ARSC is a cross platform, open-source, audio I/O Application Programming Interface (API). With it you can create simple audio programs in a variety of languages and on several platforms. ARSC is geared toward audio research applications, but is not limited by such.
ARSC provides a robust set of functions for recording and/or playing sound. Mixing is possible using a simple callback function. Example programs are provided that show how to use ARSC in the context of different languages.
