I suspect your Raspberry Pi is just running out of memory. If so, you can try closing other applications that you have running on your Pi. I don't think the Pi allows for its memory to be upgraded. I can't think of any good tips to lessen the amount of memory used the ListPlot3D (other than perhaps subsampling your spectroGramData before feeding it to ListPlot3D).

I used another Pi with not so many applications running. It does seem that for what I am trying to do, 1 second of audio is about the limit, which is actually is not too much of a limitation. :-) In fact, I am impressed that I can do this with a Raspberry Pi and Mathematica! Some results from my Pi...
