With a samplerate of say 48k and two microphones you can measure phase differences down to 1/48ms or 330m/48000 = 0.7cm I don't know what kind of soundsource you are facing, but if it is anything like this: http://www.huutajat.org/HyvaMP3.mp3 ... you are bound to fail ;) mvh // Jens M Andreasen > has anyone been trying to work on something like that? if so, i'd like > to hear about the results ... > > cheers... tim
