Tidal/qobuz hi-res track vs a 44/16 track upsampled in Roon?

That being said, your assumptions that most tracks are just up-converted from CD is wrong. That would simply constitute fraud as far as I’m concerned.

Gotcha. Wasn’t sure. There’s another thread on this (which you also replied to!), which states the streaming services get the hi-res (remastered) files from the studio.

Where does Hi Res audio originate?

This is opaque to me… Qobuz has some recordings at greater than CD quality. HDTracks, same. How do they get these? And is their hi res different than me upsampling? What bitrate and sample frequency do studios record and capture digital audio in? That seems to be the base limit of what we can acquire and what streaming services can deliver. Are Qobuz/HDTracks or anyone else receiving high bitrate/high sample rate files from the studio? Or are they upsampling CD quality data? I’m pretty…
