Atenuación (dB por octava)
Sets the steepness of the attenuation. Higher rolloff values give a steeper attenuation of frequencies below the cutoff frequency. For example, with a rolloff of 6 dB per octave, the sound decreases by 6 dB in amplitud for each octava below the cutoff frequency (an octave above is double the frequency).
Frecuencia de corte (Hz)
Sound below this cutoff frequency in Hz is not eliminated but increasingly attenuated as the frequency falls further below 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 above the cutoff frequency as in the following image.
Para lograr una atenuación mayor, ejecute el efecto nuevamente o use una atenuación mayor.
