Arkonnekt

Arkonnekt is a simple AudioUnit host for Mac OS X which allows you to easily create arbitrary graphs of audio effects and play a sample through the effects chain to any output on your computer. Arkonnekt is deliberately simple. There are no explicit concepts of busses, or sidechains, only nodes with inputs and outputs. By connecting these nodes in unique ways, an endless variety of effects can be achieved.

In addition, Arkonnekt eliminates the idea of mixers. Instead of complex mixer units with sends, input levels and panners, a simple node which merges incoming connections, and splits outgoing connections is used. Combined with volume and panner units, very sophisticated mixer graphs can be created.
