/* Storage for audio samples defining a sound.
|
||||
*
|
||||
* 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
|
||||
* restituted 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 image pixels, and a SFML::SoundBuffer is similar to a SFML::Image.
|
||||
*
|
||||
* A sound buffer can be loaded from a file (see loadFromFile() for the complete list of supported formats), from
|
||||
* memory 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 SFML::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 SFML::SoundBuffer is a heavy resource, and any operation on it is slow (often too slow for real-time
|
||||
* applications). On the other side, a SFML::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 SFML::Sound instances to the same SFML::SoundBuffer.
|
||||
*
|
||||
* It is important to note that the SFML::Sound instance doesn't copy the buffer that it uses, it only keeps a reference
|
||||
* to it. Thus, a SFML::SoundBuffer must not be destructed while it is used by a SFML::Sound (i.e. never write a function
|
||||
* that uses a local SFML::SoundBuffer instance for loading a sound).
|
||||
*
|
||||
* Usage example:
|
||||
*
|
||||
* # Declare a new sound buffer
|
||||
* buffer = SFML::SoundBuffer.new
|
||||
*
|
||||
* # Load it from a file
|
||||
* if buffer.loadFromFile( "sound.wav" ) == false
|
||||
* # error...
|
||||
* end
|
||||
*
|
||||
* # Create a sound source and bind it to the buffer
|
||||
* sound1 = SFML::Sound.new
|
||||
* sound1.setBuffer( buffer )
|
||||
*
|
||||
* # Play the sound
|
||||
* sound1.play()
|
||||
*
|
||||
* # Create another sound source bound to the same buffer
|
||||
* sound2 = SFML::Sound.new
|
||||
* sound2.setBuffer( buffer )
|
||||
*
|
||||
* # Play it with a higher pitch -- the first sound remains unchanged
|
||||
* sound2.setPitch( 2 )
|
||||
* sound2.play()

/* Abstract base class for streamed audio sources.
|
||||
*
|
||||
* Unlike audio buffers (see SFML::SoundBuffer), audio streams are never completely loaded in memory.
|
||||
*
|
||||
* Instead, the audio data is acquired continuously while the stream is playing. This behaviour 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).
|
||||
*
|
||||
* SFML::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 SFML::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:
|
||||
*
|
||||
* - onGetData fills a new chunk of audio data to be played
|
||||
* - 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:
|
||||
*
|
||||
* class CustomStream < SFML::SoundStream
|
||||
* def open( location )
|
||||
* # Open the source and get audio settings
|
||||
* ...
|
||||
* channelsCount = ...
|
||||
* sampleRate = ...
|
||||
*
|
||||
* # Initialize the stream -- important!
|
||||
* initialize( channelsCount, sampleRate )
|
||||
* end
|
||||
*
|
||||
* def onGetData( data )
|
||||
* # Fill the chunk with audio data from the stream source
|
||||
* data.Samples = ...;
|
||||
* data.NbSamples = ...;
|
||||
*
|
||||
* # Return true to continue playing
|
||||
* return true;
|
||||
* end
|
||||
*
|
||||
* def onSeek( timeOffset )
|
||||
* # Change the current position in the stream source
|
||||
* ...
|
||||
* end
|
||||
* end
|
||||
*
|
||||
* # Usage
|
||||
* CustomStream stream;
|
||||
* stream.open( "path/to/stream" )
|
||||
* stream.play
