CSFML_AUDIO_API sfVector3f sfSound_getPosition | ( | const sfSound * | sound) |  |

Get the 3D position of a sound in the audio scene.

CSFML_AUDIO_API sfSoundStatus sfSound_getStatus | ( | const sfSound * | sound) |  |

Get the current status of a sound (stopped, paused, playing)

Parameters

  sound | Sound object

Returns
  Current status

CSFML_AUDIO_API float sfSound_getVolume | ( | const sfSound * | sound) |  |

Get the volume of a sound.

  sound | Sound object

Returns
  Volume of the sound, in the range [0, 100]

CSFML_AUDIO_API sfBool sfSound_isRelativeToListener | ( | const sfSound * | sound) |  |

Tell whether a sound's position is relative to the listener or is absolute.

Parameters

  sound | Sound object

Returns
  sfTrue if the position is relative, sfFalse if it's absolute

CSFML_AUDIO_API void sfSound_pause | ( | sfSound * | sound) |  |

Pause a sound.

This function pauses the sound if it was playing, otherwise (sound already paused or stopped) it has no effect.

Parameters

  sound | Sound object

CSFML_AUDIO_API void sfSound_play | ( | sfSound * | sound) |  |

Start or resume playing a sound.

This function starts the sound if it was stopped, resumes it if it was paused, and restarts it from beginning if it was it already playing. This function uses its own thread so that it doesn't block the rest of the program while the sound is played.

Parameters

  sound | Sound object

CSFML_AUDIO_API void sfSound_setAttenuation | ( | sfSound * | sound,
|  | float | attenuation
| ) |  |

Set the attenuation factor of a sound.

The attenuation is a multiplicative factor which makes the sound more or less loud according to its distance from the listener. An attenuation of 0 will produce a non-attenuated sound, i.e. its volume will always be the same whether it is heard from near or from far. On the other hand, an attenuation value such as 100 will make the sound fade out very quickly as it gets further from the listener. The default value of the attenuation is 1.

Parameters

  sound | Sound object
  attenuation | New attenuation factor of the sound

CSFML_AUDIO_API void sfSound_setBuffer | ( | sfSound * | sound,
|  | const sfSoundBuffer * | buffer
| ) |  |

Set the source buffer containing the audio data to play.

It is important to note that the sound buffer is not copied, thus the sfSoundBuffer object must remain alive as long as it is attached to the sound.

Parameters

  sound | Sound object
  buffer | Sound buffer to attach to the sound

CSFML_AUDIO_API void sfSound_setLoop | ( | sfSound * | sound,
|  | sfBool | loop
| ) |  |

Set whether or not a sound should loop after reaching the end.

If set, the sound will restart from beginning after reaching the end and so on, until it is stopped or sfSound_setLoop(sound, sfFalse) is called. The default looping state for sounds is false.

Parameters

  sound | Sound object
  loop | sfTrue to play in loop, sfFalse to play once

CSFML_AUDIO_API void sfSound_setMinDistance | ( | sfSound * | sound,
|  | float | distance
| ) |  |

Set the minimum distance of a sound.

The "minimum distance" of a sound is the maximum distance at which it is heard at its maximum volume. Further than the minimum distance, it will start to fade out according to its attenuation factor. A value of 0 ("inside the head of the listener") is an invalid value and is forbidden. The default value of the minimum distance is 1.

Parameters

  sound | Sound object
  distance | New minimum distance of the sound

CSFML_AUDIO_API void sfSound_setPitch | ( | sfSound * | sound,
|  | float | pitch
| ) |  |

Set the pitch of a sound.

The pitch represents the perceived fundamental frequency of a sound; thus you can make a sound more acute or grave by changing its pitch. A side effect of changing the pitch is to modify the playing speed of the sound as well. The default value for the pitch is 1.

Parameters

  sound | Sound object
  pitch | New pitch to apply to the sound

CSFML_AUDIO_API void sfSound_setPlayingOffset | ( | sfSound * | sound,
|  | sfTime | timeOffset
| ) |  |

Change the current playing position of a sound.

The playing position can be changed when the sound is either paused or playing.

Parameters

  sound | Sound object
  timeOffset | New playing position

CSFML_AUDIO_API void sfSound_setPosition | ( | sfSound * | sound,
|  | sfVector3f | position
| ) |  |

Set the 3D position of a sound in the audio scene.

Only sounds with one channel (mono sounds) can be spatialized. The default position of a sound is (0, 0, 0).

Parameters

  sound | Sound object
  position | Position of the sound in the scene

CSFML_AUDIO_API void sfSound_setRelativeToListener | ( | sfSound * | sound,
|  | sfBool | relative
| ) |  |

Make the sound's position relative to the listener or absolute.

Making a sound relative to the listener will ensure that it will always be played the same way regardless the position of the listener. This can be useful for non-spatialized sounds, sounds that are produced by the listener, or sounds attached to it. The default value is false (position is absolute).

Parameters

  sound | Sound object
  relative | sfTrue to set the position relative, sfFalse to set it absolute

CSFML_AUDIO_API void sfSound_setVolume | ( | sfSound * | sound,
|  | float | volume
| ) |  |

Set the volume of a sound.

The volume is a value between 0 (mute) and 100 (full volume). The default value for the volume is 100.

Parameters

  sound | Sound object
  volume | Volume of the sound

CSFML_AUDIO_API void sfSound_stop | ( | sfSound * | sound) |  |

Stop playing a sound.

This function stops the sound if it was playing or paused, and does nothing if it was already stopped. It also resets the playing position (unlike sfSound_pause).

Parameters

  sound | Sound object
