The claim of the ignorant. We have 0 issue measuring differences. What we can’t do is interpret how some may perceive that. However, we are pretty good at determining if it will be perceptible.How do you measure natural timbre perception in a room refining the room settings WITHOUT human ears?
For depth imaging it is the same thing ? HOW ?
I forget that you dont even know they are MAINLY and FIRST and LAST neuro-physiological phenomena coming from the room AND the speakers tuning, not from electronic settings which is necessary but secondary....
Then they are NO WAY to measure timbre perception and depth imaging WITHOUT human ears...
An electronic tool is only that a tool, not a MEASURE of the perceived timbre or depth imaging....The real measure is provided by the listening ears....For sure it is theoretically possible if we use an A.I. to mimic that, but we speak here bout the normal tools at hands and the usual condition in audio experience...
Anyway, anyone knowing what are these phenomema and when emerge these phenomena in a room for some ears know that it not possible to recreate them out of electronic method ONLY....
Save for a perfect audio laboratory where all variables could be controlled no ears are needed there for sure except at the end to assess the job done... Then your affirmation that all could be measured witout EARS is false in the usual settings of the average listener... EARS are mandatory here to controls the parameters of ALL tools at hands...
Saying half truth is distorting reality....
