click1.wavZooming in on the audio it looks like this:
That's three tracks of audio and one track of nothing, showing a single sample out of place.
I made some more samples:
clicks-verylong.wavLooking at these I thought I saw a pattern: for a few samples in a row the sign is reversed. It's hard to be sure, though, with this setup. So I tried a higher pitch sine wave and put the mics at different distances so they'd have phase shifts relative to each other. Sure enough, some glitch is flipping the polarity:
high.wav(On track 1 two samples are flipped while on tracks 2 and 3 three are. On all the others I looked at the same number of samples were off on every track.)
What would do this? I don't know. I've posted on the presonus forum; we'll see what they say.
 While I noticed them whatever I was doing, I decided to make a test setup so I could really see what was happening. I had my phone generate a sine wave and pointed three microphones at it. I restarted my computer (a mid 2011 13" macbook air on 10.8) so it would be fresh, started VSL (1.2.5296), started Audacity , and set it to record all 8 tracks.
 I also got these clicks when using Presonus' Studio One, but I'm more familiar with Audacity so it was easier to take screenshots and make clips there.
