MS EQ Comp can encode a standard Stereo (left/right)
signal to MS (middle and side) and add EQ and
Compressor separately to middle and side, and also
edit the volume and pan. The output signal is
decoded to Stereo (left/right).
It helps you to correct the stereo image and the
sound ambience of the music, or add the effects to
the signal of the particular instruments (for
example, drums, vocal, narration, etc) on MS basis.
