/// \class sf::SoundBufferRecorder
/// \ingroup audio
///
/// sf::SoundBufferRecorder allows to access a recorded sound
/// through a sf::SoundBuffer, so that it can be played, saved
/// to a file, etc.
///
/// It has the same simple interface as its base class (start(), stop())
/// and adds a function to retrieve the recorded sound buffer
/// (getBuffer()).
///
/// As usual, don't forget to call the isAvailable() function
/// before using this class (see sf::SoundRecorder for more details
/// about this).
///
/// Usage example:
/// \code
/// if (sf::SoundBufferRecorder::isAvailable())
/// {
///     // Record some audio data
///     sf::SoundBufferRecorder recorder;
///     recorder.start();
///     ...
///     recorder.stop();
///
///     // Get the buffer containing the captured audio data
///     const sf::SoundBuffer& buffer = recorder.getBuffer();
///
///     // Save it to a file (for example...)
///     buffer.saveToFile("my_record.ogg");
/// }
/// \endcode
