When I have mixed in surround I have often used M/S recordings and my
standard practise would be to mix the original recording into AB stereo bung
this in the rears then spread the M/S signal across the front bringing up the
centre image in level relative to the rears. Having done this I set the rears
3dB quieter overall. This is my default approach and then I tweak from there.
The final mix does then of course then get dolby encoded.
What are the differences between my approach and your processor?
What do you mean by "Some" of the signal?
What is the SurroundPlus matrix?
>we re-combine the two signals as encoded surround
Is this signal encoded as LCRS or 5.1?
Has anyone got any different ways of deriving a surround atmosphere from
M/S?
Tom
