How Dolby Advanced Audio v2 Works

Sound from a laptop or desktop computer has inherent audio problems. These originate in both the audio quality of the source material (a video clip, for instance) and in the playback process.

Typical problems with audio content include:

Content not produced in surround sound

Dull sound and unintelligible dialogue on user-generated content

Wildly varying volume levels from one piece of content to the next

The PCs themselves are limited by physical designs that dictate small speakers and underpowered amplifiers. Problems include:

Irregular frequency response with no highs or lows

Unnatural, colored sound

Volume levels typically not loud enough

Distortion and annoying mechanical vibrations when sound is turned up

Dolby Advanced Audio v2 Solves Audio Problems

Designed into a PC, Dolby Advanced Audio v2 first applies processing that fixes any problems with the source material. It then fixes playback problems by compensating for both general and specific mechanical constraints. This processing ensures that our unique custom-tuning is designed for each and every computer model that includes Dolby Advanced Audio v2. Dolby Advanced Audio v2 technologies:

Use our latest and most advanced algorithms

Leverage our four-plus decades of research into how people perceive sound

Match human audio perception

Are built on a common processing framework to share resources

Work intelligently together
