NAB 2011 is the venue for Linear Acoustic’s unveiling of the AERO.calm Coded Audio Loudness Manager. The new processor is described as the culmination of years of research into loudness control and audio and metadata processing.
A hybrid of sophisticated multiband audio analysis and metadata control, AERO.calm allows audio to be processed in a consumer-reversible manner, permanently for noncritical material, or anywhere in between. Smooth and consistent by default, 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.
“AERO.calm is the only television audio processor capable of controlling loudness and dynamic range without affecting the original content,” said 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 programme producers.”
