Re: [microsound] wave field synthesis

[James McCartney <asynth@xxxxxx>]

This can only work up to some low frequency based on the distance 
between the speakers.
To create an illusion of a point source you'd need a speaker every half 
wavelength wouldn't you?
That'd be every 6.7 inches (17 cm) for 1000 Hz.
