frame_type_desc Struct Reference

Description of frame types. More...

Data Fields
uint8_t	n_blocks
	amount of blocks per frame (each block (contains 160/n_blocks samples)
uint8_t	log_n_blocks
	log2(n_blocks)
uint8_t	acb_type
	Adaptive codebook type (ACB_TYPE_*)
uint8_t	fcb_type
	Fixed codebook type (FCB_TYPE_*)
uint8_t	dbl_pulses
	how many pulse vectors have pulse pairs (rather than just one single pulse) only if fcb_type == FCB_TYPE_EXC_PULSES
uint16_t	frame_size
	the amount of bits that make up the block data (per frame)
