LM6 - Radar Loudness Meter / 5
EN
LM6/LM2 represents a quantum leap away from simply measuring audio level to
measuring perceived loudness. The old level method is responsible for unacceptable
level jumps in television, for music CDs getting increasingly distorted, and for different
audio formats and program genres becoming incompatible: Pristine music tracks from
the past don’t co-exist with new recordings, TV commercials don’t fit drama, classical
music or film and broadcast doesn’t match. The most fundamental audio issue of all
– control of loudness – every day makes millions of people adjust the volume control
over and over again.
LM6 is part of a universal and ITU standardized loudness control concept, whereby
audio may easily and consistently be measured and controlled at various stages of
production and distribution. LM6 works coherently together with other TC equipment,
or with equipment of other brands adhering to the same global standard. Follow the
guidelines given to allow audio produced for different purposes to be mixed, without
low dynamic range material such as commercials or pop CD’s always emerging the
loudest.
