Operating Basics

This section describes some of the audio control functions.

Dolby Advanced Audio provides a stunning listening experience from any 

pair of speakers or headphones. Adding a new level of realism to movies, 

music, and games, this is the quality audio customers have been missing 

from your computers.
Dolby Advanced Audio includes:

■

High-Frequency Enhancer: Analyzes and restores high frequencies lost 

during encoding. Works on any speaker for a higher level of audio than 

was previously possible.

■

Audio Optimization: Corrects common audio problems caused by 

laptop limitations for a better entertainment experience.

■

Natural Bass: Extends the bass response of any speakers by up to an 

octave.

■

Dolby Headphone: Enables personal surround sound using any set of 

headphones.
