Windows XP builds on the digital audio and video capabilities of prior versions of Windows by supporting new devices and technologies and providing additional playback and storage options for digital media.
To support digital audio devices, Windows XP—like Windows 2000 before it—uses the Windows Driver Model (WDM) audio architecture, which enables the operating system to manage multiple audio streams simultaneously. And like both Windows 2000 and Windows Me, Windows XP also supports the Audio Codec ’97 (AC ’97) specification for digital audio, which defines a widely adopted audio architecture. Further, Windows XP supports digital audio on several bus types, including PCI, ISA, and Personal Computer Memory Card International Association (PCMCIA) buses, and on external USB and IEEE 1394 digital audio devices.
Windows XP includes several new technologies designed to enhance digital audio playback and recording, such as:
Multichannel audio output and playback of additional audio formats. Volume can be set for each speaker in a multichannel configuration.
Acoustic Echo Cancellation (AEC), a signal processing feature that reduces feedback, echo, and other ambient noise from an input channel. USB microphones in particular benefit from this technology.
Global Effects (GFX), which enhances USB audio support by allowing filter drivers to support devices such as USB array microphones.
