When the sound card uses a custom driver for use with the system supplied port class driver PortCls.sys or implements a mini-driver for use with the streaming class driver, applications can bypass the KMixer completely and use the kernel streaming interfaces instead to directly interact with audio driver and reduce latency. Windows 98 includes ...
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:
Released around 1984, the original MPU-401 was an external breakout box providing MIDI IN/MIDI OUT/MIDI THRU/TAPE IN/TAPE OUT/MIDI SYNC connectors, for use with a separately-sold interface card/cartridge ("MPU-401 interface kit") inserted into a computer system. For this setup, the following "interface kits" were made: MIF-APL: For the Apple II [2]
The USB specification defines a standard interface, the USB audio device class, allowing a single driver to work with the various USB sound devices and interfaces on the market. Mac OS X, Windows, and Linux support this standard. However, some USB sound cards do not conform to the standard and require proprietary drivers from the manufacturer.
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.
Advanced Linux Sound Architecture (ALSA) – the standard Linux sound-driver interface; Scanner Access Now Easy (SANE) – a public-domain interface to raster-image scanner-hardware; Installable File System (IFS) – a filesystem API for IBM OS/2 and Microsoft Windows NT; Open Data-Link Interface (ODI) – network card API similar to NDIS ...
