I'm sure all of this has been debated endlessly on here before but I have not read it personally. My thinking is that although it is of course possible to use multiple microphones, multi-track recordings and mixer desks to manipulate the music any way you like, it is then dependent on the recording engineers to ensure that instruments are given their correct level in the master recording.
On that subject, who is to say what is the correct level for a particular instrument or section of the orchestra. To me it is intuitively based on their positioning on the stage, e.g. violins on the left, violas to the right etc as heard by everybody in the audience in slightly different ways based on their location in the concert hall. In the early days of electrical recordings microphones were placed in a single location according to only two different methods (amply described here -
https://www.mixonline.com/recording/orchestral-recording-365592) with essentially only 2 or 3 microphones dependent on the method adopted. My personal thinking is that this was as good as it could be since it reflects one (the best hopefully) location in the concerto hall to appreciate the entire orchestra, much as any one person could do if they were sitting there.
The obvious problem with multi-microphone method (I understand that they now adopt the 'Decca Tree' method with additional spot mikes placed in each orchestra section) is that the essence of the orchestra is then adjusted according to whatever the recording/mixing engineer (or sometimes the conductor !) thinks is right for the piece of music being performed. I understand that this is also adjusted during the recording session to emphasise particular instruments in the mix before the final recording is ready for replication, which is potentially even further away from the original production.
I think the previous poster made some very pertinent points there, '
in the old days they had to get it right first time' and '
to get a really good recording still takes a great deal of skill and care'. It's also worth noting that many of the recordings that we can buy these days are essentially re-mastered versions of recordings done 60 or more years ago (good and bad) as noted above. Not all of the re-mastering is 'successful' in my view.
Just my two pennyworth obviously.
