For the Love of Music: Loudness Normalization

Wild theories about level normalization "destroying sound" continue to reappear, as if decades of loudness normalization efforts have been for nothing. This article hopes to set the facts straight regarding loudness concepts, standards, and implementation. Loudness normalization not only tremendously improves the listening experience for consumers, but it is also an element in control of sound exposure and prevention of hearing loss.

Loudness processing and optimization is a requirement in broadcast services - radio and TV - but also in streaming services, from OTT to music streaming platforms. Typically, loudness monitoring is complemented with loudness optimization handled at the source file level and performed by a team of highly trained audio engineers, working 24/7 on powerful servers and workstation... Right? Angry Audio, the problem-solving company knows that's not the case and designed the Audio Chameleon C4 Livestream Audio Processor.

Controlling loudness levels is now easier than ever. The new LCn Loudness Correct from TC Electronic works either as a Pro Tools plug-in or as a complementary stand-alone version with watch folder capability for automatic batch-normalization of multiple audio files. LCn is available for stereo or 5.1 surround - LC2n and LC6n respectively.
