+Codec 2 README
+--------------
+
+Codec 2 is an open source 2400 bit/s speech codec (LGPL licensed).
+For more information please see:
+
+    http://rowetel.com/codec2.html
+
+Quickstart
+----------
+
+1/ Listen to Codec 2:
+
+   $ cd codec2/src
+   $ make
+   $ ./c2demo ../raw/hts1a.raw hts1a_c2.raw
+   $ ../script/menu.sh ../raw/hts1a.raw hts1a_c2.raw
+
+   NOTE: For playback testing, menu.sh requires either the 'play',
+   'aplay' or 'ossplay' programs to be installed (see
+   http://sox.sourceforge.net/, http://www.alsa-project.org/, or
+   http://www.opensound.com/ respectively).
+
+2/ Compress and Decompress a file:
+
+   $ ./c2enc ../raw/hts1a.raw hts1a_c2.bit
+   $ ./c2dec hts1a_c2.bit hts1a_c2.raw 
+
+Programs
+--------
+ 
+1/ c2demo encodes a file of speech samples, then decodes them and
+saves the result.
+
+2/ c2enc encodes a file of speech samples to a compressed file of
+encoded bits.
+
+3/ c2dec decodes a compressed file of bits to a file of speech
+samples.
+
+4/ c2sim is a simulation/development version of Codec 2.  It allows
+selective use of the various Codec 2 algorithms.  For example
+switching phase modelling or LSP quantisation on and off.
+
+Debugging
+---------
+
+1/ For dump file support:
+
+  $ cd codec2
+  $ CFLAGS=-DDUMP ./configure
+  $ make clean && make
+
+2/ To use gdb:
+
+  $ $ libtool --mode=execute gdb c2sim
