GSM 06.10 Lossy Speech Compressor Library and Utilities
This package is based on the package 'libgsm' from project 'openSUSE:Factory'.
Contains libraries and binaries for a GSM speech compressor. libgsm
contains a standard 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, which is 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 modeled after compress(1)
and a library API. Compression and decompression run faster than
real-time on most SPARC stations. The implementation has been verified
against the ETSI standard test patterns.

(revision 21)
- Update to version 1.0.18
* Remove the MacOS "quarantine" files that I didn't know I'd
shipped.
* Remove some trailing spaces.
* Bump up the patchlevel in inc/gsm.h (I'd forgotten that in
release 17.)
- Changes from version 1.0.17
* New email addresses in the README.
* Avoid left-shifting signed integers.
* Don't print longwords using %d or %ld, cast them to (long)
first.
* Don't compare longwords as longs in addtest, we only care for
the lower 32 bits. (The math works, but the test failed).
- Changes from version 1.0.16
* New email addresses in the manual pages (patch 16).
* Removed a stray .orig file (in patch 15).
- Rebase libgsm-1.0.13.patch.
- Drop libgsm-strict-aliasing.patch: Applied upstream.
- Drop ancient Obsoletes/Provides.
