Bitstream

Speex is a patent-free audio compression format designed for speech. The Speex Project aims to lower the barrier of entry for voice applications by providing a free alternative to expensive proprietary speech codecs. Moreover, Speex is well-adapted to Internet applications and provides useful...

The PyOgg project provides a set of python modules for the various streaming formats and protocols defined by the Xiph.Org Foundation.For now, it mostly deals with the Ogg bitstream container and the Vorbis audio codec.

This file contains MATLAB functions, m-files, that do Huffman coding and arithmetic coding of integer (symbol) sequences. Complete coding may be done by calling an easy to use main program (or main function), where input argument is the sequences you want to compress and the output is the...

LLR_DEMOD LLR Demodulator H = LLR_DEMOD_MEX(CONSTELLATION, MAPPING, METHOD) constructs a LLR demodulator object H for a given constellation, mapping and noise variance. The vectors CONSTELLATION and MAPPING are usually generated by using MATLAB Modem Modulation Modem. and contain the complex or...

%SIGMAPPER Mapper% H = SIGMAPPER(CONSTELLATION, MAPPING) constructs a SIGMAPPER object H to% map a bitstream to the points of a signal constellation. The signal% constellation is specified by the vector CONSTELLATION which contains% the real or complex signal points. The mapping is done according...

Gmerlin_avdecoder is a general purpose media decoding library. It was written as a support library for gmerlin, but it can also be used by other applications. You don't even need gmerlin installed, only gavl. Most of it was written completely from scratch, but the sourcetrees of some other great...
