/* * The function implemented in this module examines a frame of 20 int16_t words * that corresponds to GSM-HR encoder output format, and checks if the unused * upper bits of each int16_t word are cleared as they should be. * This function should be used when reading from ETSI-format *.cod files, * to guard against reading garbage or wrong endian. */ #include <stdint.h> #include "tw_gsmhr.h" int gsmhr_check_encoder_params(const int16_t *params) { if (params[18] & 0xFFFE) return -1; if (params[19] & 0xFFFE) return -1; return gsmhr_check_common_params(params); }
