Cutoff Frequency
from C5 to C10

-60
Frequencies below the cutoff frequency are unaffected by this Þlter. At the cutoff frequency, the
signal is attenuated 3 dB. ThereÕs a rolloff of 6 dB per octave above the cutoff frequencyÑthat
is, the signal is attenuated 6 dB with each octave above the cutoff. The resonanceÑthe amount
of cut or boost at the cutoff frequencyÑis Þxed at -3dB. When the cutoff frequency is well
below the the lowest-frequency partials of a sound, lowering the cutoff further will not affect
the timbre of the sound, but will reduce its overall amplitude.
