/// \class sf::SoundBuffer
/// \ingroup audio
///
/// A sound buffer holds the data of a sound, which is
/// an array of audio samples. A sample is a 16 bits signed integer
/// that defines the amplitude of the sound at a given time.
/// The sound is then reconstituted by playing these samples at
/// a high rate (for example, 44100 samples per second is the
/// standard rate used for playing CDs). In short, audio samples
/// are like texture pixels, and a sf::SoundBuffer is similar to
/// a sf::Texture.
///
/// A sound buffer can be loaded from a file (see loadFromFile()
/// for the complete list of supported formats), from memory, from
/// a custom stream (see sf::InputStream) or directly from an array
/// of samples. It can also be saved back to a file.
///
/// Sound buffers alone are not very useful: they hold the audio data
/// but cannot be played. To do so, you need to use the sf::Sound class,
/// which provides functions to play/pause/stop the sound as well as
/// changing the way it is outputted (volume, pitch, 3D position, ...).
/// This separation allows more flexibility and better performances:
/// indeed a sf::SoundBuffer is a heavy resource, and any operation on it
/// is slow (often too slow for real-time applications). On the other
/// side, a sf::Sound is a lightweight object, which can use the audio data
/// of a sound buffer and change the way it is played without actually
/// modifying that data. Note that it is also possible to bind
/// several sf::Sound instances to the same sf::SoundBuffer.
///
/// It is important to note that the sf::Sound instance doesn't
/// copy the buffer that it uses, it only keeps a reference to it.
/// Thus, a sf::SoundBuffer must not be destructed while it is
/// used by a sf::Sound (i.e. never write a function that
/// uses a local sf::SoundBuffer instance for loading a sound).
///
/// Usage example:
/// \code
/// // Declare a new sound buffer
/// sf::SoundBuffer buffer;
///
/// // Load it from a file
/// if (!buffer.loadFromFile("sound.wav"))
/// {
/// // error...
/// }
///
/// // Create a sound source and bind it to the buffer
/// sf::Sound sound1;
/// sound1.setBuffer(buffer);
///
/// // Play the sound
/// sound1.play();
///
/// // Create another sound source bound to the same buffer
/// sf::Sound sound2;
/// sound2.setBuffer(buffer);
///
/// // Play it with a higher pitch -- the first sound remains unchanged
/// sound2.setPitch(2);
/// sound2.play();
/// \endcode
///
/// \see sf::Sound, sf::SoundBufferRecorder

/// \class sf::SoundRecorder
/// \ingroup audio
///
/// sf::SoundBuffer provides a simple interface to access
/// the audio recording capabilities of the computer
/// (the microphone). As an abstract base class, it only cares
/// about capturing sound samples, the task of making something
/// useful with them is left to the derived class. Note that
/// SFML provides a built-in specialization for saving the
/// captured data to a sound buffer (see sf::SoundBufferRecorder).
///
/// A derived class has only one virtual function to override:
/// \li onProcessSamples provides the new chunks of audio samples while the capture happens
///
/// Moreover, two additional virtual functions can be overridden
/// as well if necessary:
/// \li onStart is called before the capture happens, to perform custom initializations
/// \li onStop is called after the capture ends, to perform custom cleanup
///
/// A derived class can also control the frequency of the onProcessSamples
/// calls, with the setProcessingInterval protected function. The default
/// interval is chosen so that recording thread doesn't consume too much
/// CPU, but it can be changed to a smaller value if you need to process
/// the recorded data in real time, for example.
///
/// The audio capture feature may not be supported or activated
/// on every platform, thus it is recommended to check its
/// availability with the isAvailable() function. If it returns
/// false, then any attempt to use an audio recorder will fail.
///
/// If you have multiple sound input devices connected to your
/// computer (for example: microphone, external soundcard, webcam mic, ...)
/// you can get a list of all available devices through the
/// getAvailableDevices() function. You can then select a device
/// by calling setDevice() with the appropriate device. Otherwise
/// the default capturing device will be used.
///
/// It is important to note that the audio capture happens in a
/// separate thread, so that it doesn't block the rest of the
/// program. In particular, the onProcessSamples virtual function
/// (but not onStart and not onStop) will be called
/// from this separate thread. It is important to keep this in
/// mind, because you may have to take care of synchronization
/// issues if you share data between threads.
///
/// Usage example:
/// \code
/// class CustomRecorder : public sf::SoundRecorder
/// {
/// virtual bool onStart() // optional
/// {
/// // Initialize whatever has to be done before the capture starts
/// ...
///
/// // Return true to start playing
/// return true;
/// }
///
/// virtual bool onProcessSamples(const Int16* samples, std::size_t sampleCount)
/// {
/// // Do something with the new chunk of samples (store them, send them, ...)
/// ...
///
/// // Return true to continue playing
/// return true;
/// }
///
/// virtual void onStop() // optional
/// {
/// // Clean up whatever has to be done after the capture ends
/// ...
/// }
/// }
///
/// // Usage
/// if (CustomRecorder::isAvailable())
/// {
/// CustomRecorder recorder;
///
/// if (!recorder.start())
/// return -1;
///
/// ...
/// recorder.stop();
/// }

/// \class sf::SoundStream
/// \ingroup audio
///
/// Unlike audio buffers (see sf::SoundBuffer), audio streams
/// are never completely loaded in memory. Instead, the audio
/// data is acquired continuously while the stream is playing.
/// This behavior allows to play a sound with no loading delay,
/// and keeps the memory consumption very low.
///
/// Sound sources that need to be streamed are usually big files
/// (compressed audio musics that would eat hundreds of MB in memory)
/// or files that would take a lot of time to be received
/// (sounds played over the network).
///
/// sf::SoundStream is a base class that doesn't care about the
/// stream source, which is left to the derived class. SFML provides
/// a built-in specialization for big files (see sf::Music).
/// No network stream source is provided, but you can write your own
/// by combining this class with the network module.
///
/// A derived class has to override two virtual functions:
/// \li onGetData fills a new chunk of audio data to be played
/// \li onSeek changes the current playing position in the source
///
/// It is important to note that each SoundStream is played in its
/// own separate thread, so that the streaming loop doesn't block the
/// rest of the program. In particular, the OnGetData and OnSeek
/// virtual functions may sometimes be called from this separate thread.
/// It is important to keep this in mind, because you may have to take
/// care of synchronization issues if you share data between threads.
///
/// Usage example:
/// \code
/// class CustomStream : public sf::SoundStream
/// {
/// public:
///
/// bool open(const std::string& location)
/// {
/// // Open the source and get audio settings
/// ...
/// unsigned int channelCount = ...;
/// unsigned int sampleRate = ...;
///
/// // Initialize the stream -- important!
/// initialize(channelCount, sampleRate);
/// }
///
/// private:
///
/// virtual bool onGetData(Chunk& data)
/// {
/// // Fill the chunk with audio data from the stream source
/// // (note: must not be empty if you want to continue playing)
/// data.samples = ...;
/// data.sampleCount = ...;
///
/// // Return true to continue playing
/// return true;
/// }
///
/// virtual void onSeek(Uint32 timeOffset)
/// {
/// // Change the current position in the stream source
/// ...
/// }
/// }
///
/// // Usage
/// CustomStream stream;
/// stream.open("path/to/stream");
/// stream.play();
/// \endcode
