What is *ASIO Interface Technology?
*ASIO is a trademark of Steinberg Media Technologies GmbH
ASIO provides an interface between your audio application and the sound card, and stands for: Audio Stream Input/Output. It was developed by Steinberg Media Technologies and helps manufacturers and developers to create hardware and driver software which extend the personal computer's audio connectivity to meet the needs of musicians and audio engineers. ASIO offers a relatively simple way of accessing multiple audio inputs and outputs. The Audio Stream I/O API addresses the areas of efficient audio processing, high data throughput, synchronization, low latency and extensibility on the audio hardware side. The interface is not bound to any fixed number of input and output channels, and provides a constant streaming model. Here is software for testing your ASIO interface: The ASIO Audio test signal generator.
