Major Tom Posted December 17, 2018 Share Posted December 17, 2018 After upgrading to Poweramp v3 I have tried 3 different Bluetooth reveivers with all 3 audio engines: OpenSL ES, OpenSL ES Hi-Res and AudioTrack. All of the BT receivers report they can only process 16 bit and 44 kHz. Does it make sense to use OpenSL ES Hi-Res with a higher resolution if the target device can only handle 16 bit 44 kHz? I thought I would hear a slightly improved quality with Hi-Res but this could be a placebo effect. Should I stay with OpenSL ES (without Hi-Res) to ensure a continuous 16 bit 44 kHz signal processing? Or is there any added value if I choose higher resolution signal processing despite the lower resolution of the target device? Link to comment Share on other sites More sharing options...
░▒▓█ クリス █▓▒░ Posted February 26, 2020 Share Posted February 26, 2020 sorry for bumping an old topic, but I was also wondering this. I'm using the new Galaxy Buds+ (with Note 10+) which can only handle 16bit 44khz and I can't decide if OpenSL oder Hi-Res output would be "better" in terms of sound quality. When using hi-res out put I get an Samsung UHQA PCM output of 24bit 48khz. Could someone advise? Link to comment Share on other sites More sharing options...
andrewilley Posted February 26, 2020 Share Posted February 26, 2020 Probably wouldn't help much, some Android devices don't even support 44kHz anyway and force 48kHz. Andre Link to comment Share on other sites More sharing options...
