Audio stream input output
ASIO (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 synchronization 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.
