The following picture shows a signal with a strong interference in the passband 
(the large peak right of center). 

 

In the resulting audio, typically there would be a strong buzzing sound. After 
engaging the notch filter and adjusting its center and bandwidth (by dragging 
the blue area center and edges) to fall exactly over the interference, the 
situation will look like this: 

 

 

This results in significantly reduced interference and a much more pleasing 
sound.
