M/S Leveling
As with Upward Leveling, long attack times are the secret of M/S Leveling. Here the compressor re-
acts primarily to the complete signal energy and less to single rhythmic accents. If this principle is
now used on the side and the middle channel separately, a stereo mix will become more compact
in an unobtrusive way and everything will sound a little more vivid. This method is especially inter-
esting to enhance rock and pop tracks in a discreet but effective way. Here the feed forward mode
is active again. The ratio is set at about 1:1.5 and the gain controller at about 3 dB. The threshold is
adapted to a value that results in approx. 3-4 dB.
Groove Compression
Sometimes it would be great to be able to just emphasize the rhythmical elements of a mix in
order to bring out the groove with the aim of giving the track the right kick. The figure shows how
the alpha compressor can help you to cope with this challenge. The bass drum is used as a trigger
for the compressor; therefore the sidechain filter is of special importance in this application. It is
set to low pass, with a center frequency of approx. 70 Hz. Now the threshold and ratio controllers
are used to set the intensity of the gain reduction, and the groove will be controlled by the release
parameter, which has merely to be adapted to the speed of the track. Depending on the song and
the style of music, the gain reduction can be higher by all means; usually 5-6 dB will do very good.
The linked M/S mode makes sense in this application, because the influence of the bass drum on
the control process is enhanced as well as the resulting sonic effect.
