Finally have audio capture working on beaglebone. The code requires a lot of cleaning up and optimization. Audio capture happens in realtime by programming one of the two PRUs (microcontrollers on the processor SoC).

Helpful links for getting this working:

1. pru-sdk

2. TI PRU Code Generation Tools

And some sample capture data.
