an AC'97 digital controller (DC97), which is typically built into the southbridge of the chipset, and; an AC'97 audio and/or modem codec, available from several vendors, which contains the analog components of the architecture. AC'97 defines a high-quality, 16- or 24-bit audio architecture with 5.1 surround sound support for the PC.
Notable Realtek products include 10/100M Ethernet controllers (with a global market share of 70% as of 2003) and audio codecs (AC'97 and Intel HD Audio), where Realtek had a 50% market share in 2003 and a 60% market share in 2004, primarily concentrated in the integrated OEM on-board audio market-segment.

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]
Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
Hardware audio codecs send and receive digital data using buses such as AC'97, SoundWire, [5] I²S, SPI, I²C, etc. Most commonly the digital data is linear PCM, and this is the only format that most codecs support, but some legacy codecs support other formats such as G.711 for telephony.
K-Lite Mega Codec Pack was chosen as a Softpedia Pick.

Includes 64-voice wavetable synthesizer (total 73 concurrent audio streams supported), interface to AC'97 codec, S/PDIF output, Dolby AC-3 decoder. [3] YMF738: Integrated Sensaura 3D audio, AC'97 2.1 interface. [4] YMF740C (DS-1L): Based on YMF724, but includes only 32-voice wavetable synthesizer (total 41 concurrent audio streams supported).
The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint.
