So much so for the non existent qualities or "ethereal" one i speak about speaking of timbre, it seems they exist :
«In short, timbre lives not in the audio signal or in a musical score but in the mind of the listener.» P.20 of this book....lower in the post...
I will precise in the specific ears/ specific brain/ specific room of the "learning" listeners to be understood here by some....
Then to digitalize something so analoglike than timbre we must first recognize the phenomenon and define it with many descriptors....
The scientific theory of these mathematical descriptors is in progress say this first book about all aspects of the concept of timbre....I guess the digitalization modelization of timbre will progress also compared to the actual state indeed....
But it seems that it is possible that actual dac engineering being able to mimic analog turntable are not necessarily superior on all counts, all times, with any dac, in any room against any audio system....Too much factors.... Anyway it is each times our ears that decide if the timbre reproduction is natural or not, not an engineer on audiogon for us all, once for all, it seems....
Each/brain/ears/room are different, without speaking about the different dac, and different audio systems possible....
In one word: TIMBRE is not an "object" that engineers modelized easily once for all thanks to the Nyquist Theorem , it is first and last a learning complex process in variable acoustic environments for human ears....It is then human ears that decide if the timbre is rightly perceived or not ( it is also an objective/subjective interface problem)....The theorem is only about the relations of coding and sampling analog signals...Timbre is not simple signals sampling it is a bundles of acoustical phenomena in relation to an hearing system....
