The mics are probably cheap but 16x ADC in decent quality with decent power supply and low time offset between channels? How much is a 16chn audio interface with 16 mic preamps these days?

It can be done w/o phase locked ADCs :D it just takes... More Cleverness.

I made a 16 mic array out of a bunch of trash-picked and cheap 4ch ADCs.

I see they have a XMOS 200 chip on there maybe they do some DSP magic with that?
