Music, sound effects and mixing for drawn-by-code videos. Use it when choosing or cutting music, syncing the animation to the beat, placing sound effects (sfx) or generating new ones with ElevenLabs, and when adding the audio to the MP4.
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
# Sound The video is cut **to the music**, not the other way round: tempo first, cuts after. ## Music - Find the BPM and the first beat (`beatOffset`). At 120 BPM one beat = 0.5 s and a 4-beat bar = 2 s. Declare `bpm` and `beatOffset` in the scene. - If the track doesn't fit the duration, cut it by bars with ffmpeg: soft intro → strong entry → groove → the intro returns → final hit. - Leave 1.5–2.5 s at the end to read the closing line. - Licenses: Pixabay allows commercial use without attribution, but **not redistributing the track on its own**; don't commit it to the repo (do commit the cutting script). If YouTube claims it via Content ID, dispute it with the license. ### Synthesized music (license-free) If there is no track, it can be generated with code: `sandbox/2026-09-24-exquisite-corpse/music.mjs` writes a WAV with kick, snare, hi-hat, bass, sitar and a filtered pad, and changes texture at the same seconds as the scene's segments. It is deterministic, so the `.wav` is not committed: it is regenerated. Without listening to it, check it with the waveform (`ffmpeg -i mix.wav -filter_complex showwavespic=s=1600x240 -frames:v 1 wave.png`) and …

How to install
mdr add illodev/drawn-by-code/sound@sha256:2fb806acfffb36d9The line at the top of this page pins the label git:20261002.7d0e422, 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.
