Post subject:  Linux-Based Low-Latency Multichannel Audio System

Hi there,

Together with my professor, I've developed a multichannel audio system based on the AD1938 audio codec by Analog Devices and the BeagleBone Green (TI AM335X SoC).
The audio system offers 2 stereo inputs and 4 stereo outputs.
The whole project is based on open source software.
To demonstrate the possibilities of the audio system, I've created a surround delay effect with the open source C++ library DSPatch by Marcus Tomlinson.
Moreover I've created an automatic test based on GNU octave to evaluate the audio system characteristis, such as latency, THD+N, DNR, crosstalk and frequency-response.
