HD Upsampled…An Audio Oxymoron - Real HD-Audio
https://www.realhd-audio.com/?p=1244
Upsampling is a process by which a lower specification audio file is converted into a higher specification audio file using sophisticated software or hardware. A standard CD resolution 44.1/16-bit selection is run through a Weiss Saracon software upsampler (or other high quality converter) to produce a 96 kHz/24-bit “HD Upsampled” file.

In the majority of cases 2x, 4x let alone 40x upsampling will bring no audible benefits. Only in some specific cases it might. 4x or 40x fill not change or increase anything but the price. You would also need to understand that upsampling requires steep digital filtering which also ring around 20-22kHz even when upsampling say 40x.

Closer to home, more digital audio information than we started with. When we upsample a 44.1kHz 16-bit file to a higher rate and depth, like 96kHz 24 bits, we typically get better sound quality. And since the magic of upsampling just sort of works at the touch of a button, we seem to be getting more for nothing.

Lossless on the fly when exporting the files to an iPOD, it an iPOD will accept such a thing... There's no such thing as "lossless" in upsampling, even though you don't have to remove any content, it is (and I mean this literally and mathematically) impossible not to add some minor rolloff or ripple in the frequency domain.
Does upsampling effect audio? | Steve Hoffman Music …

I changed the sample rate on my mac's Audio midi set up to 96 to play hirez files I recently bought. I noticed that the sound when playing ALAC files (16/44) changed significantly. Lower bass, lower volume. Seems this is not an upsampling problem but changing the sample rate certainly changes SQ on CD quality files. I'm using a Dragonfly v1.2 DAC.

They both have adjustments to the upsampling filters and modulators and can use streams from Tidal and Qobuz as well as your files. HQPlayer in particular is very robust in this regard. In essence, one is using the greater computational power of a computer to run more accurate/intensive upsampling whilst reducing the on chip noise created by ...
UPSAMPLED FLAC files...?? - Audio - Linus Tech Tips
https://linustechtips.com/topic/1065246-upsampled-flac-files/
If it's upsampled from an MP3, for example, there will be an artificial frequency cutoff. Take this as an example: This is a rip from a pretty poorly dubbed cassette tape, and as you can see almost all activity stops after 10KHz. But Lossless Audio Checker still considers it a "clean" FLAC, since the cutoff isn't artificially done:

Upsampling is on the other hand a rate conversion from one rate to another arbitrary rate. Oversampling in the ADC has been around for quite a bit of time, while upsampling of audio that results in a simple rate conversion is relatively newer. Upsampling vs. Oversampling for Digital Audio

Some audio professionals call this “over sampling” although I prefer to call it up-sampling. For example, if the original audio is 16 bit/44.1Khz. If you like to convert it from 16 bit/44.1Khz to a higher resolution such as 32-bit float/96Khz; the process is called “up-sampling”. Upsampling is important in audio editing process particularly in audio mixing and mastering.

First, you need to import 'librosa' library Use 'librosa.load' to resample the audio file librosa.load(path,sr) initiallly sr(sampling rate) = 22050.If you want to preserve native sampling rate make sr=None. otherwise the audio will be resampled to the sampling rate provided
