Notch Filter

The Notch filter is used to attenuate the selected frequency and its harmonics. Like all parametric filters, this one is usually used to correct various imperfections in the original audio.

Use the Play buttons to listen to and compare the sound before and after applying the Notch filter:

Notch Filter Settings

To apply the effect, use one of the available presets or configure the effect parameters manually.

The following Notch filter settings are available for editing:

• Frequency - sets the notch frequency (the one you want to attenuate).
• Bandwidth - specifies the band of frequencies around the notch frequency that will be affected by the filter in percent. The bigger the value, the wider the band.
• Suppress Harmonics - tick this option to suppress the notch frequency harmonics. The program will eliminate a maximum of 4 harmonics. Suppressing harmonics will help eliminate unwanted hum.
