/// sf::Sound is the class to use to play sounds.

|
/// It provides:
|
|
/// \li Control (play, pause, stop)
|
|
/// \li Ability to modify output parameters in real-time (pitch, volume, ...)
|
|
/// \li 3D spatial features (position, attenuation, ...).
|
|
///
|

/// sf::Sound is perfect for playing short sounds that can
|
|
/// fit in memory and require no latency, like foot steps or
|
|
/// gun shots. For longer sounds, like background musics
|
|
/// or long speeches, rather see sf::Music (which is based

|
|
/// In order to work, a sound must be given a buffer of audio
|
|
/// data to play. Audio data (samples) is stored in sf::SoundBuffer,
|
|
/// and attached to a sound with the setBuffer() function.

|
/// The buffer object attached to a sound must remain alive
|
|
/// as long as the sound uses it. Note that multiple sounds
|
|
/// can use the same sound buffer at the same time.

|
|
/// Usage example:
|
|
/// \code
|
|
/// sf::SoundBuffer buffer;
|
|
/// buffer.loadFromFile("sound.wav");

|
///
|

/// sf::Sound sound;
