i was checking what the game peripherals offer in that direction and in the wikipedia it says about the Kinect (Windows SDK) that its „Audio processing capabilities (…) include beam formation“ It has a microphone array built in. The PS Eye also has 4 mics which work plug and play with Pd (contrary to the ones in the Kinect) but the Wikipedia article only says that it “features a built-in four-capsule microphone array, with which the PlayStation 3 can employ technologies for multi-directional voice location tracking”

I've worked a bit with this beamforming 8 microphone setup: manyears.sourceforge.net/ http://sourceforge.net/apps/mediawiki/manyears/index.php?title=Main_Page There is support for an octagonal and a cube array. Maybe it could be ported to Pd?

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. I think that could be used to good effect for performance/recording.

What are you up to now?

Hello, did anyone ever worked on beamforming using microphone array for audio source localisation and noise reduction?

thx Cyrille

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
