24/96 releases sometimes just upscaled 16/44?

I know many people have developed a special attachment to the CD format - its 16-bits, 44.1kHz sample rate, and its simple interpolation of missing samples to "hide" its read errors represent an almost God-like perfection. This not only brings a great deal of comfort and reassurance to its devotees, but gives the format a unique property or 'essence' which means it can never be bettered.

As one of the deluded and unenlightened heathens who finds himself unsatisfied with CD, I can only beg my superiors to show mercy in shielding me from biased moderation, and from attacks upon my audio equipment, my hearing, my sanity and my brain's ability to adequately perceive not only sound, but the rest of the universe around me.


With that in mind, I have the following quick question:
For test purposes I have acquired a small number of 24-bit 96kHz lossless audio files derived from DVD-A and SACD releases. However, a spectrum analysis of their content always shows a sharp roll-off at either 22050Hz or 24000Hz, suggesting that these releases are nothing more than upscaled versions of previous 16-bit 44.1 or 48kHz releases (complete with the so-called 'loudness war' compression in most cases).

So, is it normal for these high resolution releases to be upscaled?
Which DVD-Audio/SACD releases are known to be genuine 24/96?

Thanks,
jamie.

Let's say it's not that unusual. But the fact that you have 'always' seen it, every time you look, seems unusual to me. How big is your sample?

I don't know know that there is a list today of such things. ISTR seeing a website in the heyday of DVDA/SACD that did tabulate 'real' format information for dozens of releases.

I've analysed 2channel rips of some DVD-As in my own collection, and there were certainly some with > 22kHz spectral content, and also >24kHz IIRC. With SACDs it's a bit harder to tell because instead of ripping I have to capture those from analog output and redigitize at a high SR/bit depth to detect trans-Redbook content.

I find this obsession for ultrasonic frequencies absurd!

Let's rest on a pure analogic field: what content do you expect to find in music at frequencies higher than what players themselves hear and so are able to intentionally produce, and composers to write in the first place?
Only, if something, higher harmonics of the highest tones they could play, quite low in energy compared with audible content and maybe completely masked before they reach a transducer.

Given the ouverture of the OP's first post, I put it in a philosophical way: I think that brickwalling music at 20kH makes it more faithful to what the composer had in his mind when he wrote it! biggrin.gif
