You should talk to musicians about digital equipment. They talk about latency in terms of how far away the instrument feels. It’s wild, good musicians can describe latency on the order of low tens of ms. What’s crazy to me is how good they can get at adjusting. If 8 play a game like rock band, if I don’t adjust for video and audio latency, I just can’t play at all.

And it gets worse, since equipment gets chained. If you add more than a few ms to the wet channel, it accumulates and can be very problematic if you ever feed the wet back into the dry signal.
