These aren't necessarily where one might hear the differences, of course, [in fact, it theoretically might not be from the ultrasonic content at all
] and I only selected a few that caught my eye, that I thought looked promising because they were somewhat isolated from any strong, adjacent, lower band content (which we know perceptually masks any adjacent, higher frequency content).
I initially had some reservations about marking the peaks, but decided overall it might benefit some listeners, especially the ones who never had a high grade RTA display staring them in the face, in their audio rack, like I did for many of my formative years. I decided overall the pros outweighed the cons, but now I will discuss a possible con.
We must also consider that my video tool (which I've carefully designed so as to not reveal the code letters of which
version of the song "Mosaic" is the hi-res version) might also be used for abuse, or mischief, I'm afraid; an unscrupulous liar, although they can't cheat by using my video itself
, might, for example, proclaim: "See the beautiful musical triangle struck at the 1m24s mark, everyone?' [That's referring to the song's actual
time code, not Youtube's time code] THAT'S
the ultrasonic content where I hear a difference and I am using it to ace my ABX testing! I can hear a difference there, plain as day. Yes siree. The spectral image proves it." [No, it doesn't.]
Whereas they actually cheated by any of the various established cheat methods such as editing their ABX test logs by hand, or simply falsifying the test procedure by dragging in any two songs of their choice, but relabeling them as
"keys jangling full band 2496 test tones f3", "Mosaic XX", etc., prior to pulling them into their playlist to then ABX. Presto, changeo, BINGO, the test result logs will call the two songs exactly
what they told it they were to be called, not the songs' original names. Now they just bring the actual, unmodified ABX logs intact to the thread to brag, lie, and misdirect the other forum members. [Not to imply anyone here would have any motive, financial or otherwise, to lie or cheat, of course.]
