Let's be honest here, upsampling a 44.1/48kHz track all the way to 192kHz doesn't improve the actual sound quality. Just unnecessary resampling, and in some cases, it decreases the quality (except for some very good resamplers, such as SoX). But still resources are spent on unnecessary resampling. But the reason we set Poweramp output sampling rate to higher than 48kHz so that Hi-res tracks with greater sample rate doesn't get downsampled to 48kHz. So it would be nice if there was an option to keep the same output sample rate frequency as the source file. And for files with sample rate less than 48kHz (i.e. 44.kHz CD quality files), it can upsample to 48kHz as Android's default sample rate is 48kHz. For example, there is a file with 96kHz sample rate, I am asking Poweramp to output it at 96kHz. And for a file with 44.1kHz it would resample to 48kHz as Android likes it that way. I mean minimum frequency could be 48kHz. Obviously I am asking to implement this for Hi-res output and AAudio output (if possible).

I've been using the resampler for a while now to upscale 44.1khz songs to 48khz. But, I discovered that of late the resampler function isn't working, even when I restored the default settings. Please anyone with knowledge of the matter help me out. I've attached screenshots of my audio info.

I have Poweramp on a Samsung Galaxy S9 phone, and I use it to send digital signal out to various external DACs via usb otg cable. I just discovered the Audio Info screen for the first time (after using Poweramp for literally years), and was surprised to see that my 16 / 44.1 files are being upsampled to 48kHz. I found the Resampler in audio settings but it only gives the choice between SW snd SoX resamplers -- no option to disable. Is there no way to disable resampling?
