Linear Acoustic CALMS Loudness Challenge
Linear Acoustic’s AERO.calm (Coded Audio Loudness Manager) will make its big debut at the NAB Show next week in Las Vegas. “AERO.calm is the only television audio processor capable of controlling loudness and dynamic range without affecting the original content,” says Tim Carroll, founder of Linear Acoustic. “Broadcasters can rest easy knowing they are legally compliant, bolstering ratings by satisfying viewers, and still preserving the captivating audio experience intended by program producers.”
Carroll says AERO.calm is the culmination of years of research into loudness control and audio and metadata processing. A hybrid of sophisticated multiband audio analysis and metadata control, audio can be processed in a consumer-reversible manner, permanently for noncritical material, or anywhere in between. He adds it is smooth and consistent by default and individual viewers can choose to hear the full range of the original content if they desire. Versions of AERO.calm are available to handle baseband AES/SDI audio, DVB-ASI, and transport stream over IP.
