Intel has worked with the industry to develop a new specification for integrated audio that is capable of delivering the features and high-end performance of an add-in audio card. Intel® High Definition Audio (Intel® HD Audio) is capable of playing back more channels at higher quality than previous integrated audio formats. In addition, Intel® High Definition Audio (Intel® HD Audio) has the technology needed to support the latest and greatest audio content.
By enabling enhanced usage models, Intel® High Definition Audio (Intel® HD Audio), available with the Intel® Express Chipsets, will also change how computer users interact with sound. The Challenge to Find Better Audio When Analog Codec '97 was initially developed, users were typically listening to only music and movies with stereo sound.
With the success of DVD movies encoded with Dolby Digital* and DTS* multi-channel audio formats, users have become accustomed to listening in full surround sound with anywhere from six to eight speakers. While Analog Codec '97 technology has struggled to keep pace with all these advancements, Intel® High Definition Audio (Intel® HD Audio) is designed specifically for the high-quality multi-channel audio experiences. Newer audio and video encoding and decoding algorithms also enable a higher-quality listening experience. More and more consumers are moving their computers into the living room or family room so they can enjoy digital music or movies throughout the house on state-of-the-art multi-channel audio systems or big screen TVs. With better speakers connected to their computers, the limitations of current computer sound subsystems, whether integrated or add-in, can degrade the overall digital experience.
Many consumers are also asking for the ability to play two different audio streams through their PC at the same time—perhaps classical music in the study and a movie in the living room. These demands cannot be met with previous audio solutions.
An Outstanding Audio Experience Intel® High Definition Audio (Intel® HD Audio) delivers significant improvements over previous generation integrated audio and sound cards. Intel® High Definition Audio (Intel® HD Audio) hardware is capable of delivering the support and sound quality for up to eight channels at 192 kHz/32-bit quality, while the Analog Codec '97 specification can only support six channels at 48 kHz/20-bit. In addition, Intel® High Definition Audio (Intel® HD Audio) is architected to prevent the occasional glitches or pops that other audio solutions can have by providing dedicated system bandwidth for critical audio functions.

Innovative Uses for the Digital Home Dolby Laboratories selected Intel® High Definition Audio (Intel® HD Audio) to bring Dolby-quality surround sound technologies to the PC as part of their recently announced PC Logo Program. The combination of these technologies marks an important milestone in delivering quality digital audio to consumers. Intel® High Definition Audio (Intel® HD Audio) is able to support all the Dolby technologies, including the latest Dolby Pro Logic* IIx, which makes it possible to enjoy older stereo content in 7.1 channel surround sound. Enhanced Features Intel HD Audio (Intel® HD Audio) also enables enhanced voice capture through the use of array microphones, giving users more accurate speech input. While other audio implementations have limited support for simple array microphones, Intel HD Audio (Intel® HD Audio) supports larger array microphones. By increasing the size of the array microphone, users get incredibly clean input through better noise cancellation and beam forming. This produces higher-quality input to voice recognition, voice over IP (VoIP), and other voice-driven activities.
