Detailed Description

template<typename SampleType>
class juce::dsp::Phaser< SampleType >

A 6 stage phaser that modulates first order all-pass filters to create sweeping notches in the magnitude frequency response.

This audio effect can be controlled with standard phaser parameters: the speed and depth of the LFO controlling the frequency response, a mix control, a feedback control, and the centre frequency of the modulation.

Constructor & Destructor Documentation

◆ Phaser()

template<typename SampleType>
Phaser::Phaser ( )

Constructor.

Member Function Documentation

◆ prepare()

template<typename SampleType>
void Phaser::prepare ( const ProcessSpec & spec)

Initialises the processor.

◆ process()

template<typename SampleType>
template<typename ProcessContext>
void juce::dsp::Phaser< SampleType >::process ( const ProcessContext & context)
inlinenoexcept

Processes the input and output samples supplied in the processing context.

◆ reset()

template<typename SampleType>
void Phaser::reset ( )

Resets the internal state variables of the processor.

◆ setCentreFrequency()

template<typename SampleType>
void Phaser::setCentreFrequency ( SampleType newCentreHz)

Sets the centre frequency (in Hz) of the phaser all-pass filters modulation.

◆ setDepth()

template<typename SampleType>
void Phaser::setDepth ( SampleType newDepth)

Sets the volume (between 0 and 1) of the LFO modulating the phaser all-pass filters.

◆ setFeedback()

template<typename SampleType>
void Phaser::setFeedback ( SampleType newFeedback)

Sets the feedback volume (between -1 and 1) of the phaser. Negative can be used to get specific phaser sounds.

◆ setMix()

template<typename SampleType>
void Phaser::setMix ( SampleType newMix)

Sets the amount of dry and wet signal in the output of the phaser (between 0 for full dry and 1 for full wet).

◆ setRate()

template<typename SampleType>
void Phaser::setRate ( SampleType newRateHz)

Sets the rate (in Hz) of the LFO modulating the phaser all-pass filters. This rate must be lower than 100 Hz.

◆ update()

template<typename SampleType>
void Phaser::update ( )
private
