Audyssey Attacks TV Volume

The company has updated its Dynamic Volume technology to be more TV-centric.


Have you ever been blown out of your seat by TV commercials? Of course you have. Everyone knows the pain of watching a low-talking TV show, sporting event, movie, or other program, only to be blown out by ads.

In fact, it’s gotten so bad that the Commercial Advertisement Loudness Mitigation (CALM) Act will go into effect at the end of this year. Kicking off on December 31, 2011, the law was specifically designed to eliminate those loud commercials — something that Audyssey’s Dynamic Volume was previously tackling.

Instead of retiring the technology, Audyssey just announced plans to make Dynamic Volume TV, a new audio processing technology that will take the CALM Act one step further, by addressing other sound artifacts in television.

“Solutions that focused on volume spikes are no longer needed because The CALM Act fixes that problem. In fact, spike methods can actually introduce artifacts, such as pumping when watching movies or TV shows because they only react to sudden changes,” said Chris Kyriakakis, Audyssey’s CTO. “With Dynamic Volume TV we focused on a method that precisely matches the reaction time to the changes in the content for totally automated volume control.”

Based on human reaction modeling, Audyssey says that Dynamic Volume TV can detect the rate volume changes happen and adjust accordingly. It looks at dialogue and background noise, promising a better overall TV experience.

TVs with Dynamic Volume TV are expected to launch in early 2012.
