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("music.ogg", 44100, 2, {sf::SoundChannel::FrontLeft, sf::SoundChannel::FrontRight});
while (...)
{
// Read or generate audio samples from your custom source
std::vector<std::int16_t> samples = ...;
// Write them to the file
file.write(samples.data(), samples.size());
}

Constructor & Destructor Documentation

◆ OutputSoundFile() [1/2]

sf::OutputSoundFile::OutputSoundFile ( )
default

Default constructor.

Construct an output sound file that is not associated with a file to write.

◆ OutputSoundFile() [2/2]

sf::OutputSoundFile::OutputSoundFile ( const std::filesystem::path & filename,
unsigned int sampleRate,
unsigned int channelCount,
const std::vector< SoundChannel > & channelMap )

Construct the sound file from the disk for writing.

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

Parameters
filenamePath of the sound file to write
sampleRateSample rate of the sound
channelCountNumber of channels in the sound
channelMapMap of position in sample frame to sound channel
Exceptions
sf::Exceptionif the file could not be opened successfully

Member Function Documentation

◆ close()

void sf::OutputSoundFile::close ( )

Close the current file.

◆ openFromFile()

bool sf::OutputSoundFile::openFromFile ( const std::filesystem::path & filename,
unsigned int sampleRate,
unsigned int channelCount,
const std::vector< SoundChannel > & channelMap )
nodiscard

Open the sound file from the disk for writing.

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

Parameters
filenamePath of the sound file to write
sampleRateSample rate of the sound
channelCountNumber of channels in the sound
channelMapMap of position in sample frame to sound channel
Returns
true if the file was successfully opened

◆ write()

void sf::OutputSoundFile::write ( const std::int16_t * samples,
std::uint64_t count )

Write audio samples to the file.

Parameters
samplesPointer to the sample array to write
countNumber of samples to write
