Re: Integration of ITD information

[Christian Kaernbach <auditory@xxxxxxxxxxxx>]

Dear Bernhard,

I suppose you look up the work by Jens Blauert, Bochum, Germany, e.g. 
his influential book "Spatial Hearing". I guess the answers to your 
questions are all there. (And if I remember correctly, there is a lot of 
accross-frequency integration, just because of the problem mentioned by 
Jan Schnupp of the missing "line up": that's a perfect cue to detect the 
first wavefront, the only one that is lined up, and the only one that 
gives information on the stereo location not tampered with by echos... 
but then it is not my field of research so my memory might not serve me 
right...)

Best regards,
Christian
