Hi,
Have you looked at any of Angelo Farina's recent work, which
essentially involves beamforming from an Eigenmike but without going
through the intervening step of spherical harmonics, which has some
advantages if you are looking at separating sound sources. A lot of
Angelo's work in the last
Hi,
I work for VisiSonics; we design and build spherical microphone arrays. We
are relatively new company, spun out of the University of Maryland. I
thought one of our early papers could help. It has a lot of good
information on beamforming.
Thanks a lot. I apology for not telling the status of the first order. It
is normal. It has spatial filter effect
but not very obvious. Also, The value of spherical harmonics by my script
is the same as the one computed by the
function of

Hi, all
I think there are somebody have worked about beamforming of spherical array.
Now I want to design the beampattern steering to certain direction and get
the signal from that direction (Sptial filtering).
I get the 32 channels

I get the 32 channels signal p from Eigenmic. Get the Pnm of different
orders

What precisely are you doing with the mic? There are 32 capsules in the
array, so it
