remix_stream.h File Reference

Detailed Description

The abstraction of multichannel audio data in libremix is known as a stream.

A stream may consist of multiple channels, each of which can consist of an arbitrary number of sparsely placed chunks of raw audio data. The channels are named with spatial names such as LEFT, RIGHT and CENTRE as required for common home, studio and theatre environments.

Generic routines are provided for mixing, multiplying and blending streams of data.
