-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.

- * the short term analysis filter; for simplification the index
- * of this array begins at 0 and ends at 39 for each sub-segment of the
