Universal Audio Architecture

The Universal Audio Architecture (Universal Audio Architecture - UAA) is an initiative by Microsoft back to the year of 2002. Attempts were made to establish a standardization approach for the hardware and driver class architectures of the audio devices in modern Microsoft Windows operating systems. Three different audio device classes were supported as standard: USB , IEEE 1394 (also known as Apple FireWire or Sony iLink) and Intel High Definition Audio , which supports PCI and PCI-Express .
