Detailed Description

Provide write access to sound files.

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:

// Create a sound file, ogg/vorbis format, 44100 Hz, stereo
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());
}
