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). -- Doug Lee dgl@xxxxxxxx http://www.dlee.org "It is not the mountain in the distance which makes you want to stop walking; but the grain of sand in your shoe." --Anon _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
