Detailed Description

Wrapper class to continuously stream audio from an audio source to an AudioIODevice.

This object acts as an AudioIODeviceCallback, so can be attached to an output device, and will stream audio from an AudioSource.

Constructor & Destructor Documentation

◆ AudioSourcePlayer()

juce::AudioSourcePlayer::AudioSourcePlayer ( )

Creates an empty AudioSourcePlayer.

◆ ~AudioSourcePlayer()

virtual juce::AudioSourcePlayer::~AudioSourcePlayer ( )
virtual

Destructor.

Make sure this object isn't still being used by an AudioIODevice before deleting it!

Member Function Documentation

◆ setSource()

void juce::AudioSourcePlayer::setSource ( AudioSource newSource)

Changes the current audio source to play from.

If the source passed in is already being used, this method will do nothing. If the source is not null, its prepareToPlay() method will be called before it starts being used for playback.

If there's another source currently playing, its releaseResources() method will be called after it has been swapped for the new one.

Parameters
newSourcethe new source to use - this will NOT be deleted by this object when no longer needed, so it's the caller's responsibility to manage it.

◆ getCurrentSource()

AudioSource* juce::AudioSourcePlayer::getCurrentSource ( ) const
noexcept

Returns the source that's playing.

May return nullptr if there's no source.

◆ setGain()

void juce::AudioSourcePlayer::setGain ( float  newGain)
noexcept

Sets a gain to apply to the audio data.

See also
getGain

◆ getGain()

float juce::AudioSourcePlayer::getGain ( ) const
noexcept

Returns the current gain.

◆ audioDeviceIOCallback()

void juce::AudioSourcePlayer::audioDeviceIOCallback ( const float **  inputChannelData,
int  totalNumInputChannels,
float **  outputChannelData,
int  totalNumOutputChannels,
int  numSamples 
)
overridevirtual

Implementation of the AudioIODeviceCallback method.

Implements juce::AudioIODeviceCallback.

◆ audioDeviceAboutToStart()

void juce::AudioSourcePlayer::audioDeviceAboutToStart ( AudioIODevice device)
overridevirtual

Implementation of the AudioIODeviceCallback method.

Implements juce::AudioIODeviceCallback.

◆ audioDeviceStopped()

void juce::AudioSourcePlayer::audioDeviceStopped ( )
overridevirtual

Implementation of the AudioIODeviceCallback method.

Implements juce::AudioIODeviceCallback.

◆ prepareToPlay()

void juce::AudioSourcePlayer::prepareToPlay ( double  sampleRate,
int  blockSize 
)

An alternative method for initialising the source without an AudioIODevice.
