What does the Multiband Compressor do

A multiband compressor (MBC) consists of multiple compressors working in parallel, each operating on a separate band of frequencies. Fractal Audio's Multiband Compressor blocks contains 3 compressors. These compressors work independently, so "pumping" in one band does not affect the others. An MBC is often used as a mastering tool.

Configuring the Multiband Compressor

In-depth programming of the Multiband Compressor is possible, but even at default settings it's performing fine.
