About the Multiband Compressor block

A multiband compressor consists of multiple compressors working in parallel, each operating on a separate band of frequencies. Fractal Audio's Multiband Compressor employs 3 compressors. They work independently, so "pumping" in one band does not affect the others.

Multiband compression can be useful for mastering, for balancing high-gain guitar tones (palm mutes), and acoustic guitars.
