Use when the user wants music, voiceover, narration, or a soundtrack added to a video asset, OR wants standalone generated audio for any purpose (e.g. "/audio-track", "add music to the launch video", "narrate the demo", "make a 30 second music sting", "generate a voiceover mp3", "jingle for the intro").
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
# Audio Track **REQUIRED BACKGROUND:** marketing-studio skill. Work in `C:/Projects/animations`. Read `C:/Projects/animations/docs/playbook/audio.md` first (endpoints, ducking, manifest contract). Every film gets this pass; it is not opt-in (CLAUDE.md: a film is not done without audio, and audio means narration). `node scripts/check-audio.mjs <brand> --project <product>` is the exit gate for all three recipes that touch video. Three modes; pick by what the target is: - **Bespoke film** (`studio/src/films/<brand>/`, e.g. PostflopFilm) — post-render scoring with `scripts/build-<brand>-film-audio.mjs` + `scripts/score-film.mjs`. Recipe A0. - **Video soundtrack** — a directed LaunchVideo composition scored with music and voiceover inside the product workspace. Recipe A. - **Standalone audio** — a music track and/or narration mp3s delivered as files (a sting, a jingle, a narration for something outside this studio). Recipe B. Both need `ELEVENLABS_API_KEY` in the repo `.env` (missing key = feeder exits 2; videos stay silent). Generation costs real money: one pass, trim copy rather than regenerate blindly. Free tier returns 402; Starter or above required. …

How to install
mdr add ucsandman/claude-skills/audio-track@sha256:a92c6a6450d33e54The line at the top of this page pins the label git:20260915.793ae04, 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.
