Comb Filter hollows out the sound by carving out frequencies at each multiple of the base frequency, like the teeth of a comb.
Compressor helps shape the dynamics of the sound both at the initial attack and the sustain tail with sweetness.
Dynamics is a classic compressor, upward compressor, and expander in a single plugin. This allows you to process the quietest part of your sound and the loudest part individually, resulting in either very transparent control of volume, or full domination of your dynamic range.
Disperser rotates the phases of your signal to create frequency sweeps. It smears high energy transients through space and time without modifying the gain of the sound.
