Detailed Description

template<typename SampleType>
class 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.

Member Function Documentation

setRate()

template<typename SampleType >

void dsp::Phaser< SampleType >::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.

setDepth()

template<typename SampleType >

void dsp::Phaser< SampleType >::setDepth

(

SampleType

newDepth

)

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

setCentreFrequency()

template<typename SampleType >

void dsp::Phaser< SampleType >::setCentreFrequency

(

SampleType

newCentreHz

)

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

setFeedback()

template<typename SampleType >

void dsp::Phaser< SampleType >::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 dsp::Phaser< SampleType >::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).

prepare()

template<typename SampleType >

void dsp::Phaser< SampleType >::prepare

(

const ProcessSpec &

spec

)

Initialises the processor.

reset()

template<typename SampleType >

void dsp::Phaser< SampleType >::reset

(

)

Resets the internal state variables of the processor.

process()

template<typename SampleType >

template<typename ProcessContext >

void dsp::Phaser< SampleType >::process ( const ProcessContext & context )

noexcept

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