wressa Posted March 14, 2022 Share Posted March 14, 2022 What output do I have to use so that Android system does not resample to 48kHz? Does this occur with OpenSL? What about Hi-Res. Thanks. Link to comment Share on other sites More sharing options...
wressa Posted March 14, 2022 Author Share Posted March 14, 2022 Also is there any difference with Hi-Res other than supporting higher bitrates and sampling rates Link to comment Share on other sites More sharing options...
andrewilley Posted March 14, 2022 Share Posted March 14, 2022 Some devices are set by the manufacturers to force 48kHz output for their normal output, even for CD-quality audio (which is recorded at 44.1 kHz) . If so, you might like to try hi-res and change the output to 44.1, that might get around the issue for you. Andre Link to comment Share on other sites More sharing options...

andrewilley Posted March 14, 2022 Share Posted March 14, 2022 @wressa Looks like a clean 44.1 audio path to me, at least as far as the output to your earbuds. Andre Link to comment Share on other sites More sharing options...

maxmp Posted March 15, 2022 Share Posted March 15, 2022 @wressa looks good, no resampling. Link to comment Share on other sites More sharing options...
andrewilley Posted March 15, 2022 Share Posted March 15, 2022 @wressa Out of interest, what made you think resampling was occurring in the first place? Andre Link to comment Share on other sites More sharing options...
wressa Posted March 15, 2022 Author Share Posted March 15, 2022 @andrewilley Someone I know told me all androids resample to 48kHz for processing and I read about that before online. Didn't see it in the Poweramp audio info though so I wanted to know if it was happening or not. Not that I could hear a difference or anything, just looking to prevent unnecessary battery consumption. Link to comment Share on other sites More sharing options...
andrewilley Posted March 15, 2022 Share Posted March 15, 2022 As I said above, some Android devices do default to 48kHz output in their firmware, but by no means all. And activating hi-res (but at 44.1 output) can usually overcome that anyway. You'd see it in the audio path display if yours was doing that - but there would be next to no extra battery consumption even if it was happening though.

I just got a Shanling M3X DAP and like you noted, the only way I can force Poweramp to output at 44.1kHz is to force it through Hi-Res. Otherwise, if I select "OpenSL ES" as my output, it defaults to 48kHz, and is not allowing me to change it to any other frequency. And if I enable DVC, it changes to 384kHz.

The resampling occurs on certain Android devices especially LG wherein, when connected via a DAC and a Wired earphone, would down-sample it to 48KHZ. You seem to be using Wireless for which this whole issue doesn't apply. Plus Android phones have come a long way and a lot of manufactures have changed the UI and the Software over the course of years. All these issues shouldn't be there at all and there is no concrete proof for this as people who claim this issue have to test it in 100s of Android devices from different makers to validate this claim Link to comment Share on other sites More sharing options...

Most Android devices default to 48kHz, it's rare for them to offer 44.1 other than as a setting in a specificly adjustable mode such as High-Res.

maxmp Posted August 16 Share Posted August 16 In this case (as we don't see the Output section on the screenshot), it's Poweramp who resamples to 48khz as output works or configured on 48khz. If we won't resample, Android will. 48khz is often used for Speaker, Wired headset, and for some BT codecs (LDAC), but 44.1khz is also used for BT SBC, AptX codecs.
