Comfyui Soundfx Creator

Inputs to Collect

Ask the user (or previous skills) for:

• SFX description
  • What happens (event) and how it should feel (timbre/mood).
• Target timing
  • Approximate timestamp(s) in a given video clip (e.g., clipId + seconds).
• Duration
  • Usually 0.2–2 seconds; up to 5–10 seconds for stingers or sweeps.
• Usage context
  • Game/UI/film/trailer/website, etc.
• Tone / timbre
  • Soft / hard, metallic / organic, digital / analog, retro / modern.
• Format & sample rate
  • Default: WAV, 44.1 kHz or 48 kHz, mono or stereo.

Expected Behavior

1. Normalize the request to SFX parameters:
   • eventDescription, durationSeconds, intensity, timbre, targetClip, timecode.
2. Choose or build an SFX generation workflow:
   • Text‑to‑audio SFX model, synthesis chains, or layering of primitives.
3. Generate one or more SFX variants.
4. For each variant, collect:
   • audioUrl / audioPath
   • durationSeconds
   • format, sampleRate, channels
5. Optionally suggest which variant best fits the described moment.
6. Return a concise list of SFX assets plus their metadata.

Output Format (to the caller)

Return a structure such as:

• effects: array of:
  • name
  • description
  • audioUrl or audioPath
  • durationSeconds
  • format
  • sampleRate
  • channels
  • targetClipId (if provided)
  • timecode (if provided)

Orchestration Notes

Typical pipeline:

1. Use comfyui-video-generator to create scenes.
2. Use comfyui-audio-creator to generate music/ambience.
3. Use comfyui-soundfx-creator to add moment‑specific SFX for key beats.

This skill does not perform final mixing; it only produces clean SFX assets and metadata so a separate mixer/editor can place them accurately on the timeline.
