## Detailed Description

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

Generates a signal based on a user-supplied function.

Definition at line 35 of file juce_Oscillator.h.

## Member Typedef Documentation

## ◆ NumericType

template<typename SampleType >

using juce::dsp::Oscillator< SampleType >::NumericType = typename SampleTypeHelpers::ElementType<SampleType>::Type

The NumericType is the underlying primitive type used by the SampleType (which could be either a primitive or vector)

Definition at line 41 of file juce_Oscillator.h.

## Constructor & Destructor Documentation

## ◆ Oscillator() [1/2]

template<typename SampleType >

juce::dsp::Oscillator< SampleType >::Oscillator | ( |  | ) |
| default

Creates an uninitialised oscillator. Call initialise before first use.

## ◆ Oscillator() [2/2]

template<typename SampleType >

juce::dsp::Oscillator< SampleType >::Oscillator | ( | const std::function< NumericType(NumericType)> & | function,
|  | size_t | lookupTableNumPoints = 0 )
| inline

Creates an oscillator with a periodic input function (-pi..pi).

If lookup table is not zero, then the function will be approximated with a lookup table.

Definition at line 51 of file juce_Oscillator.h.

## Member Function Documentation

## ◆ getFrequency()

template<typename SampleType >

NumericType juce::dsp::Oscillator< SampleType >::getFrequency | ( |  | ) | const
| inlinenoexcept

Returns the current frequency of the oscillator.

Definition at line 94 of file juce_Oscillator.h.

## ◆ initialise()

template<typename SampleType >

void juce::dsp::Oscillator< SampleType >::initialise | ( | const std::function< NumericType(NumericType)> & | function,
|  | size_t | lookupTableNumPoints = 0 )
| inline

Initialises the oscillator with a waveform.

## ◆ isInitialised()

template<typename SampleType >

bool juce::dsp::Oscillator< SampleType >::isInitialised | ( |  | ) | const
| inlinenoexcept

Returns true if the Oscillator has been initialised.

Definition at line 58 of file juce_Oscillator.h.

Referenced by juce::dsp::Oscillator< SampleType >::process(), and juce::dsp::Oscillator< SampleType >::processSample().

## ◆ prepare()

template<typename SampleType >

void juce::dsp::Oscillator< SampleType >::prepare | ( | const ProcessSpec & | spec | ) |
| inlinenoexcept

Called before processing starts.

Definition at line 98 of file juce_Oscillator.h.

## ◆ process()

template<typename SampleType >
template<typename ProcessContext >

void juce::dsp::Oscillator< SampleType >::process | ( | const ProcessContext & | context | ) |
| inlinenoexcept

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

Definition at line 126 of file juce_Oscillator.h.

## ◆ processSample()

template<typename SampleType >

SampleType JUCE_VECTOR_CALLTYPE juce::dsp::Oscillator< SampleType >::processSample | ( | SampleType | input | ) |
| inlinenoexcept

Returns the result of processing a single sample.

Definition at line 117 of file juce_Oscillator.h.

## ◆ reset()

template<typename SampleType >

void juce::dsp::Oscillator< SampleType >::reset | ( |  | ) |
| inlinenoexcept

Resets the internal state of the oscillator

Definition at line 107 of file juce_Oscillator.h.

Referenced by juce::dsp::Oscillator< SampleType >::prepare().

## ◆ setFrequency()

template<typename SampleType >

void juce::dsp::Oscillator< SampleType >::setFrequency | ( | NumericType | newFrequency,
|  | bool | force = false )
| inlinenoexcept

Sets the frequency of the oscillator.
