## 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

  source | the input source to read from
  backgroundThread | a 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!
  deleteSourceWhenDeleted | if true, then the input source object will be deleted when this object is deleted
  numberOfSamplesToBuffer | the size of buffer to use for reading ahead
  numberOfChannels | the number of channels that will be played
  prefillBufferOnPrepareToPlay | if 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.

void BufferingAudioSource::getNextAudioBlock | ( | const AudioSourceChannelInfo & |  | ) |
| override virtual

Implementation of the AudioSource method.

Implements AudioSource.

## ◆ setNextReadPosition()

void BufferingAudioSource::setNextReadPosition | ( | int64 | newPosition | ) |
| override virtual

Implements the PositionableAudioSource method.

Implements PositionableAudioSource.

## ◆ getNextReadPosition()

int64 BufferingAudioSource::getNextReadPosition | ( |  | ) | const
| override virtual

Implements the PositionableAudioSource method.

Implements PositionableAudioSource.

## ◆ getTotalLength()

int64 BufferingAudioSource::getTotalLength | ( |  | ) | const
| override virtual

Implements the PositionableAudioSource method.

Implements PositionableAudioSource.

## ◆ isLooping()

bool BufferingAudioSource::isLooping | ( |  | ) | const
| override virtual

Implements the PositionableAudioSource method.

Implements PositionableAudioSource.

## ◆ waitForNextAudioBlockReady()

bool BufferingAudioSource::waitForNextAudioBlockReady | ( | const AudioSourceChannelInfo & | info,
|  | uint32 | timeout )

A useful function to block until the next the buffer info can be filled.

This is useful for offline rendering.
