[QUOTE="Karl Winkler, post: 34400, member: 255"] Re: Psychoacoustics I agree, but I meant "effect" in a different way, i.e. the "effect that it seemed not to come from the speakers". Hopefully that made sense. And Silas, True - it's never perfect. At the same time, there is some room for slop. Whichever source arrives first is the one that appears to the listener as "the original". It only has to be 2 or more milliseconds ahead of other copies. But for two sources to appear distinct in time to the listener, they must be 10 ms or more, usually 20 ms later, depending on how much transient information is in the sound. So you have the slop of between say 2 ms and 10 or 15 ms reasonably before you have problems. Thus, you can set up your system so that 80% of the audience is within that zone, and you're probably good. The other 20% may hear things as either "speakers first" or as distinct copies, depending on where they are. If the latter group is say 5%, well, I still think you're better off than if 100% of the audience hears the speakers first and doesn't localize the "original source" as coming from the stage. This may be a subtle thing, but as I mentioned before, I came to like it a lot and felt that it added something to (or, took something away from) the illusion of acoustic music - I was working with a big band.
