There's services who can calculate a personal HRTF based on 3D scans or measured dimensions of your head, like here: https://mysofa.audio/index.html#HOWTO ... can't tell anything about the quality of the results, never tried those. Jeanette C. wrote on 20.01.2020 04:20 (GMT +01:00):

There are some commercial systems (Android apps) claiming to do this, using e.g. pictures of your head and ears. AFAIK, none of them really work, it's all hype and easy money. Indeed. And if these personalised HRTF have to be useful at all, e.g. for binaural with head tracking, you need a lot of them, in all possible directions. I've been working on binaural reproduction for some years, and at the same time some of my collegues have been exploring how to get personal HRTFs, and how these could improve things. None of the methods they tested has produced anything really useful. In some of the listening tests we conducted, people have evaluated their own personal HRTFs (obtained by different methods) as not working at all, while some generic ones (from dummy heads) worked very well. There are other aspects of binaural reproduction that seem to be much more important - can't go into the details, but room sound and correct head movenent tracking are among them. One reason is that your hearing will adapt to an HRTF set after a few tens of minutes of listening, assuming the rendering system is OK and provided the HRTFs uses are 'plausible', i.e. not completely wrong. The adaptation is permanent if the exposure has been long enough - you can come back later and things will still work. This is only to be expected if you think of it for a while. Your perception of reality doesn't break down if e.g. you wear a cap because it's cold or raining, or when you move your earflaps a bit forward or press them against you head. Ciao, -- FA
