Intel High Definition Audio. Realtek ALC 882 HD Audio Codec. 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. [ 1]
Universal Audio Architecture (UAA) is an initiative unveiled in 2002 by Microsoft to standardize the hardware and class driver architecture for audio devices in modern Microsoft Windows operating systems. Three classes of audio devices are supported by default: USB, IEEE 1394 ( FireWire ), and Intel High Definition Audio, which supports PCI and ...
High-resolution audio. High-resolution audio ( high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD Audio.
HD Audio support in the 1xx3 improved through the chipset's life with several revisions. The DD and CC versions of the chipset both added full 7.1 HD-audio support to the chipset. The 1073 players all built on a common SDK (firmware+OS) provided by Realtek. This meant that they were all essentially similar in performance and interface.
AC'97 ( Audio Codec '97; also MC'97 for Modem Codec '97) is an audio codec standard developed by Intel Architecture Labs and various codec manufacturers in 1997. The standard was used in motherboards, modems, and sound cards . The specification covers two types of components, and the AC-Link digital interface between them: an AC'97 digital ...

In hardware, audio codec refers to a single device that encodes analog audio as digital signals and decodes digital back into analog. In other words, it contains both an analog-to-digital converter (ADC) and digital-to-analog converter (DAC) running off the same clock signal. This is used in sound cards that support both audio in and out, for ...
A PC speaker is a loudspeaker built into some IBM PC compatible computers. The first IBM Personal Computer, model 5150, employed a standard 2.25 inch magnetic driven (dynamic) speaker. [ 1] More recent computers use a tiny moving-iron or piezo speaker instead. [ 2] The speaker allows software and firmware to provide auditory feedback to a user ...
