There is typically a elevate-and-drop preset option, or a manual slide control that allows the selection of a targeted range; In this case, 60Hz. Manual controls also allow the manipulation of resonance effectually the selected range that permit the user limit the frequencies that the filter affects. This lets the editor achieve a narrower, but cleaner frequency range and tin can finer reduce unwanted audio buzz.
