Detailed Description

Manages all the changes requested by the main convolution engine, to minimize the number of calls of the convolution engine initialization, and the potential consequences of multiple quick calls to the function Convolution::loadImpulseResponse.

Member Function Documentation

◆ addToFifo() [1/2]

void juce::dsp::Convolution::Pimpl::addToFifo ( ChangeRequest *  types,
juce::var parameters,
int  numEntries 
)
inline

Adds a new array of change requests.

Definition at line 418 of file juce_Convolution.cpp.

◆ addToFifo() [2/2]

void juce::dsp::Convolution::Pimpl::addToFifo ( ChangeRequest  type,
juce::var  parameter 
)
inline

Adds a new change request.

Definition at line 393 of file juce_Convolution.cpp.

◆ copyBufferToTemporaryLocation()

void juce::dsp::Convolution::Pimpl::copyBufferToTemporaryLocation ( dsp::AudioBlock< float block)
inline

This function copies a buffer to a temporary location, so that any external audio source can be processed then in the dedicated thread.

Definition at line 695 of file juce_Convolution.cpp.

Referenced by processFifo().

◆ getNumRemainingEntries()

int juce::dsp::Convolution::Pimpl::getNumRemainingEntries ( ) const
inlinenoexcept

Returns the number of requests that still need to be processed.

Definition at line 470 of file juce_Convolution.cpp.

Referenced by processFifo().

◆ initProcessing()

void juce::dsp::Convolution::Pimpl::initProcessing ( int  maximumBufferSize)
inline

Inits the size of the interpolation buffer.

Definition at line 383 of file juce_Convolution.cpp.

◆ processFifo()

void juce::dsp::Convolution::Pimpl::processFifo ( )
inline

This function processes all the change requests to remove all the the redundant ones, and to tell what kind of initialization must be done.

Depending on the results, the convolution engines might be reset, or simply updated, or they might not need any change at all.

Definition at line 482 of file juce_Convolution.cpp.

Referenced by processSamples(), and reset().

◆ processSamples()

void juce::dsp::Convolution::Pimpl::processSamples ( const AudioBlock< const float > &  input,
AudioBlock< float > &  output 
)
inline

Convolution processing handling interpolation between previous and new states of the convolution engines.

Definition at line 721 of file juce_Convolution.cpp.

Referenced by processSamples().

◆ readFromFifo()

void juce::dsp::Convolution::Pimpl::readFromFifo ( ChangeRequest &  type,
juce::var parameter 
)
inline

Reads requests from the fifo.

Definition at line 449 of file juce_Convolution.cpp.

Referenced by processFifo().

◆ reset()

void juce::dsp::Convolution::Pimpl::reset ( )
inline

Resets the convolution engines states.

Definition at line 708 of file juce_Convolution.cpp.
