/// \class sf::SoundFileReader
/// \ingroup audio
///
/// This class allows users to read audio file formats not natively
/// supported by SFML, and thus extend the set of supported readable
/// audio formats.
///
/// A valid sound file reader must override the open, seek and write functions,
/// as well as providing a static check function; the latter is used by
/// SFML to find a suitable writer for a given input file.
///
/// To register a new reader, use the sf::SoundFileFactory::registerReader
/// template function.
///
/// Usage example:
/// \code
/// class MySoundFileReader : public sf::SoundFileReader
/// {
/// public:
///
/// static bool check(sf::InputStream& stream)
/// {
/// // typically, read the first few header bytes and check fields that identify the format
/// // return true if the reader can handle the format
/// }
///
/// virtual bool open(sf::InputStream& stream, Info& info)
/// {
/// // read the sound file header and fill the sound attributes
/// // (channel count, sample count and sample rate)
/// // return true on success
/// }
///
/// virtual void seek(sf::Uint64 sampleOffset)
/// {
/// // advance to the sampleOffset-th sample from the beginning of the sound
/// }
///
/// virtual sf::Uint64 read(sf::Int16* samples, sf::Uint64 maxCount)
/// {
/// // read up to 'maxCount' samples into the 'samples' array,
/// // convert them (for example from normalized float) if they are not stored
/// // as 16-bits signed integers in the file
/// // return the actual number of samples read
/// }
/// };
