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

Hi Dave, This magnification effect has been reported many times. I wonder how much it has to do with playing back at too high levels. We do associate LF energy and size. Too much of it and the source 'must be' big. That's certainly important - kind of the other end of the scale of quite

Thats pretty similar to an example I heard the other day. A composer had split the sound of a cello into different frequency bands and dispersed them around a lot of loudspeakers (in a line if I remember correctly) each one playing a different frequency - imagine his dissapointment when the human

This is also something I've been wondering about and trying to achieve in sound installations. A fly landed on a microphone once when I was recording in the jungle and when played back it sort of worked - sort of - but I do think the cognitive visual factors (the sound installation was in a

One thing to bear in mind is that the perception of proximity is far easier to achieve with (fairly rapidly) moving sources. If you get the changing patterns of simulated early reflections right, the ear/brain will focus on the consistent cues (early reflections) and tend to ignore the

The problem is, a sound sources as close to your ear as a mosquito is essentially a mono signal on one ear, you practically hear nothing on the other ear. That's pretty much impossible to do with anything than a headphone setup, or some phase cancelation while your head is clamped down such as
