Not the original commenter, but my guess is, because the cutoff is 22khz, higher frequencies are normalized down around 20-22khz, blending them with those higher frequencies and distorting and changing them slightly. Whereas being mastered for 27khz would allow some of those higher frequencies to remain as is and sound closer to the natural sound you'd hear. I may be wrong but as far as I know, this is because those higher frequencies are still picked up and interpreted by us whether we actually hear them or not. Personally, i've never really noticed the difference between 44.1kHz and 48kHz, but I do notice the difference between listening to audio on headphones with different cutoffs. 20-20000hz headphones sound noticably less good than 18-22000hz or even 24000hz. It makes even more of a difference than price point usually does. To the point where it's the only thing i really look for when looking for headphones for music.

> … because the cutoff is 22khz… That’s the Nyquist frequency. The cutoff is wherever you like, but typically at 20kHz. > …higher frequencies are normalized down around 20-22khz, blending them with those higher frequencies and distorting and changing them slightly. Can you explain what you mean by “normalized down”? It sounds like you are describing some kind of processing done to music, something I have never heard of before, something different from aliasing. I want to assume that you’re commenting in good faith, but are you just rewording the original comment? I don’t think the original comment makes sense, and rewording it isn’t going to change anything. > I may be wrong but as far as I know, this is because those higher frequencies are still picked up and interpreted by us whether we actually hear them or not. This is wrong, or at least wishful thinking—under ordinary listening conditions with typical program material, you simply can’t tell the difference between music which has those frequencies and music which doesn’t. That what experiments are testing when they test if you can “hear” something. > Personally, i've never really noticed the difference between 44.1kHz and 48kHz, but I do notice the difference between listening to audio on headphones with different cutoffs. Different headphones sound different, this is a known fact. There are simply too many differences between different headphones to draw conclusions here. When I’m making music, I try to listen to it on several headphones before I release it. Each set of headphones I have imparts a unique sound on the music. Same thing applies to loudspeakers.
