SUMMARY="GSM 06.10 lossy speech compression library"
DESCRIPTION="
An implementation of 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, i.e. a frame rate of 50 Hz) into 260 bits
The quality of the algorithm is good enough for reliable speaker recognition, even music
