
  • Music: orchestral, synthwave, lofi, rock, cinematic, etc.
  • Ambience: forest, city, sci‑fi engine, horror, cozy home, etc.
• Duration
  • Typically match the clip length or a loopable segment (e.g., 15–60 seconds).
• Loopability
  • Whether the audio should seamlessly loop.
• Tempo / intensity (for music, optional)
  • Slow/medium/fast; low/medium/high intensity.
• Format & sample rate
  • Default: 16‑bit WAV, 44.1 kHz or 48 kHz, stereo.

Expected Behavior

1. Map the request into structured audio parameters:
   • audioType, genre, mood, durationSeconds, loopable, targetScenes, tempo, intensity.
2. Select the appropriate ComfyUI or connected audio workflow:
   • Music generator or ambience generator (no TTS here).
3. Generate audio in one or more segments:
   • Ensure total duration covers the referenced scenes.
   • For loops, ensure clean loop points.
4. Collect:
   • audioUrl / audioPath
   • durationSeconds
   • format, sampleRate, channels
   • Tags/metadata (genre, mood, bpm if known).
5. Return a concise summary plus technical details.

Output Format (to the caller)

Return a structure containing:

• description: e.g. “Loopable synthwave track for the opening scene.”
• audioUrl or audioPath
• durationSeconds
• format
• sampleRate
• channels
• loopable: boolean
• tags: list of strings (genre, mood, tempo)

Orchestration Notes

Typical pipeline:

1. comfyui-video-generator → create scenes.
2. comfyui-audio-creator → create background music/ambience for those scenes.
3. comfyui-voice-generator → add narration or dialogue.
4. comfyui-soundfx-creator → layer in moment‑specific sound effects.

This skill focuses on non‑voice background audio so other skills can handle speech and SFX cleanly.
