S&M stands for “Sum and Minus” and is a play of words on the techniques of
Middle-Sides recording. This device, with the addition of appropriate analog processing
gear allows the engineer to enhance the stereo effect of mixes or a pair of tracks in the
mix. One can correct subtle mistakes in a mix quickly without having to set it up and run
it again or re-record tracks (toss out keepers due to minor mistakes). As a mastering
device, the S&M can help an engineer correct even serious problems that would usually
be thought of as ‘unfixable’ quickly and easily (i.e. vocals in the center too bright, guitars
on the sides too dull). A stereo pair of room mikes that have the ‘perfect’ drum sound,
except the snare is too loud, can be fixed easily with a limiter in the Sum channel, etc.
The ground work for these techniques was invented in the 1930’s by Blumlein and
resurrected in the 1990’s by Muth for modern rock and pop music recording and
mastering as used by top engineers in the music industry using his custom equipment.
