Description Dominik 'Rathann' Mierzejewski 2007-05-11 04:20:51 EDT
Spec URL: http://rpm.greysector.net/extras/gsm.spec
SRPM URL: http://rpm.greysector.net/extras/gsm-1.0.12-2.src.rpm
Description:

libgsm, 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 162 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.
Comment 1 Michael Schwendt 2007-05-11 11:04:15 EDT
Moving the tools is fine and should have been done long ago.

Based on looking at a unified diff against the previous package
from the %changelog:

APPROVED
