af_resample.c has a 8000 Hz check but only for the output side which
stays constant when changing playback speed. I didn't notice any obvious
failure when testing it with sane values outside that range. The
"inexact frequency conversion" mode fails with extremely slow playback
speeds below 1/100 (it creates a filter which converts 0 input at a
time).
