FXAlg #953: Compress w/SC EQ
Stereo soft-knee compression algorithm with filtering in the side chain
Allocation Units:
2
The Compress w/SC EQ algorithm is the same as the SoftKneeCompress algorithm except that equalization has
been added to the side chain signal path. The equalization to the side chain includes bass and treble shelf filters and
a parametric mid-range filter.
Compressor with side chain equalization.
Using side chain equalization allows you to compress your signal based on the spectral (frequency) content of your
signal. For example, by boosting the treble shelf filter, you can compress the signal only when there are a lot of high
frequencies present. This technique is often called Òde-essingÓ, because it is useful for removing excess sibilance
from vocals.
