Bridge

Mix bridge

Stem sheet and loudness targets for the mix stage. The hierarchy set on /audio is law — the mix realises it, it does not renegotiate it.

Stem sheet (CSV)
One row per level of the audio ladder, with the delivery target.

Handoff

Out: Stem sheet: VO, primary SFX, music bed, ambience — split at the hierarchy boundaries.
Targets: Dialogue anchor −16 LUFS short-form, −23 LUFS broadcast; true peak −1 dBTP.
Back: Printed stems plus a mixdown matched to the picture lock.
Gate: Loudness audit runs before the rubric; a failing mix blocks master export.
