A square / rectangular shaped audio glitch appeared while we were recording a book. (See pic). When we heard it back, it sounded like digital distortion. I would love to understand what caused this and what I could do to prevent this from happening in the future. We are using a MOTU and a RODE mic. Thank you!

Hard to say - but I can tell you a bit about it... it's not just present in the glitch, for a start. If you amplify what looks like silence just before it (about 45dB) you'll find that a very slightly modified version of it is going on there too:

This somewhat points the finger of suspicion at your sound device. What MOTU is it, and is this a 'normal' Rode mic? I've heard similar bursts of what sounds like similar interference from radio mics...

A bit of audio of it would be more use than just looking at the waveform...
