Binary package “libgsm1-dev” in openkylin nile
Development libraries for a GSM speech compressor
This package contains header files and development libraries for
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 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, this 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.
