/// \class sf::OutputSoundFile

///
/// This class encodes audio samples to a sound file. It is
/// used internally by higher-level classes such as sf::SoundBuffer,
/// but can also be useful if you want to create audio files from
/// custom data sources, like generated audio samples.
///
/// Usage example:
/// \code
/// // Create a sound file, ogg/vorbis format, 44100 Hz, stereo
/// sf::OutputSoundFile file;
/// if (!file.openFromFile("music.ogg", 44100, 2))
///     /* error */;
///
/// while (...)
/// {
///     // Read or generate audio samples from your custom source
///     std::vector<sf::Int16> samples = ...;
///
///     // Write them to the file
///     file.write(samples.data(), samples.size());
/// }
/// \endcode
