Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.

Intel started shipping the initial I/O Controller Hub support in 1999, and it wasn't until public shaming [1] in 2000, that most PC OEMs started shipping AC'97 audio as the default. In 2004, Intel released Intel High Definition Audio (HD Audio) which is a successor that is not backward compatible with AC'97. [ 2 ]
The A50p had an Intel Pentium 4 2.8 GHz Processor, 256 MB PC2700 DDR Memory, 40 GB 7,200 RPM Hard Drive, 48x CD-ROM Optical Drive, SoundMAX Cadenza (AC'97) Audio, Intel Extreme 2 Integrated Graphics with 64 MB of Shared Memory, a 10/100 Ethernet Port, and six USB 2.0 Ports. [17] The A50p was called a "high-end consumer PC" by PC Magazine. [18]
Intel Integrated Performance Primitives (Intel IPP) is an extensive library of ready-to-use, domain-specific functions that are highly optimized for diverse Intel architectures. Its royalty-free APIs help developers take advantage of single instruction, multiple data (SIMD) instructions.
The Miles Sound System was used in its history by over 7,000 video games across 18 platforms. [4] Computer Gaming World stated in 1994 that "Many of the game publishers have decided to support only those sound cards which are supported by the Miles drivers", especially the Sound Blaster.
It is, therefore, generally possible to have an entirely error-free digital audio system in which no noise or distortion is introduced between conversion to digital format and conversion back to analog. [a] A digital audio signal may be encoded for correction of any errors that might occur in the storage or transmission of the signal.
Intel's first IA-32 SIMD effort was the MMX instruction set. MMX had two main problems: it re-used existing x87 floating-point registers making the CPUs unable to work on both floating-point and SIMD data at the same time, and it only worked on integers. SSE floating-point instructions operate on a new independent register set, the XMM ...
