////////////////////////////////////////////////////////////
/// \class sf::SoundFileFactory
/// \ingroup audio
///
/// This class is where all the sound file readers and writers are
/// registered. You should normally only need to use its registration
/// and unregistration functions; readers/writers creation and manipulation
/// are wrapped into the higher-level classes sf::InputSoundFile and
/// sf::OutputSoundFile.
///
/// To register a new reader (writer) use the sf::SoundFileFactory::registerReader
/// (registerWriter) static function. You don't have to call the unregisterReader
/// (unregisterWriter) function, unless you want to unregister a format before your
/// application ends (typically, when a plugin is unloaded).
///
/// Usage example:
/// \code
/// sf::SoundFileFactory::registerReader<MySoundFileReader>();
/// sf::SoundFileFactory::registerWriter<MySoundFileWriter>();
/// \endcode
///
/// \see sf::InputSoundFile, sf::OutputSoundFile, sf::SoundFileReader, sf::SoundFileWriter
