/// \class sf::Sound
/// \ingroup audio
///
/// 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
/// on streaming).
///
/// 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;
/// sound.setBuffer(buffer);
/// sound.play();
/// \endcode
///
/// \see sf::SoundBuffer, sf::Music
