I emailed [EMAIL PROTECTED] and got the below response (hopefully Tom
Pepper doesn't mind me sharing his response). However, just so it's clear
I was talking aboot recording an fm radio station or a mixer hooked up to
cd players and turntables from my line-in and getting to choose my sample
rate. I wasn't going to resample CD rips.

lots of soundcards don't have the timing right for samplerates not based
around 11, because most soundcards have a 11khz clock and not a 16khz clock.
besides, most source audio is at 44kHz anyway, and the conversion to 16 or
32 takes an initial conversion to the nearest multiple of 11, so there's no
real benefit to using 16/32.
