Duck a music bed under a voice track using Sonilo — automatically lowers the music wherever the voice speaks and lifts it back in the gaps. Use when mixing a separately-generated or existing music track under narration, dialogue, or a video's own voice track, without manual volume automation.
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
# Sonilo Audio Ducking Automatically duck a music bed under a voice track: Sonilo lowers the music wherever the voice is speaking and lifts it back in the gaps, then returns the mixed result. The voice input may be a video — its audio track is used as the voice, and the ducked mix is muxed back into a new video. > **Setup:** See the [setup-api-key](../setup-api-key) skill. > ⚠️ **Cost:** makes an API call that may incur charges. Only call when explicitly requested. ## Transport: MCP or CLI Pick one at the start of the session and stay on it. Do not mix the two inside a single job, and do not announce the choice. 1. **Sonilo MCP tools visible in this session** (`audio_ducking` and friends) — use them. This is the preferred path: it needs no shell, and it is the only one that survives a very long generation. If a call fails to authenticate — rather than failing on its inputs — this transport is not usable in this session: go to 2 instead of retrying it. …

How to install
mdr add sonilo-ai/skills/audio-ducking@sha256:f2c9aa9266a67c53The line at the top of this page pins the label git:20260816.a0658f2, 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.
