> the sound that was recorded and post processed at the time and released is the correct one that's a fun angle - what is the "correct" sound? a different way to define the "correct" sound could be to claim that experience of listening to the band playing live is the one true correct "sound". In principle you could try to approximately recreate that live sound using a live beatles cover band or some kind of computer simulated beatles [+]. but that perspective of "correct" being a live listening experience ignores the contribution of production to the end product that was shipped & listened to, as you're advocating for. [+] e.g. try to simulate the sound of all the instruments and the vocals from first principles or something, perhaps fitting them to the actual recordings using some belief about the observation model & error model of how the true sounds would have gotten recorded/distorted/mangled/mixed into the recorded sounds, using the standard equipment and techniques of the day. now we've turned the problem into an arbitrarily hard ill-defined inverse problem, so we can probably make it sound like however we want depending on what assumptions we make, so arguably this is a weird and overly complex way of producing one of many possible remixes or reinterpretations.
