How long is the delay? I'm running Win7, but I didn't have the WASAPI plugin (just now picked it up, thanks for the tip).
I've previously tried deliberately going for delay time as a cue, but no success--the way I was running it (foobar2000 plus ABX utility only) I couldn't find a delay--I've never had a 100% success.
OK, just now installed WASAPI and loaded it up.
I think I hear what you're talking about in the delay (haven't actually been able to get a positive result, though), but in any case I don't use continuous playback to A/B.
I set "Start" and "End" times, and uncheck the "keep playback position" box.
This allows me to directly compare one distinct musical segment in two versions, not different parts of the clip as we pass through the entire track while A/B-ing.
So I'll play, say, 'A' multiple times, stopping every time. Then I take a breath, and play 'B', and stop.
It's possible that there could also be a delay as well at the beginning of every playback restart, except that it sounds instantaneous to me--distinctly different from the continuous-playback skip that occurs when A/B-ing with the "Keep playback position" box checked.
In any case, now I can go back and try with WASAPI for the several comparisons, many thanks for the tip.
