Protected Member Functions

 SoundStream ()
 Default constructor.
 
void Initialize (unsigned int ChannelsCount, unsigned int SampleRate)
 Set the audio stream parameters, you must call it before Play()

Private Member Functions

void Launch ()
 Create and run the thread.
 
void Wait ()
 Wait until the thread finishes.
 
void Terminate ()
 Terminate the thread Terminating a thread with this function is not safe, you should rather try to make the thread function terminate by itself.
 
void Pause ()
 Pause the sound.
 
void SetBuffer (const SoundBuffer &Buffer)
 Set the source buffer.
 
void SetPitch (float Pitch)
 Set the sound pitch.
 
void SetVolume (float Volume)
 Set the sound volume.
 
void SetPosition (float X, float Y, float Z)
 Set the sound position (take 3 values).
 
void SetPosition (const Vector3f &Position)
 Set the sound position (take a 3D vector).
 
void SetRelativeToListener (bool Relative)
 Make the sound's position relative to the listener's position, or absolute.
 
void SetMinDistance (float MinDistance)
 Set the minimum distance - closer than this distance, the listener will hear the sound at its maximum volume.
 
void SetAttenuation (float Attenuation)
 Set the attenuation factor - the higher the attenuation, the more the sound will be attenuated with distance from listener.
 
void SetPlayingOffset (float TimeOffset)
 Set the current playing position of the sound.
 
const SoundBufferGetBuffer () const
 Get the source buffer.
 
float GetPitch () const
 Get the pitch.
 
float GetVolume () const
 Get the volume.
 
Vector3f GetPosition () const
 Get the sound position.
 
bool IsRelativeToListener () const
 Tell if the sound's position is relative to the listener's position, or if it's absolute.
 
float GetMinDistance () const
 Get the minimum distance.
 
float GetAttenuation () const
 Get the attenuation factor.
 
void ResetBuffer ()
 Reset the internal buffer.
 

Detailed Description

SoundStream is a streamed sound, ie samples are acquired while the sound is playing.

Use it for big sounds that would require hundreds of MB in memory (see Music), or for streaming sound from the network

Definition at line 44 of file SoundStream.hpp.

Member Enumeration Documentation

Enumeration of the sound states.

Definition at line 52 of file Sound.hpp.

Constructor & Destructor Documentation

virtual sf::SoundStream::~SoundStream ( )
virtual

Virtual destructor.

sf::SoundStream::SoundStream ( )
protected

Default constructor.

Member Function Documentation

unsigned int sf::SoundStream::GetChannelsCount ( ) const

Return the number of channels (1 = mono, 2 = stereo)

Returns
Number of channels
bool sf::SoundStream::GetLoop ( ) const

Tell whether or not the stream is looping.

Returns
True if the music is looping, false otherwise
float sf::SoundStream::GetPlayingOffset ( ) const

Get the current playing position of the stream.

Returns
Current playing position, expressed in seconds
unsigned int sf::SoundStream::GetSampleRate ( ) const

Get the stream sample rate.

Returns
Stream frequency (number of samples per second)
Status sf::SoundStream::GetStatus ( ) const

Get the status of the stream (stopped, paused, playing)

Returns
Current status of the sound
void sf::SoundStream::Initialize ( unsigned int  ChannelsCount,
unsigned int  SampleRate 
)
protected

Set the audio stream parameters, you must call it before Play()

Parameters
ChannelsCount: Number of channels
SampleRate: Sample rate
void sf::SoundStream::Play ( )

Start playing the audio stream.

void sf::SoundStream::SetLoop ( bool  Loop)

Set the stream loop state.

This parameter is disabled by default

Parameters
Loop: True to play in loop, false to play once
void sf::SoundStream::Stop ( )

Stop playing the audio stream.
