Back on Friday 16 May 2008, Steve Fosdick was like: This "dynamic EQ" is a bunch of BS. They like to market this stuff as some sort of EQ that automatically adjusts, which is a load of bull. Real "Dynamic EQ" is riding the EQ knobs while somebody is playing / singing. This is nothing more than a compressor with a sidechain. The input for the sidechain is a split off the signal input for the compressor, and is run through a bandpass filter (or whatever type of processing works best for what you're trying to achieve) first so that you can have control over what frequency range is triggering the compressor. There are several LADSPA compressors with sidechain inputs that can be set up with something like Ingen to achieve a "Dynamic EQ". Be aware though that this is not EQ. This is dynamics. -Reuben
