Using an FPGA to sample audio from multiple digital microphones and perform correlation, then visualise it on a PC. Presently, this repository is a hodgepodge of things including source files, executables, libraries and build scripts. I have tried to stay cross-platform, but everything so far only has been made to compile on OSX.
Sources used
I have used OpenGL C++ code from the LearnOpenGL tutorial series (specifically, tutorial 4.1 from section 1). I got the serial connection stuff from a question on stackoverflow :)
The Ethernet core is from LiteEth, it is an independently synthesized core using the gen.py script in that codebase.

Questions
How big is the Pdb PCB?
It measures 77.5 × 85.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pdb use?
22 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pdb KiCad files?
From the cbrinkerink/audio-interferometer repository on GitHub, at the commit this page was made from: the board is power distribution board/v1/pdb.kicad_pcb and its schematic power distribution board/breakoutboard/pdb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pdb design in my own project?
Its repository states no licence, so its author keeps all rights: ask cbrinkerink before reusing the design.
