El Filtro de paso bajo permite el paso de frecuencias bajo su frecuencia de corte y atenúa las frecuencias sobre este. Este efecto puede ser por lo tanto usado para educir ruido de tonos altos.

Atenuación (dB por octava)

Sets the steepness of the attenuation. Higher rolloff values give a steeper attenuation of frequencies above the cutoff frequency. For example, with a rolloff of 6 dB per octave, the sound decreases by 6 dB in amplitud for each octave above the cutoff frequency (an octave above is double the frequency).

Frecuencia de corte (Hz)

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.

Para lograr una atenuación mayor, ejecute el efecto nuevamente o use una atenuación mayor.
