Balance sound in a BashCut edit: the mix measured by role, gain, fades, a fixed music bed under the voice, SFX at cuts, licensed music and SFX found, loudness per output. Triggers: "trộn âm thanh", "cân âm lượng", "nhạc to quá", "thêm sfx", "tìm nhạc", "nhạc không bản quyền", "meme sound", "audio mix".
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 mix in BashCut
You cannot listen: measure, change, measure again, and report the numbers.
## Tools
| Need | How |
|---|---|
| Clip level, fades, mute | Level: `clip volume <item> --db -4 --base-rev last` (`--items a,b` for several; linked sound follows), never `timeline apply` for it. Fades and mute: `setProperties` `fadeIn`/`fadeOut` (frames), `muted`; layer: `layers set --muted on` |
| Volume over time (swell at a drop, dip for one line) | `clip keyframe --property volume` (dB) on audio items or clips with linked sound; replaces `volumeDb`, stacks with fades and ducking |
| Music under speech | **Fixed bed first**: one level from the measured voice, `clip volume <bed> --db D --base-rev last`, ducking off (`setTrackProperties` `{"duckingEnabled": false}`). A `plan.cut` `music` without `duck` does this on apply (`underVoiceDb`, default 16; the result reports `voiceLUFS`, `musicLUFS`, `volumeDb`) |

How to install
mdr add dongnguyenvie/bashcut-agent-kit/audio-mix@sha256:85ebcb3d8dacef5aThe line at the top of this page pins the label git:20261018.620bb38, 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.
