Multiband Compression
Definition
A compressor that divides the frequency spectrum into multiple bands and applies independent compression to each. Allows precise dynamic control in specific frequency ranges without affecting others.
In Simple Terms
A compressor that works on different frequency ranges independently. It can tame boomy bass without affecting the sparkle of your cymbals. Powerful but easy to overdo-use it when regular compression isn't surgical enough.
In Practice
A multiband compressor in mastering controls excessive low-mid buildup when the bass plays full notes, without reducing the energy of the high frequencies simultaneously.
Common Confusion
A multiband compressor is not "EQ with dynamics." It applies compression only when a band exceeds its threshold; it does not statically boost or cut. Used as a static tone-shaper, it sounds like an inferior EQ. Used to control problematic dynamic resonances (vocal sibilance, bass buildup, harshness peaks), it solves problems that EQ alone cannot.
