OPTIMIZER

of the audio spectrum to contrive a bandpass filter for the

production of ‘telephone’ effects and similar treatments.

In the High-pass and Low-pass modes, the Q control

changes the filter characteristic from over damped to under

damped, with the higher Q settings producing a tighter,

more focused sound.
