Half Rate

All you want to know about Half Rate

Half Rate or HR or GSM-HR is a speech encoding 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. Is recommended to use this codec when having low battery. It saves 30% more energy.

GSM Half Rate is specified in ETSI 06.20, and uses a form of the VSELP algorithm.
