Detailed Description

template<class T>
class Aviate::LowFrequencyOscillatorVector< T >

The LFO is commonly used on modulation effects where some parameter (delay, volume, etc.) is modulated via waveform at a frequency below 20 Hz.

Waveforms vary between -1.0f and +1.0f.

Template Parameters

the	data type of the oscillator

this LFO is for operating on vectors of audio block samples.

LowFrequencyOscillatorVector()

template<class T >

Aviate::LowFrequencyOscillatorVector< T >::LowFrequencyOscillatorVector

(

Waveform

waveform

)

Specifies the desired waveform at construction time.

Parameters

waveform

specifies desired waveform

Member Function Documentation

getNextVector()

template<class T >

(

)

Get the next waveform value.

Returns

the next vector of phase values

setRateAudio()

template<class T >

void Aviate::LowFrequencyOscillatorVector< T >::setRateAudio

(

float

frequencyHz

)

Set the LFO rate in Hertz.

Parameters

frequencyHz

the LFO frequency in Hertz

setRateRatio()

template<class T >

void Aviate::LowFrequencyOscillatorVector< T >::setRateRatio

(

float

ratio

)

Set the LFO rate as a fraction.

Parameters

ratio

the radians/sample will be 2*pi*ratio

setRoundnessFactor()

template<class T >
