+ GSM 06.10 13 kbit/s RPE/LTP speech compression available
+ --------------------------------------------------------
+
+ The Communications and Operating Systems Research Group (KBS) at the
+ Technische Universitaet Berlin is currently working on a set of
+ UNIX-based tools for computer-mediated telecooperation that will be
+ made freely available.
+
+ As part of this effort we are publishing 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; for compatibility
+ with typical UNIX applications, our implementation turns frames of 160
+ 16-bit linear samples into 33-byte frames (1650 Bytes/s).
+ The quality of the algorithm is good enough for reliable speaker
+ recognition; even music often survives transcoding in recognizable
+ form (given the bandwidth limitations of 8 kHz sampling rate).
+
+ The interfaces offered are a front end modelled after compress(1), and
+ a library API. Compression and decompression run faster than realtime
+ on most SPARCstations. The implementation has been verified against the
+ ETSI standard test patterns.
