# Music & sound

Beat sync, scoring, loudness, stripping copyrighted music, voice cleanup.

- [Beat-sync cutting: cut on the beat, not on every beat](https://superduperai.co/library/beat-sync-cut-not-every-beat.md): A rule and an agent prompt for cutting to music from a list of beat timestamps: cuts land on beats, phrases get room to breathe, and the best shot is held through the hook.
- [Prompt for a music generator: a 30-second instrumental for a short](https://superduperai.co/library/generated-music-30s-track-brief-prompt.md): A brief in the shape music generation tools read: structure by seconds, BPM, three instruments, no vocals, a drop that lands on your hook cut, and an ending that stops instead of fading.
- [Live music in frame: one continuous audio span, picture cuts on top](https://superduperai.co/library/live-music-one-continuous-audio-span.md): When a band or a busker is in the shot, keep one unbroken stretch of that clip's audio under the whole scene and cut only the picture; cut the audio per shot and the beat restarts.
- [Level every chapter to -16 LUFS with ffmpeg loudnorm](https://superduperai.co/library/loudness-normalize-minus-16-lufs-ffmpeg.md): One ffmpeg line that brings a file to -16 LUFS integrated and -1.5 dBTP true peak without touching the video, the two-pass version for exact results, and the timestamp trap on upload.
- [Music brief: describe the track you need before you search for it](https://superduperai.co/library/music-brief-prompt-for-picking-a-track.md): A fill-in brief that names mood as harmony, a BPM range, genre, length and where the drop must land relative to your hook, so a library search or a composer returns something that fits the cut.
- [Score with a hole, not ducking, where something plays live](https://superduperai.co/library/score-hole-where-live-sound-plays.md): Cut the score to silence under live music, a laugh or a knock instead of ducking it; ducking is audible, a hole is not. The rule, the measured levels and the ffmpeg line.
- [Strip other people's music before upload with Demucs and ffmpeg](https://superduperai.co/library/strip-other-peoples-music-demucs.md): Car radio, shop speakers and festival stages trigger Content ID. Split the soundtrack into stems, find the music on drums plus bass, keep the voice, replace the music, rebuild audio only.
- [Voice cleanup checklist: room tone, de-ess, noise gate, in that order](https://superduperai.co/library/voice-cleanup-checklist-room-tone-deess-gate.md): Six passes that turn a phone or lav recording into a usable voice track, each with the ffmpeg filter and a starting parameter to adjust by ear, in the order that keeps the gate off word endings.
