I think the Microsoft Kinect comes with a Microphone Array.

PS3 Eye too, 4 microphones AFAIK. Those had a big discount on Amazon recently.

EDIT: Still are, 5 bucks.

I've got one knocking about in the drawer. Let me know if you get beamforming working on it. I think there are multi channel audio drivers for Linux/RPi for PS3 Eye

Welp, looks like I just bought 3, haha! Thanks!

Yes Kinect has an array of 4 mics and can do audio beam forming. Plus there's a terrific SDK for Windows.

I said it in a thread about the Kinect - I think it's only 135 (ish) degrees of reception, and sometimes it can be more finicky than that.

I'd love to get my hands on an open source array.
