The Coefficients structure is ref-counted, so this is a handy type that can be used as a pointer to one.

Sets the cutoff frequency and resonance of the IIR filter.
Note: The bandwidth of the resonance increases with the value of the parameter. To have a standard 12 dB/octave filter, the value must be set at 1 / sqrt(2).
