A set of coefficients for use in an Filter object.

using juce::dsp::IIR::Coefficients< NumericType >::Ptr = ReferenceCountedObjectPtr<Coefficients> |
The Coefficients structure is ref-counted, so this is a handy type that can be used as a pointer to one.

juce::dsp::IIR::Coefficients< NumericType >::Coefficients | ( | ) |
Creates a null set of coefficients (which will produce silence).

Directly constructs an object from the raw coefficients. Most people will want to use the static methods instead of this, but the constructor is public to allow tinkerers to create their own custom filters!
