My moneys on wetteke, but I can't prove Outlaws is wrong.
schnoops said:Yes man it's possible to mix with azimuth and elevation, yes man it's psychoacoustics....
Did you know that our ears, lobe, pavillion, cartilage, etc process the sound BEFORE it reaches the little hole?
Everybody has his own HRTF, Head Related Transfer Function, and that's what gives us the full 3D reconstruction of sounds in our brain.
tha's why we can tell when a sound is coming from behing rather than front, from above or below, etc...
The HRTF is a bidirectionnal filtering function, whose frequency plot actually depends on the relative position of both the head and he sound source. that's why it's called head related.
Some dudes carried out maesurments on a standardized puppet, and cam up with packages of generic HRTFs, one for a 30° elevation with 15° azimuth, same with 5° increments... etc
Impulse responses also capture the 3"Dimensionality" of real acoustic spaces... there's a huuuuuuge project on auralization for symphonic ensembles where the composer will be able the reconstruct a virtual take with genuine 3D sound field reconstruction from a huge collection or impulses and technic data on sound diffusion patterns for each instruments...
