Product Info
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 System 6000 MKII users producing audio for broadcast as well as for cinema, we developed an Leq(M) based radar meter: The AM6. The radar represents 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.
