This is great - it's not often we get classical music here. Very welcome.
One thing I don't understand - when you say 4 hands, I take it that means a duet, not two tracks mixed?
4 hands just means 2 people. They also say how many pianos-1 or 2. This piece is 1 piano- 2 people. I knew I would edit this a zillion times so I haven't even named it properly yet.
I came across this while searching how to edit mis/side recording. It really works.
"Mid-side recordings are sometimes said to lack spaciousness. But according to David Griesinger, this
can be improved with spatial equalization, in which a circuit boosts the bass 4 dB (+2 dB at 600 Hz) in
the L - R, or side, signal, with a corresponding cut in the L + R, or mid, signal. Another way to improve
the spaciousness is to mix in a distant MS microphone -- one set about 30 ft from the main MS
He doesn't say what to set the Q of the equalizer to. I used the default setting on my EQ and that's 2.75 Oct. (octave). I'm still messing around with this but I'm using (in Voxengo HarmonEQ) 600HZ, 2.5 to 3 db cut or boost, 2.75 octave.
In Fl Studio I copied the side mono file and reversed the phase on the second one. Pan Hard left and right. I also copied the mid mono file. Pan both to center.
channel 1-mid mono file (EQ cut) pan to center
channel 2-side mono file (EQ boost) pan hard left
channel 3-side mono file phase reversed (EQ boost) pan hard right
channel 4-mid mono file (EQ cut) pan to center
Here's a link to the file. It's pretty informative. This was on page 6;https://pantherfile.uwm.edu/type/www/42 ... adings.pdf
I haven't posted this tune using this technique yet cause I want to fine tune it but it sounds much better now.
