Shelving Filter Basics

An equalizer is effectively a kind of processing buffet, offering a selection of different filter types for users to dish out as they like. Each of these filters can change the frequency balance of a sound in a different way, so the first decision you have to make with any equalizer is which filter types to use. The best one to start off with when balancing a mix is called a “shelf” or “shelving” filter, a broad-brush processor that can change the level of one whole end of the frequency spectrum. The filter comes in two variants: a low shelf, which affects the lower end of the spectrum, and a high shelf, which affects the higher end. Shelves have at least one user-variable parameter, gain, which simply deter- mines the level change applied to the filtered frequency region. The other main attribute of the filter is its “corner frequency,” the notional boundary between the processed and unprocessed frequency ranges. Some EQ designs have shelving filters with fixed corner frequencies, but this usually restricts your options too much for critical balancing work, so seek out an equalizer that has a freely variable Frequency control instead.
