Sound above this cutoff frequency in Hz is not eliminated but increasingly attenuated as the frequency rises further above the cutoff.
The cutoff frequency (sometimes also called corner frequency) defines the point at which the audio is reduced by 3 dB. Thus there will also be a small and decreasing amount of attenuation just below the cutoff frequency as in the following image.
Roll-off (dB per octave)
Roll-off sets the steepness of the attenuation above the corner frequency. Higher roll-off values give a steeper slope to the attenuation. For example, with a roll-off of 6 dB per octave, the sound decreases by 6 dB in amplitude for each octave above the cutoff frequency (an octave above is double the frequency).
|To achieve more attenuation, run the effect again or use a greater roll-off.|
