I saw that the last update added DSEE HX for this model(XA2), but on some Sony sites , like this https://blogs.sonymobile.com/2016/03/15/behind-the-acronym-dsee-hx-with-audio-engineer-kenichi-matsu..., it wrotes that DSEE HX was made to upscale MP3 to near HI-RES. But, on this site https://blogs.sonymobile.com/2018/10/01/experience-hi-res-audio-with-the-xperia-xa2-and-xa2-ultra/ it says that you need FLACs or WAV files. So, DSEE HX will upscale Mp3/Mp4/AAC file to 24bit/96khz on XA2 or only FLACs ?
And what is the target "quality" ? 24bit/96khz or less ?
Also does it work only in Music app or it's global(for YT/Spotfy/Video, etc) ?
