[PD] beamforming, mic array and audio source localization

[Johanna Nowak]

Hi,

there is some research using a 120 channel microphone array here:
http://plessas.mur.at/rnd/rnd.html

Page 55 of this thesis shows a Pd patch using spherical harmonics.

This link to a video demo of 1st order beamforming using a nice GEM
gui is also available: http://plessas.mur.at/rnd/demo/demo.html

It seems that IEM does a lot of work on the topic, and I am sure they
use Pd there! :-) see for example http://iaem.at/Members/zotter

best, Jo
