What it does
Audio Track is an agent skill from ucsandman/marketing-studio. 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").
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Text to speech and voice and Music and audio generation. The repository describes itself as: Create product launch assets with Remotion, then review and distribute them through guarded, dry-run-first workflows. The licence is MIT.
When your agent uses it
- The user wants music
- A soundtrack added to a video asset
- Wants standalone generated audio for any purpose (e.g
Example prompts
- “/audio-track”
- “add music to the launch video”
- “narrate the demo”
- “/audio-track”
Requirements
- A credential in ELEVENLABS_API_KEY
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Shared-repo guard + toolchain per marketing-studio.
- Copy source of truth: scripts/build--film-audio.mjs (copy postflop's).
- Run it (VO lines and the exact-length bed hit the API once; re-runs reuse files,
- node scripts/score-film.mjs --project — refuses
- Listen-proof: node scripts/verify-cue.mjs on one
What it can do on your machine
Read from SKILL.md and the folder at commit 66cd1c3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ELEVENLABS_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Audio Track loads about 1.1k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 567 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Audio Track
REQUIRED BACKGROUND: marketing-studio skill. Work in ${CLAUDE_SKILL_DIR}/../...
Read ${CLAUDE_SKILL_DIR}/../../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 withscripts/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.
Recipe A0: bespoke film
- Shared-repo guard + toolchain per marketing-studio.
- Copy source of truth:
scripts/build-<brand>-film-audio.mjs(copy postflop's). Narration lines carry the film SECOND they start on, computed from the film's timeline.ts so a re-timed shot moves its line with it; SFX cues carry the frame the shot lands something on (Stamp/Rule/click constants + the shot'sfrom), max two per beat. Budget ~2.6 words/second minus a 150ms breath per line. - Run it (VO lines and the exact-length bed hit the API once; re-runs reuse files,
--force <id,...|music>regenerates). Read the printed start/end table: every line inside its shot. node scripts/score-film.mjs <brand> <product-film> --project <product>— refuses overlapping lines (trim copy, re-run the builder) and zero-VO manifests; masters by measured gain and verifies the DELIVERED file (I within 0.5 of TARGET_I, TP <= -1).- Listen-proof:
node scripts/verify-cue.mjs <scored.mp4> <voStart> <voDur>on one narration window and one bed-only window (voice ~6 dB above the bed), thennode scripts/check-audio.mjs <brand> --project <product>(exit 0), then SEND the scored file.

Recipe A: video soundtrack
- Shared-repo guard + toolchain per marketing-studio.
- Copy source of truth:
scripts/build-<brand>-audio.mjs(copy the noban one for a new brand). VO lines are keyed by act, written FOR THE EAR ("dot gg", not ".gg"), one line per act, terse. Music prompt describes the brand's sonic character. - Run it with
--project <product>(music takes 1-3 min). Check every line's duration fits its act; trim TEXT if not, re-run with --force. - Merge with
--project <product>, then render into the product workspace using its public directory. Picture and sound consume the same shot plan; explicitaudioRefmaps voice independently of visual source IDs, whilenullmeans no narration. - Listen-proof: verify the mp4 has an audio stream (ffprobe), then SEND the video —
audio is approved by ear, by the user. Ducking feel (base 0.35 / duck 0.12) is
tunable in
studio/src/lib/audioMix.tsif redlined.
Recipe B: standalone audio
- Shared-repo guard per marketing-studio. The feeder code lives in the engine, but all generated audio lives in the product workspace.
- Music:
node feeders/audio/client.mjs music --project <product> --brand <brand> --prompt "<sonic character>" --length-ms <n> --out <product-output>.mp3(exact-length, commercially licensed on paid plans; 3s-120s). Voiceover: write{lines: [{id, text}]}to a temp JSON (text written for the ear), then run the voice feeder with--project <product> --brand <brand>and a product-owned output. Durations print as... OK: <name> <ms>ms;probe --file <mp3>re-measures. - Listen-proof: SEND the product-owned mp3(s) to the user. Machine loudness, beat, and cue reports remain incomplete until a human listens.
