Unlike a parametric filter, a shelving filter is designed to boost or cut the signal at the target frequency and continue that boost or cut into lower or higher frequencies past the target. A shelving filter gets its name from the distinct shelf shape it forms in the EQ's frequency graph. Shelving filters come in two distinct flavors: high shelf and low shelf. With high-shelf filters, the frequencies above the target frequency are boosted or cut uniformly through the top end of the EQ. With low-shelf filters, the frequencies below the target frequency are boosted or cut uniformly through the low end of the EQ. Let's hear some shelving filters in action.
