Low-Pass Filter

From Musician's Business Dictionary
Jump to: navigation, search

A low pass filter is a process of equalization in which the frequencies above the chosen frequency are blocked, leaving the frequencies below to "pass" through. The severity (steepness) of the cutoff at the given frequency can be altered, allowing a smooth yet effective sounding filter. There are many uses for this type of filter, such as creating a "telephone" effect on a vocal track to simulate someone speaking on the other line of a telephone. An identical but opposite use of this type of filter is called a high pass filter. Often times these filters are placed on each end of the portion of the frequency spectrum being used in a particular recording to eliminate any excess noise above or below the desired frequencies.
