Another goal of UAA is to provide better support for multi-channel audio in Windows so that, for example, multi-channel WMA Pro audio streams can be played without special driver support. UAA is intended to be a complete replacement for developing WDM Audio Drivers; however, in some cases it may be necessary for an otherwise UAA-compliant audio ...
The Service Pack 3 update to Windows XP and all later versions of Windows (from Vista onwards) included the Universal Audio Architecture (UAA) class driver, which supported audio devices built to HD Audio's specifications. Retrospective UAA drivers were also built for Windows 2000, Server 2003 and XP Service Pack 1/2.
Audio Stream Input/Output (ASIO) is a computer audio interface driver protocol for digital audio specified by Steinberg, providing high data throughput, synchronization, and low latency between a software application and a computer's audio interface or sound card.
KMixer is the Kernel Audio Mixer driver, a part of WDM Audio in Windows 98 to Windows XP which handles the mixing of multiple sound buffers into an output. The tasks performed by KMixer.sys: Mixing multiple PCM audio streams; Format, bit-depth (also known as word-length) and sample-rate conversion; Speaker configuration and channel mapping
For this it assumes to have exclusive access to the kernel's audio sub-system. The scheduling requirements of JACK to achieve sufficiently low latencies were one of the driving forces behind the real-time optimization effort for the Linux kernel 2.6 series, [ 8 ] [ 9 ] whose initial latency performance had been disappointing compared to the ...
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.
In computing, the Windows Driver Model (WDM) – also known at one point as the Win32 Driver Model – is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1, as well as the Windows NT Driver Model.
Windows Sound System (WSS) is a sound card specification developed by Microsoft, released at the end of 1992 for Windows 3.1. It was sold as a bundle which included an ISA sound card, a microphone , a pair of headphones and a software package.
