Detailed Description
template<typename NumericType>
struct juce::dsp::StateVariableFilter::Parameters< NumericType >
Structure used for the state variable filter parameters.

Member Function Documentation
◆ setCutOffFrequency()
template<typename NumericType >
|
inlinenoexcept |
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).
