From what I understand, and can corroborate from my own experience, there is an annoying, often audible glitch that occurs due to periodically dropped sequences of 32 (?) frames during recording. It's subtle, but quite audible when it falls in a place on the waveform resulting in a very large difference between the remaining segments.

I'm currently working on software that will automatically remove some of the more audible resulting clicks, but I would much rather work on firmware that doesn't drop any samples in the first place!
