DIY de-esser (using stereo compressor)?


From my limited knowledge I understand that a de-esser is essentialy a compressor that limits certain frequencies of sibilance.

I also understand that an actual de-esser would be rather expensive due to its special function.

My Question is: Is there any way to use an on-board compressor (say, in the korg d3200) as a de-esser? Something tells me that it might be possible, but I am not quite sure how the whole process works.

Any input would be greatly appreciated.

In order for a compressor to act as a de-esser, you need to access the "detection" circuit of the unit, which is the circuitry that "listens to" the audio program and tells the gain element (i.e., the VCA, opto, etc) how to act. Most analog compressors have this function, where you can patch in an EQ of some sort and BOOST the range you want the compressor to act upon. Some digitally-based compressors have a "library" of options that let you do the same thing in concept. You may consult your owners' manual regarding this (it may be referred to as "sidechain"). I doubt thet the Korg lets you do this, but it is worth looking into.
