Subject: Re: 2d and 3d sound localization From: Zoltan Fodroczi <fodroczi(at)ITK.PPKE.HU> Date: Tue, 19 Jul 2005 22:48:16 +0200Dear Hussein, I plane to finish it not in this week but in this year.. I' amfraid that robust source localization is not in that stage that would be easy to find a generally working and easily applicable algorithms... Nevertheless, I would advise you to contact to the following researchers, since I think they developed the most powerful algorithms: Jacob Benesty - benesty(at)inrs-emt.uquebec.ca "Time-Delay Estimation via Linear Interpolation and Cross Correlation" IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING, VOL. 12, NO. 5, SEPTEMBER 2004 and/or Stanley T. Birchfield - stb(at)clemson.edu "A UNIFYING FRAMEWORK FOR ACOUSTIC LOCALIZATION" European Signal Processing Conference (EUSIPCO) Vienna, Austria, September 2004 If you managed to get an algorithm and you need more help, I would be happy to assist, since I'm also interested in them.. regards zoltan At 22:10 2005.07.19.·ôá', you wrote: >Dear Zoltan > >I need a code whose inputs are real input from microphones.
