Detailed Description

changes the volume of the audio data periodically and mixes the result with the input signal.

Constructor & Destructor Documentation

Tremolo() [1/2]

HephAudio::Tremolo::Tremolo

(

)

creates a new instance and initializes it with default values.

Tremolo() [2/2]

HephAudio::Tremolo::Tremolo	(	double	depth,
		const Oscillator &	lfo )

creates a new instance and initializes it with the provided values.

Parameters

depth	controls the dry/wet mix ratio. Ranges between 0 and 1.
lfo	low-frequency oscillator.

~Tremolo()

virtual HephAudio::Tremolo::~Tremolo ( )

virtualdefault

releases the resources and destroys the instance.

Member Function Documentation

Name()

virtual std::string HephAudio::Tremolo::Name ( ) const

overridevirtual

gets the name of the audio effect.

Implements HephAudio::AudioEffect.

Process() [1/3]

virtual void HephAudio::Tremolo::Process ( AudioBuffer & buffer, size_t startIndex, size_t frameCount )

overridevirtual

Applies the effect.

Parameters

buffer	contains the audio data which will be processed.
startIndex	index of the first audio frame to process.
frameCount	number of frames to process.

Reimplemented from HephAudio::ModulationEffect.

ProcessST()

virtual void HephAudio::Tremolo::ProcessST ( const AudioBuffer & inputBuffer, AudioBuffer & outputBuffer, size_t startIndex, size_t frameCount )

overrideprotectedvirtual

applies the effect using single thread.

Parameters

inputBuffer	contains the audio data which will be processed.
outputBuffer	contains the processed audio data.
startIndex	index of the first sample to process.
frameCount	number of frames to process.

Implements HephAudio::AudioEffect.

Process() [2/3]

virtual void HephAudio::AudioEffect::Process ( AudioBuffer & buffer )

virtual

Applies the effect.

Parameters

buffer

contains the audio data which will be processed.

Reimplemented from HephAudio::ModulationEffect.

Process() [3/3]

virtual void HephAudio::AudioEffect::Process ( AudioBuffer & buffer, size_t startIndex )

virtual

Applies the effect.

Parameters

buffer	contains the audio data which will be processed.
startIndex	index of the first audio frame to process.

Reimplemented from HephAudio::ModulationEffect.
