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. http://plessas.mur.at/rnd/da/Thesis_Plessas.pdf 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 * Charles Henry <[email protected]> [2012-08-21 05:40]: > I have not worked on it, but I think it's really interesting. > Studying microphone arrays for source localization is on my list... > once I get through everything else I started and didn't finish yet. > > I was really wondering about microphone arrays arranged in a circle, > semi-circle, or around the perimeter of a room to pick up sounds > selectively by location.
