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)
