Gone will be the days of relaxing on the couch while watching TV, only to frantically jump up and turn the volume down when a particularly loud commercial comes on. That’s what Dolby hopes to avoid with a system introduced at CES last week, called Dolby Volume. The system introduces technology to equalize the volume accross TV channels, programs, and commercials.
Dolby says that the goal of Dolby Volume’s aim is to deliver consistent volume levels by modeling how “humans perceive audio” to eliminate variable loudness in the audio stream. Dolby claims that the system does this automatically without any type of user intervention (aside from the initial setup). During the demonstration, Dolby’s engineers said that the adjustments will be non-linear and that they will be able to process all types of audio streams without worrying about sampling rates. The system will be able to handle up to a 30dB in reduction or amplification. No word on what happens when watching an action movie or TV show with explosions or or other sudden noises that are meant to be loud and startling.
