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.

Audio Full Surround 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.

Intel High Definition Audio (Intel HD Audio) hardware is capable of delivering the support and sound quality for up to eight channels at 192 kHz32-bit quality, while the Analog Codec 97 specification can only support six channels at 48 kHz20-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.

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.

Intel High Definition Audio (Intel HD Audio) features multi-streaming capabilities that give users the ability to send two or more different audio streams to different locations at the same time, from the same PC.

Audio Driver Is Expected

While the Microsoft driver is expected to support basic Intel High Definition Audio (Intel HD Audio) functions, codec vendors are expected to differentiate their solutions by offering enhanced Intel High Definition Audio (Intel HD Audio) solutions.

While other audio implementations have limited support for simple array microphones, Intel High Definition 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.

The computer can sense when a device is plugged into an audio jack, determine what kind of device it is, and change the port function if the device has been plugged into the wrong port.

For example, if a microphone is plugged into a speaker jack, the computer will recognize the error and will be able to change the jack to function as a microphone jack.

This is an important step in getting audio to a point where it just worksusers wont need to worry about getting the right device plugged into the right audio jack.

As one of the many new technologies introduced with the Intel 955X, 925, 915, and 910 Express Chipset family, and now the Intel 945 Express Chipset family, Intel HD Audio enhances the end-user experience and enables the convergence of digital entertainment for both PCs and consumer electronics (CE) products.
