> castanets and short clicks I was doing just this experiment three days ago. I have a new audio interface, and used audacity to try to establish its round-trip delay. I created a rhythm track using a click sound, connected one channel's playback to an input, and recorded it. The latency was about 35.1 ms. Audacity (the 2.x series) allows adjustment of latency compensation in whole milliseconds. Edit: I set the latency adjustment for -35 ms so there was only the 0.1-ish residual latency. Playing one channel of the original track and the recording together (after adjusting the channel balance for equal loudness) was quite disconcerting.
