Re: 2d and 3d sound localization

[Zoltan Fodroczi <fodroczi@xxxxxxxxxxx>]

Dear 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@xxxxxxxxxxxxxxxxxxx "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@xxxxxxxxxxx "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
