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
sf::OutputSoundFile file;
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());
}

◆ ~OutputSoundFile()

sf::OutputSoundFile::~OutputSoundFile ( )

Destructor.

Closes the file if it was still open.

Member Function Documentation

◆ openFromFile()

bool sf::OutputSoundFile::openFromFile	(	const std::string &	filename,
		unsigned int	sampleRate,
		unsigned int	channelCount
	)

Open the sound file from the disk for writing.

The supported audio formats are: WAV, OGG/Vorbis, FLAC.

Parameters

filename	Path of the sound file to write
sampleRate	Sample rate of the sound
channelCount	Number of channels in the sound

Returns: True if the file was successfully opened

◆ write()

void sf::OutputSoundFile::write	(	const Int16 *	samples,
		Uint64	count
	)

Write audio samples to the file.
