Detailed Description

An AudioSource which takes another source as input, and buffers it using a thread.

Create this as a wrapper around another thread, and it will read-ahead with a background thread to smooth out playback. You can either create one of these directly, or use it indirectly using an AudioTransportSource.

Constructor & Destructor Documentation

◆ BufferingAudioSource()

BufferingAudioSource::BufferingAudioSource ( PositionableAudioSource * source,
TimeSliceThread & backgroundThread,
bool deleteSourceWhenDeleted,
int numberOfSamplesToBuffer,
int numberOfChannels = 2,
bool prefillBufferOnPrepareToPlay = true )

Creates a BufferingAudioSource.

Parameters
sourcethe input source to read from
backgroundThreada background thread that will be used for the background read-ahead. This object must not be deleted until after any BufferingAudioSources that are using it have been deleted!
deleteSourceWhenDeletedif true, then the input source object will be deleted when this object is deleted
numberOfSamplesToBufferthe size of buffer to use for reading ahead
numberOfChannelsthe number of channels that will be played
prefillBufferOnPrepareToPlayif true, then calling prepareToPlay on this object will block until the buffer has been filled

◆ ~BufferingAudioSource()

BufferingAudioSource::~BufferingAudioSource ( )
override

Destructor.

The input source may be deleted depending on whether the deleteSourceWhenDeleted flag was set in the constructor.
