Here’s the thing… if an instrument or voice is recorded, it’s processed. Period.You also MISS the point...
Everything is processed in a way or in another,yes, but some music is TOTALLY processed...
If everything is processed to some degree, ANYWAY we know how must sound a natural voice and a noremal piano ALREADY in our memory....
We have an imprinted distinctive physionomy of the sound in our brain...
Acoustic science is not taste or fad. Period.
Judging an audio system ask for an archetypal model to go with, human voices and natural non electrified instrument timbre are these phenomena acoustician or musician use.... Not Moog synthetiser or electrical guitar....Or too much processed voice....
