| Hi there, I am interested in reproducing the approach described in this paper [1] in Csound. What I wonder is if there is a way to “invert” the frequency response of the HRTF filters (in the HRTF.dat files as used e.g. by the hrtfstat opcode)? As a first step I am unsure how to “parse” the data out of these files. Best, Marlon [1] J. J. Lopez, M. Cobos, and B.

Hi Marlon: You can find in this link lots of data about the format of the hrtf data of the Kemar artificial head. I´m sure you can find out there how many hrtf the file holds, the lenght of each hrtf and to the corresponding spatial location of each one.
As for more details on diverse recording techniques, post processing and formats of a lot of hrtf sets, you may consult: You can read it on-line ;) Hope it helps. Best Pablo El sáb., 14 dic. 2019 a las 22:11, Marlon Schumacher (<marlon.schumacher@music.mcgill.ca>) escribió:
