Novel approach
m = 1…M
microphones
d = 1…D
directions
Applying the filter matrix H to the measured impulse
responses C, the system should behave as a virtual microphone with wanted
directivity
h1(t)
h2(t)
hM(t)
pd(t)
Target function
c1,d(t)
AM,v
δ(t)
A1,v
δ(t)
A2,v
δ(t)
But in practice the result of the filtering will never be
exactly equal to the prescribed functions pd…..
