Can you fake a hi-res track? 2015-04-09 00:25:33 Is the HF content of >RB sampled tracks sufficiently correlated to the musical content that it would be possible to tell if HF content from a different track were superimposed on an up sampled RB track?Obviously you can't hear it. So I've seen people complaining about early high-res releases that had no HF content, but I believe this was discovered by other means than listening.I could do some experiments myself, but I guess there are a lot of people more experienced at looking at tracks in Audacity than I. I guess that if you put more work into it you might get a more convincing result, but how much work? Could you write a program to do the work? Do we need to treat these things with as much suspicion as retouched digital photographs are now? If not now, then tomorrow?
