Half Rate is a speech coding system for GSM, developed in the early 1990s. Since the codec, operating at 5.6 kbit/s, requires half the bandwidth of the Full Rate codec, network capacity for voice traffic is doubled, at the expense of audio quality. The sampling rate is 8 kHz with resolution 13 bit, frame length 160 samples and subframe length 40 samples. GSM Half Rate is specified in ETSI EN 300 969, and uses a form of the VSELP algorithm.
