load_audio()

std::shared_ptr< Kakshya::SoundFileContainer > MayaFlux::IO::IOManager::load_audio	(	const std::string &	filepath,
		VideoLoadConfig	config = {}
	)

Load an audio file into a SoundFileContainer.

Performs can_read check, opens the file, creates and populates the container, and configures the default ContiguousAccessProcessor with auto_advance enabled.

Parameters

filepath	Path to the audio file.
config	LoadConfig struct containing audio read options.

Returns

Loaded SoundFileContainer, or nullptr on failure.
