24/96 releases sometimes just upscaled 16/44?

As an example though, at least one commercial quadraphonic LP system (Quadradisc) used a pair of modulated carriers for the extra channels' content, cut to the vinyl in the range of 18-45kHz. High end record players can reproduce even higher frequency signals. Why would you want that?'fails gracefully? "subjectively usable dynamic range'? capturing extra 'information'? Welcome to analogue recording - things aren't so clean-cut as with digital are they. You can use the same terms and methods for both analogue and digital audio, since you can sample your analogue signal into a digital form without loss of information. Then you can compare both in the digital domain. You don't have to make up terms which you only define for analogue recordings, to imply that there is some "hidden" information in the analogue recordings.My original post was about sourcing genuine native 24/96 recordings to try out on my new soundcard - nothing more. From my understanding you wanted to have a reason why there are 24/96 releases with sharp roll-offs, which are apparently sourced off of lower sampled releases:So, is it normal for these high resolution releases to be upscaled? And this dissolved into (albeit interesting) banter about technicalities of high-res audio recording. The real question was never investigated: Why do some recordings look like they are just upsampled? And to me the answer is quite simple: Either there were no master tapes which higher frequency content, or the content was deliberately removed. Or the person in charge was unable to create a high-res master. In any case some consumers will just buy anything with large enough numbers on it, so it is a good business decision to just deliver what the customer wants and cut some corners in the process, if another approach takes too much effort.
