• Dolby Advanced Audio v2

    Dolby Advanced Audio v2 improves PC audio with technologies that maintain volume levels, prevent distortion, and even create a surround sound experience.

    Dolby Advanced Audio v2 Benefits

    • Authentic Dolby Surround Sound

      Dolby® Advanced Audio™ v2 converts your music and other two-channel (stereo) entertainment into 5.1-channel surround sound, and your 5.1-channel entertainment like movies into 7.1-channel sound.

    • Consistent Volume Levels

      The Volume Leveler feature in Dolby Advanced Audio v2 locks in your preferred volume level for more consistent listening.

    • Distortion-Free Performance

      Dolby Advanced Audio v2 optimizes audio performance for your specific PC model and lets you turn up the volume without distorting the sound.

    • Total Audio Control

      A ten-band graphic equalizer in Dolby Advanced Audio v2 provides you with complete control over your PC's audio profile.

    Experience sound to rival the other powerful features in your PC.

    A New Level of Audio Performance

    Your current PC may be faster and sleeker than its predecessor, but it probably doesn't sound any better. The small speakers and modest amplifier can do only so much for your music or the movies and TV shows you watch in your downtime.

    Dolby Advanced Audio v2 addresses the shortcomings of PC audio with technologies that provide crisp, clear surround sound over a PC's built-in speakers and improve the clarity of connected headphones, too.

    Dolby Advanced Audio v2 borrows from the pioneering work Dolby engineers have done in the cinema and the home theater. The result is a suite of technologies that PC makers can build directly into their products to elevate audio performance and provide you with a more enjoyable listening experience overall.

    The Challenge of PC Audio

    Understanding how Dolby Advanced Audio v2 works requires understanding the problems inherent in PC audio. These originate in both the quality of the source material and the playback process.

    Typical problems with sources include:

    • Dull sound and unintelligible dialogue on user-generated content
    • Wildly varying volume levels from one source to the next
    • Content not produced in surround sound

    The small speakers and underpowered amplifiers required to fit into the physical design of PCs create other problems. These include:

    • Irregular frequency response with no highs or lows
    • Unnatural, colored sound
    • Volume levels that are typically not loud enough
    • Distortion and annoying mechanical vibrations when sound is turned up

    The Dolby Advanced Audio v2 Solution

    Designed into a PC, Dolby Advanced Audio v2 first applies processing that fixes any problems with the source material. It then fixes playback issues by compensating for mechanical constraints of the PC itself.

    Because Dolby engineers custom-tune each PC model that includes Dolby Advanced Audio v2, the audio processing ensures that you enjoy optimal sound for the specific combination of speakers and amplifier in your PC.

    Dolby Advanced Audio v2 technologies:

    • Use our latest and most advanced algorithms
    • Draw on our extensive research into how people perceive sound
    • Match human audio perception
    • Are built on a common processing framework
    • Work together intelligently
