Hacking Behringers Ultranet for a FPGA-based DIY-Audiomixer

In this episode I bring a broken Behringer P16-I back to life to build a FPGA-based audiomixer.

For this I'm using an Arduino MKR Vidor 4000 board with a SAMD21 microcontroller and an Intel Cyclone 10LP FPGA for the signal-processing. The audio-output to the analog world is done using a SPDIF adapter as well as a PDM-based DAC.

The whole project can be found on GitHub: https://github.com/xn--nding-jua/UltranetReceiver
