Just to state : your point/proposition concerns the (to-be-defined) sameness of
"things" -- by extension also concerning the ambiguity of meaning in general-- due to
the brain's structures/processes, with the problems being, per definition, the
transitions (transitional zones), both in a gradually becoming (prepared) and sudden
manner, yet also "illusionary sameness" (auditory illusions -- sure, the clearness of
meaning is an illusion, too; one could ask whether there do exist any unequivocal
archetypes at all).

-- But you don't want to imply the diversity in personal concept/construct in the
determination, too, will you ; this would be very liberal an approach, though... On
the other hand, including socio/idiolectal differences might really be usefully
included in any determination (as derives from the journals).

-- btw one does also perceive (more "aromatic") differences between 48kHz and 96kHz
sampled clicks ; sure as to the distinctiveness of pitch, the temporal aspect
(expectation) does bring much more into play (any visual parallels ?)

-- You are finding emanations from this field, in general, being too
non-differentiated in composition, then ? -- Source sounds/sound sources that are as
differentiated as the acoustic ones, yet not the same (sound doubles, symbol
sounds...) ?

D'accord (en passant, the formal aspect is always the most easily to tackle one...).

-- Okay, there is also a "transitional zone", again, where a fast temporal sequence
becomes pitch-like ; surely fascinating and difficult to grasp (yet logical by virtue
of a wave's given facts). -- A non-ea/cm, yet not less fascinating example which
comes to my mind now : the harpsichord (in general, as there are different kinds, of
course), which due to construction/resulting spectral distribution often creates a
sub-bass/sub-beat of its own and is very likely to all (deliberate) coherence
phenomena (in Couperin as well as in Ligeti).
