Dialogue Stem Loudness Checker
Measure a dialogue stem against the −27 LUFS region used as a dialog anchor in OTT mixing, with true peak ≤ −2 dBTP.
Running the BS.1770 measurement on a solo'd dialogue stem approximates a dialog-gated measurement of the full mix. It's a standard pre-delivery trick: stem reads −27 ±2 → the dialog-anchored programme measurement will be close.
