Add a spatial ambient SFX layer to a finished avatar reel and deliver it as final-espacial.mp4, without overwriting final.mp4. Generates positioned ambient/foley beds + one-shots (birds, water, gulls, fire crackle, crickets, wind, etc.) with audio-theater (ElevenLabs Sound Effects), mixes them on a virtual stereo stage (pan + distance + movement) with mix_spatial.py, and overlays them ducked under the narration. Use when the user wants to "ambientar más" / add ambient or positional/spatial…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Avatar Ambient SFX (spatial sound design for reels) Layer a **spatial ambient sound bed** over a finished reel so each "world"/location (garden, water, fire, plaza…) gets its own positioned atmosphere, and deliver it as **`final-espacial.mp4`**. The narration always stays on top; `final.mp4` is never touched. This skill is a thin orchestration on top of **`audio-theater`** (which provides the SFX generator and the spatial mixer) plus one overlay script in this skill. ## When to use The reel is already finished (`final.mp4` with narration + music + captions + fade), and the user wants to "ambientarlo más" / add ambient, positional, or spatial sound that follows the different worlds in the video. Best when the reel is a **journey across distinct locations**. ## Prerequisites - The finished reel folder must contain: `final.mp4`, `narration.mp3` (narration-only track, the sidechain key), and ideally `narration.align.json` (for the fade timing). - `audio-theater` scripts available at `~/.cursor/skills/audio-theater/scripts` and an **ElevenLabs key** set (realistic foley). Verify: `python3 ~/.cursor/skills/audio-theater/scripts/setup_key.py --show`. …

How to install
mdr add puntorigen/avatar-skills/avatar-ambient-sfx@sha256:1f73767689392485The line at the top of this page pins the label git:20260709.ec45941, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
