What does resonance do on a filter?

In a highpass filter, Resonance emphasizes or suppresses signals above the cutoff frequency. In bandpass/band rejection filters, resonance emphasizes or suppresses the portions of the signal—the frequency band—that surround the defined frequency, set with the Cutoff Frequency parameter.

What produces a filter resonance?

A filter removes frequencies (harmonics) from the incoming audio signal, above the cutoff frequency (low pass) or below the cutoff (high pass). Resonance is an additional controlled amplification of that cutoff frequency, creating a secondary peak forms and colors the original pitch.

What is resonance in sound design?

Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies).
