OPTIMOD-PC INTRODUCTION
1-3
Without Optimod-PC processing, audio can sound dull, thin, or inconsistent in any
combination. Optimod-PC’s multiband processing automatically levels and re-
equalizes its input to the “major-market” standards expected by the mass audience.
Broadcasters have known for decades that this polished, produced sound attracts
and holds listeners.
You can expect a considerable increase in loudness from Optimod-PC processing by
comparison to unprocessed audio (except for audio from recently mastered CDs,
which are often overprocessed in mastering). Broadcasters generally believe that
loudness relative to other stations attracts an audience that perceives the station as
being more powerful than its competition. We expect that the same subliminal psy-
chology will hold in netcasting too.
Figure 1-1 shows a 15-minute snapshot of program audio as it emerged from the on-
air mixer of a major Los Angeles radio station. Source material included music,
speech, and commercials. Notice the large inconsistency in peak and average level
between one program source and the next. Figure 1-2 shows the same material af-
ter being processed through OPTIMOD-PC, using the
G
REGG
preset. Notice that pro-
gram levels are now consistent from source to source
