Hi Gernot, I haven’t used the toolkit, but I don’t see the reason for HRTF interpolation in a predefined grid - if you generate the spherical harmonic filters for whatever HRTF set you have without interpolation, then all you need in AmbiX is a binaural decoding configuration file with a (N+1)^2 x (N+1)^2 decoding matrix that is a unity matrix (zeros everywhere and ones in the diagonal), along with the (N+1)^2 stereo WAV files of the filters you generated (where N is the order you are going for).

[http://idaaudio.com/professionals/ <http://idaaudio.com/professionals/>] Regarding the import of SOFA files into the ambiX binaural player the Princeton University 3-D Audio & Applied Acoustics Lab has developed the SABRE toolkit specifically for this task (https://www.princeton.edu/3D3A/SABREToolkit.html <https://www.princeton.edu/3D3A/SABREToolkit.html>). Requires MATLAB knowledge and decisions about interpolation "when measured HRTFs are not available at the desired grid positions". Anyone having experiences with this toolkit? -- Gernot On Sun, 5 Nov 2017 09:59:36 +0000 Augustine Leudar <augustineleu...@gmail.com<mailto:augustineleu...@gmail.com> <mailto:augustineleu...@gmail.com>> wrote: Let us know how you get on with height.... I also wonder how much ground and shoulder reflections will count and if subjective visual/cognitive assessments of environment affect localisation in a significant way - interesting to see. If anthropometrics alone are enough.

The resulting 3D model is also not as good as the ones shown in the promotional video, so I will probably try again because I suspect that a better video would help to produce a better 3D model, therefore a better HRTF profile. I'm still in the process of evaluating the SOFA file I received (in my free time, something I should continue tomorrow). So far the results are very interesting; it does work. I will try to compare it with some generic HRTFs, and I will report here. One of my problem is the lack of software to use a SOFA file. My evaluation tool is now JSAmbisonics, because it's free (as in speech). I guess I could also use the ambiX binaural player, but that would be more work. -- Marc On Sun, 5 Nov 2017 00:07:59 +0000 Augustine Leudar <augustineleu...@gmail.com<mailto:augustineleu...@gmail.com> <mailto:augustineleu...@gmail.com> <javascript:;>> wrote: Looks interesting - anthropometric approach.
