Canonical short-form-ad audio mix in one FFmpeg pass. VO loudnorm + 3.0× per-clip + 2.0× mix, music 0.13 base + apad+afade, sidechain compress 20:1 @ 0.01, climax line +20%, optional video-to-music duration sync. Replaces the reactive multi-round tuning that cost v03 6+ passes.

> **Superseded:** the video kit now does this with the audio-mix part, version 1.0.1 and the sound-layer part, version 1.0.4, in the parts folder of this repository. Its mix mode is the audio-mix step (voice, a ducked bed and timed effects) and its finish mode is the sound layer, which levels every video to -14 LUFS with the true peak at or below -1 dBTP. This atom stays, unchanged in behaviour, for skills outside the kit until they move; its scripts still run.

# mix-master

## Purpose

The v03 Ironman LEARNINGS describe 6+ tuning rounds because no default mix protocol existed: round 1 music too loud, round 2 VO too quiet, round 3 Whisper mis-transcribed, round 4 sidechain ratio finally right, round 5 music ended too early, round 6 climax sat at the same loudness as the rest.

This atom encodes the protocol that landed and ships it as the default. Operators tune by flag; they don't redesign the chain.

## Inputs

- `--video <path>` — video file with no audio (or whose audio gets dropped) (required)
- `--vo <path,path,...>` — comma-separated list of per-scene VO mp3s in scene order (required)
