The Quest is in some ways the same one for the 'tone' camp (SETs, vinyl, horns, field coils, etc.) and the multi-channel, DSP correction, digital crew. How we get there is where the differences are. And if you say that the sounds the two camps seek are extremely different, then you are going to prove my next point: the ability to tonally adjust the sound at the source. Equalizers and tone controls are just rearranging deck chairs after the boat has been built in the sense they are 'gross' adjustments. But with enough bandwidth to deliver a piece of program material into its constiuent parts, why couldn't the user 'adjust' the sound to the room and to his/her taste in much finer increments by making relative gain/tone/phase and other corrections to multiple tracks of the recording that are delivered to the end user as multitrack? (I'm not just talking about multiple channels, ala surround sound, but separating the horns from the drums from the vocals and giving the user the ability to adjust each of them). Yes, I know, in some ways unnatural, but as one thread here noted, very few recordings are set up for a 'natural acoustic' in the first place. And, without having everyone play recording engineer at home, with a complex board, you could have presets, both from the factory and from knowledgeable tweakers, tied to particular recordings. (Crowd-sourcing of presets?). Keep in mind that I'm not talking about DSP at the room end, although that may be important, but altering the fundamental balance of a recording at the source material playing in your room. Just a crazy thought.
Mixing is my true musical love.
