AM6 - TRAILER AND COMMERCIAL METER
Radar Leq(M) meter for Cinema Production
Pro audio is moving decisively away from the peak level based normalization method
that has caused so much havoc with trailers in movie theaters. The new and better
mantra is to combine frequency weighting with an energy-integrated measure of sound,
or equivalent continuous sound level, abbreviated Leq, and the level regulation of
commercials and trailers in movie theaters is based on a measure of annoyance, also
knownasLeq(M).
TASA,MPAA,Dolby,DTSandotherswereinvolvedinthedefinitionofLeq(M),and
the principle has since been adopted in several countries. Today, movie trailers
and commercials are therefore generally under satisfactory control, though movies
themselves may sometimes be annoyingly loud.
Recognizing requests from many Pro Tools users producing audio for broadcast as well
asforcinema,anLeq(M)basedradarmeterisnowavailable:TheAM6.Theradar
epitomizes an intuitive and efficient way of visualizing loudness or annoyance over
time,whiletheintegratedLeq(M)numberindicatesthestatusoftheentiretraileror
commercial with regard to regulatory limits.
