How can I use another HRTF database (other than CIPIC) in the SphericalPanner?

As far as I know the CIPIC collection are using interaural-polar azimuth as opposed to vertical polar az.

So if I want to change to another collection of HRTFs for example to IRCAMs LISTEN or others that uses vertical polar azimuth. Does that mean that I have to convert them manually in order to have them interaural-polar azimuth?

Hi Anders,

As you point out, in the SphericalPanner, elevation is based on an XYZ cube translated to lateral polar coordinates (like an Earth globe with a pole at each ear). Imagine a room where listener is at 0,0,0 and facing the screen. Y is vertical dimension, X horizontal, Z grows larger into the screen and smaller as it comes out of the screen.

If the HRTF recordings you want to use assume a vertical (rather than lateral) polar elevation then yes you would have to rotate the coordinates (perhaps simply by renaming the files? Not sure how they are formatted).
