Dear Steven,
In my opinion, the main problem is the limitation of the playback system to
16/8kHz.
No matter what we process before output, we have to downsample to 16/8kHz
when playback. Therefore, the useful information in high frequencies is
lost, which hampers the localization performance.
Dear Steven and Fons,

improve the sound localization performance, I am now wondering whether
there is a certain good method to solve or mitigate this problem in this
scenario.
Any discussion is welcome.
Thanks a lot again.

Thanks a lot for your reply.
Yeah, the headphone that you mentioned is what I am researching on.
What I am wondering is how to implement this headphone technically. Which

Is there any further information on this topic?
Thank you.

Dear Jorn,
well, if you have headphones, you have to be doing binaural synthesis.
so what happens is you take the positions of the speakers you want to
simulate, and convolve each speaker signal with the appropriate head-related
transfer functions for the left and right ear.

Thanks a lot for so valuable comments and active discussions.
