Function Documentation

◆ rocalAudioFileSource()

RocalTensor ROCAL_API_CALL rocalAudioFileSource	(	RocalContext	context,
		const char *	source_path,
		const char *	source_file_list_path,
		unsigned	shard_count,
		bool	is_output,
		bool	shuffle = `false`,
		bool	loop = `false`,
		bool	downmix = `false`
	)

Creates Audio file reader and decoder. It allocates the resources and objects required to read and decode audio files stored on the file systems. It has internal sharding capability to load/decode in parallel if user wants. If the files are not in standard audio compression formats they will be ignored, Currently wav format is supported

Parameters

[in]	context	Rocal context
[in]	source_path	A NULL terminated char string pointing to the location on the disk
[in]	source_file_list_path	A char string pointing to the file list location on the disk
[in]	shard_count	Defines the parallelism level by internally sharding the input dataset and load/decode using multiple decoder/loader instances. Using shard counts bigger than 1 improves the load/decode performance if compute resources (CPU cores) are available.
[in]	is_output	Boolean variable to enable the audio to be part of the output.
[in]	shuffle	Boolean variable to shuffle the dataset.
[in]	loop	Boolean variable to indefinitely loop through audio.
[in]	downmix	Boolean variable to downmix all input channels to mono. If downmixing is turned on, the decoder output is 1D. If downmixing is turned off, it produces 2D output with interleaved channels incase of multichannel audio.

Returns: Reference to the output audio
