Further testing reveals that there *is* a problem with importing 24 bit .wav 
files.  I used arecord and a tone generator to create short test files with 
16, 24, and 32 bit resolutions.  I was able to import the 16 and 32 bit 
files, but the 24 bit file became silent when imported.  

I'll report the 24 bit thing as a bug, unless somebody has some insight into 
the matter.

I'm also going to need some kind of utility to convert my 24-bit files to 32.  

Oddly, I also somehow got two sets of clips from the 32 bit files.  Possibly 
I double-clicked the Import button, or???
