Audio stream input output
From Free net encyclopedia
Audio Stream Input Output is a protocol for low-latency digital audio specified by Steinberg.
ASIO provides an interface between an application and the sound card. Whereas Microsoft's DirectSound is typically for stereo input and output for consumers, ASIO provides for the needs of musicians and sound engineers. ASIO offers a relatively simple way of accessing multiple audio inputs and outputs independently. It also provides for the syncronization of input with output in a way that is not possible with DirectSound, allowing recording studios to process their audio via software on the computer instead of using thousands of dollars worth of separate equipment. Its main strength relies in its method of bypassing the inherently high latency of Operating system audio mixing Kernels, allowing direct, high speed communication with audio hardware.
The development kit (SDK) is available for download, and is supported by a number of soundcard drivers, including M-Audio and the kX Project.
