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.

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.

Is there any further information on this topic?
