Detailed Description

template<typename Type>
class juce::dsp::LadderFilter< Type >

Multi-mode filter based on the Moog ladder filter.

Definition at line 42 of file juce_LadderFilter.h.

Constructor & Destructor Documentation

LadderFilter()

template<typename Type >

juce::dsp::LadderFilter< Type >::LadderFilter

Creates an uninitialised filter.

Call prepare() before first use.

Definition at line 34 of file juce_LadderFilter.cpp.

Member Function Documentation

setEnabled()

template<typename Type >

void juce::dsp::LadderFilter< Type >::setEnabled ( bool  newValue )

inlinenoexcept

Enables or disables the filter.

If disabled it will simply pass through the input signal.

Definition at line 58 of file juce_LadderFilter.h.

setCutoffFrequencyHz()

template<typename Type >

void juce::dsp::LadderFilter< Type >::setCutoffFrequencyHz ( Type  newValue )

noexcept

Sets the cutoff frequency of the filter.

Parameters

newValue

cutoff frequency in Hz

Definition at line 87 of file juce_LadderFilter.cpp.

setResonance()

template<typename Type >

void juce::dsp::LadderFilter< Type >::setResonance ( Type  newValue )

noexcept

Sets the resonance of the filter.

Parameters

newValue

a value between 0 and 1; higher values increase the resonance and can result in self oscillation!

Definition at line 96 of file juce_LadderFilter.cpp.

setDrive()

template<typename Type >

void juce::dsp::LadderFilter< Type >::setDrive ( Type  newValue )

noexcept

Sets the amount of saturation in the filter.

Parameters

newValue

saturation amount; it can be any number greater than or equal to one. Higher values result in more distortion.
