Shelving filter explained: understanding high-shelf and low-shelf
WebA low-shelf filter is a filter that either boosts (increases amplitude) or cuts (decreases amplitude) frequencies below a certain cutoff frequency. These filters generally have a well-defined transition band and a levelling-off of amplitude in the lower end.

WebApr 29, 2015 · Low-pass and high-pass filter alignments can also be defined this way. One difference about all-pass filters is that for each order there is 180° of total phase shift. Low-pass and high-pass filters have only 90° of total phase shift for each order. The importance of this distinction will become clear later. Figure 3: Example dual 12″ woofer, A low-shelf is used to boost or attenuate the frequency spectrum’s low end. You can see this in the following examples. Here, the low end of the frequency spectrum is being boosted: Whereas here, the low end of the frequency spectrum is being attenuated: You will notice that there is a transition band over … See more A high-shelf is used to create a boost or attenuation in the frequency spectrum’s high end. Here, the high end of the frequency spectrum is … See more A shelving filter’s gain setting is used to control the amount of boost or attenuation that is applied. See more Shelving filters have three main controls. They are the filter’s gain setting, its frequency setting, and the steepness of its slope. Let’s look at each control in more detail… See more The frequency setting defines the point at which frequenciesabove (high shelf) or frequencies below (low shelf) are cut or boosted.
