QuasiUnaFantasia I also find it amazing when people can't hear the uniqueness in Pianoteq's sound
I can. And as I said I don't like it. However, with recordings or demo I tried, I can hear the uniqueness of sampled pianos too (e.g. Garritan, VSL) and NONE sound anywhere close to the recording of the acoustic the claim to represent. So I similarly find amazing when people rave about these other products :-)
QuasiUnaFantasia but as I've mentioned before, there is the Laurel/Yanni conundrum, so the issue is a well-known one
That's the first time I hear about that. This auditory "illusion" is compared to the Necker cube or the Face/Vase illusion. For me the other two are totally different: I can see either the vase or the faces (and with effort even both at the same time!!) or either position of the cube at will if I concentrate modestly on what I want. No matter how strongly I tried, for the normal clip I can only hear Laurel and never Yanny. Only doing frequency shift with VLC (Tools->Effects->Audio->Advanced) I could hear Yanny (which was a "burped" Yanny) if I adjusted 12 semitones lower! If I increased that frequency shift slowly, by never more than 1 semitone at the time, I could hear Yanny as high as 2-3 semitones down from normal, but it was very unstable and easily became Laurel). If I did the other way around, i.e. slowly going down in pitch from normal, I could hear Laurel down to 8 or 9 semitone below normal!! At normal speed I only and exclusively and strongly hear Laurel and it's beyond me how anybody could ever even slightly hear Yanny!!!!! Yet, at low pitch shifts I could hear both, but as I said not at will only if "coming" from the appropriate direction. And the extremely funny (almost discomforting) thing is that the clip sounds really different when I hear Laurel vs when I hear Yanny. I mean, with the vase/face, I realize it's the same picture and it's me watching it differently. With this, if it weren't my computer with my software, I would suspect that a virus is changing the behavior and playing different audio files!!!
