Internal Program Version: GSM 1.0.22
Contains binaries for a GSM speech compressor, verified against the
ETSI standard test patterns.
libgsm implements the European GSM 06.10 provisional standard for
full-rate speech transcoding, prI-ETS 300 036, which uses RPE/LTP
(residual pulse excitation/long term prediction) coding at 13 kbit/s.
GSM 06.10 compresses frames of 160 13-bit samples (8 kHz sampling
rate) into 260 bits.
