Loudness is a measure of the overall perceived amplitude of a track. It is related to mix level only in so much

as it is in line with how comfortable your mix is at a particular level. In broadcast, it is used to ensure that

different programs are perceived to be at the same volume, and therefore, a consumer would not be

reaching for the remote between shows. In stereo music, it has been used to match between tracks in a

similar but more elegant manner on streaming services.


Version 3.4 of the Dolby Atmos Production Suite and Mastering Suite provide both realtime and offline integrated loudness measurement tools.
