TC Electronic LM5 - Loudness Radar Meter (TDM)

A fundamental issue for broadcasters is how to control the volume of disparate media, be it pristine music tracks from the past that have great dynamic range, new recordings that are "flat-lined" and loud, or TV commercials blaring out during drama broadcast breaks. This issue (control of loudness) makes millions of people adjust the volume control over and over again, every day.

LM5 from tc electronic 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. The software can instantly display loudness, loudness history and true-peak level derived from this international standard.

LM5 is suitable for use in music, post production, broadcast and film, and offers a more coherent way of managing level and avoiding distortion when compared to present methods still used in music production today. The loudness meter may be used in conjunction with existing PPM and VU meters, and also greatly increases the usability of Dolby's LM100 by providing running status, and a standardized indication of dialog, as well as non-dialog program.
