Sets the cutoff frequency of the filter. If this is less than the NyQuist limit, then the filter will be disabled.
"Runs" the filter over block.

"Runs" the filter over block.
Processes a single sample with the filter, returning a new sample.
Sets the resonance of the filter. This will be clamped to
RESONANCE_MIN..RESONANCE_MAX.
Sets both the cutoff frequency and resonance of the filter. If the cutoff
is less than the NyQuist limit, then the filter will be disabled. The
