creates a new instance and initializes it with default values.

~DoubleBufferedAudioEffect()

virtual HephAudio::DoubleBufferedAudioEffect::~DoubleBufferedAudioEffect ( )

virtualdefault

releases the resources and destroys the instance.

Member Function Documentation

Process() [1/3]

virtual void HephAudio::DoubleBufferedAudioEffect::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::AudioEffect.

Reimplemented in HephAudio::Flanger, HephAudio::ModulationEffect, HephAudio::OlaEffect, HephAudio::Spatializer, HephAudio::Tremolo, and HephAudio::Vibrato.

CreateOutputBuffer()

virtual AudioBuffer HephAudio::DoubleBufferedAudioEffect::CreateOutputBuffer ( const AudioBuffer & inputBuffer, size_t startIndex, size_t frameCount ) const

protectedvirtual

creates the output buffer but does not initialize it.

Parameters

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

Reimplemented in HephAudio::ChannelMapper, and HephAudio::Resampler.

InitializeOutputBuffer()

virtual void HephAudio::DoubleBufferedAudioEffect::InitializeOutputBuffer ( const AudioBuffer & inputBuffer, AudioBuffer & outputBuffer, size_t startIndex, size_t frameCount ) const

protectedvirtual

initializes the output buffer.

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.

Reimplemented in HephAudio::ChannelMapper, and HephAudio::Resampler.

Process() [2/3]

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

virtual

Reimplemented from HephAudio::AudioEffect.

Reimplemented in HephAudio::ModulationEffect, HephAudio::OlaEffect, HephAudio::Tremolo, and HephAudio::Vibrato.

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.
