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

Dear Zoltan
I need a code whose inputs are real input from microphones. Thank you for
thinking of sending the code to me (I hope this code finishes this week)
and I hope that I could return the favor.
Regards,
Hussein Slim

Dear Hussein,
If you plane to use input that was created by simulations the problem is
perfectly solvable by the traditional cross correlation function, that is
available in Matlab or even in C from several sources....
In case of real input from microphones the problem is quite difficult the
resolution and the computation requirement is highly depends on the
acoustic environment.. I'm working on a robust algorithm if it's ready
i'll send it to you :)

hello all,
I just want to know where I could find some c or matlab codes for 2d or
3d
sound localization (a code that returns for me the azimuth and the
elevation
of the sound source with respect to the robot)
thanks
Hussein
