When I listened to the Trinnov demo recording of the Tuba Mirum from Mozart's Requiem, I noticed this effect: the transients (e.g. sibyllants) of the singers were in a different place from the rest of their voices.

Re: [Sursound] Chasing flies with ambisoinics?
Okay, understood. In the course of thinking about this, I've come to the idea that maybe the problem is with the whole concept of spreading like this. When we localise a sound source, there's a lot of information in the transients, which will, of course, have a different spectral signature to the more stead state parts of the sound. The likelihood is therefore that the transients will be panned differently which will, in turn, make for inconsistent imaging, which would explain what I've been hearing with mgspreadpan.

Re: [Sursound] Catching the same fly twice (and a curious question)
Interesting - must be an aspect of the cocktail effect ...
