Here is a hypothesis: the record software does not correctly handle 32
bits per sample, and stores it as 16 bits per sample at double the rate.
I have tried converting the file with sndfile-convert to 16 and 24 bit
formats, that did not correct the behavior. Maybe I can force some
conversion with SoX. I'll play around with it when I get time to see if
that gives some better idea of what is wrong.
