Detailed Description

template<FloatType SampleType>
class marvin::dsp::oscillators::NoiseOscillator< SampleType >

A white noise oscillator.

Constructor & Destructor Documentation

NoiseOscillator()

template<FloatType SampleType>

marvin::dsp::oscillators::NoiseOscillator< SampleType >::NoiseOscillator ( std::random_device & rd )

explicit

As it's not recommended to keep multiple instances of std::random_device around, it's necessary to pass one in by reference to the constructor, as a seed for the internal rng.

Parameters

rd	The seed generator to use.

~NoiseOscillator()

Member Function Documentation

operator()() [1/2]

template<FloatType SampleType>

SampleType marvin::dsp::oscillators::NoiseOscillator< SampleType >::operator() ( )

nodiscardoverridevirtualnoexcept

Processes the next sample of the wave, handling phase increments internally. Make sure to call prepareToPlay and setFrequency before calling this function!

Returns

The oscillator's output.

Implements marvin::dsp::oscillators::OscillatorBase< SampleType >.

operator()() [2/2]

template<FloatType SampleType>

SampleType marvin::dsp::oscillators::NoiseOscillator< SampleType >::operator() ( SampleType phase )

nodiscardoverridevirtualnoexcept

As NoiseOscillator has no concept of phase, this overload is exactly identical to the internal phase overload.

Parameters

phase

Unused in this case.

Implements marvin::dsp::oscillators::OscillatorBase< SampleType >.
