aaruf_cst_transform()

int32_t aaruf_cst_transform	(	const uint8_t *	interleaved,
		uint8_t *	sequential,
		const size_t	length )

Transforms interleaved subchannel data to sequential format.

Converts interleaved subchannel data into a sequential format for further processing.

Parameters

interleaved	Pointer to the interleaved data buffer.
sequential	Pointer to the output sequential data buffer.
length	Length of the data buffer.

Returns

AARUF_STATUS_OK on success, or an error code on failure.

aaruf_cst_untransform()

int32_t aaruf_cst_untransform	(	const uint8_t *	sequential,
		uint8_t *	interleaved,
		const size_t	length )

Reverses the CST (Claunia's Subchannel Transform) transformation from sequential to interleaved data.

Parameters

sequential	Pointer to the sequential data buffer.
interleaved	Pointer to the output buffer for interleaved data.
