mkt,
ok, i understand which delay you’re talking about now 🙂 well, your explanations make sense, but 80ms of delay is so short that if you hear a signal and the same signal delayed by 80ms, they sound so close to each other that it’s almost instantaneous.
whereas when you call someone which is in front of you (that’s stupid, but just for the experiment), the difference between the natural sound and the MS sound is more like 500ms to 1000ms.
