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.
