Detailed Description

An AudioSource that mixes together the output of a set of other AudioSources.

Input sources can be added and removed while the mixer is running as long as their prepareToPlay() and releaseResources() methods are called before and after adding them to the mixer.

{Audio}

Constructor & Destructor Documentation

◆ MixerAudioSource()

juce::MixerAudioSource::MixerAudioSource ( )

Creates a MixerAudioSource.

◆ ~MixerAudioSource()

juce::MixerAudioSource::~MixerAudioSource ( )
override

Destructor.

Member Function Documentation

◆ addInputSource()

void juce::MixerAudioSource::addInputSource ( AudioSource newInput,
bool  deleteWhenRemoved 
)

Adds an input source to the mixer.

If the mixer is running you'll need to make sure that the input source is ready to play by calling its prepareToPlay() method before adding it. If the mixer is stopped, then its input sources will be automatically prepared when the mixer's prepareToPlay() method is called.

Parameters
newInputthe source to add to the mixer
deleteWhenRemovedif true, then this source will be deleted when no longer needed by the mixer.

◆ getNextAudioBlock()

void juce::MixerAudioSource::getNextAudioBlock ( const AudioSourceChannelInfo )
overridevirtual

Implementation of the AudioSource method.

Implements juce::AudioSource.

◆ prepareToPlay()

void juce::MixerAudioSource::prepareToPlay ( int  samplesPerBlockExpected,
double  sampleRate 
)
overridevirtual

Implementation of the AudioSource method.

This will call prepareToPlay() on all its input sources.

Implements juce::AudioSource.

◆ releaseResources()

void juce::MixerAudioSource::releaseResources ( )
overridevirtual

Implementation of the AudioSource method.

This will call releaseResources() on all its input sources.

Implements juce::AudioSource.

◆ removeAllInputs()

void juce::MixerAudioSource::removeAllInputs ( )

Removes all the input sources.

Any sources which were added by calling addInputSource() with the deleteWhenRemoved flag set will be deleted by this method.

◆ removeInputSource()

void juce::MixerAudioSource::removeInputSource ( AudioSource input)

Removes an input source.

If the source was added by calling addInputSource() with the deleteWhenRemoved flag set, it will be deleted by this method.
