Spatial analysis of room impulse responses captured with a 32-capsules microphone array

The Acoustics of Ancient Theatres Conference

Explanation

Whilst Sherical Harmonics are the “spatial” equivalent of the Fourier analysis of a wavefront,

Our “virtual microphone” approach is the equivalent of representing a waveform with a sequence of pulses (PCM, pulse code modulation)

32 virtual microphones

for 3D map


	[SUI DISEGNI]
	For the horizontal polar we synthesize 24 virtual microphones and for the 3D map we created 32 virtual microphones in the direction of the capsules.
