That may be when I found myself defending "stretch" for its ability to let me skim vast quantities of audio
at very high speeds (20x - 50x normal) with enough remaining signal for me to detect number and nature of
speakers, types of background sound, etc... at a time when someone was just about to toss out "stretch"
because "tempo" has cleaner results at relatively low variations from 1::1.

I am forever grateful to the SoX devs for keeping the "stretch" effect.

As for "filter", vs "sinc": I think "sinc" was meant to replace "filter," but there is a long SoX sample
command line under "mcompand" in the man page that uses "filter" and is thus no longer directly usable. I
found that long command useful enough to add, in a SoX wrapper I call Audir, an "fm" pseudo effect that
tries to implement it. (I actually have "fmr" and "fmb" pseudo effects, for radio and broadcast signal
variants from that page).
