The new technology has been designed to help users watch content late at night without disturbing those that are sleeping or having to play the system at low levels. The new technology as been named LFC or low-frequency containment and will show up as a feature in AV receivers from Onkyo, Denon, and Marantz by the end of the year.
LFC limits bass output to help combat the ability of bass waves below 200Hz to penetrate walls. The technology takes its cues from volume changes in the program material and artificially synthesizes harmonic tones to fill the gap of the lost bass tones.
This is the first of three new processing technologies that Audyssey plans to announce this year.
