This is a semester project that investigates using single-board-computer devices ( like this bananapi or odroid ) connected via ethernet as inexpensive audio co-processing. ARM based single board devices can offer an open alternative to DSP based audio processing cards.

The DiauproPlugin can be compiled as an AudioUnit or VST plugin. It is a very simple implementation of a virtual synthesizer. It is monophonic. The VCO block produces a sine wave, the VCA block produces an envelope when a midi not is triggered. The VCO and VCA blocks can process audio locally in the plugin, or remotely on networked AudioProcessorNodes. The DiauproPlugin will browse the LAN Network for corresponding remote service via Bonjour/Zeroconf.

The AudioProcessorNode can be compiled and run on an OSX, Windows, or Linux device. It is specifically tested on Bananapi and Odroid devices running ubuntu. When running it registers it's available processing services via Bonjour/Zeroconf on the LAN Network. The DiauproPlugin will connect automatically upon finding the service in the Network.

The documentation can be built using the following command:

$ python /Documentation/build.py

this will produce PDF and HTML files in German and English
