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?

For quite some time music has been mastered at 24/96, then 24/192kHz.
Older analogue recordings were mastered at 16/44.1 during the CD generation and later at 24/96. These hires masters were down converted for CD distribution.

When remastering older recordings they are upsampled and become new "hires" masters. They can then be distributed as hires files (streaming, downloads) or converted back down for Redbook.

So all remasters exist as hires masters today.
But there are still many original digital masters that are streaming at 16/44.1. However, they're being replaced with upsampled remasters.

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.

Re-Masters to me usually spell two things.
"louder remastering" which is useless, because we have enough gain already.
"compression" which just make everything loud, and never seem to give quite sections for the brain to relax, just try listening to Adel’s 21 one of the worst to put on a good system. http://dr.loudness-war.info/album/list?artist=Adel&album=21

Just compare an "earlier release" digital albums, to the later "re-masters"
Green is good, uncompressed. Yellow/orange/red is compressed.

I agree with you George.

Absolutely correct. I always like to see that the producer has used the original analogue sources (or master). Jimmy Page went back to the analogue sources for the LZ remasters, but at some point they were digitized.

I don’t work in the biz anymore, but engineers can work in the digital domain at 48 kHz, 88.2 kHz, 96, 176.4, or 192 kHz.
