Upsampling doesn’t bring any new info to the recording from 16/44.1 so can they be even considered hi res? Unless they go to the original analogue master and remaster it 24/192.
high resolution streaming
I am not sure if this has been thoroughly discussed before but I have both Tidal and Qobuz. When they have "high resolution" music are majority of them truly remastered at high resolution from master recordings (analogue or high resolution digital) or just upscaled from CD? Any idea what % of the music at Tidal and Qobuz are "truely" high resolution?
