Thank you for the response, Roger!

	I tried the link you gave me for the HRTFcompact file, but just got a
line of symbols displayed on my browser.  In the previous directory
(Analysis/) the file is shown as having a size of 184k, but I can't get
anywhere with it.  Any ideas on this or on any other sites I could get
the HRTF measurements from?

thanks for the help,
james
