This project is meant to generate a subset of the amazing codec2 library containing only the actual speech codec and having no further dependencies than a C99 compiler.

The generate a stripped down version of codec2 that does not need CMake etc, just copy the stripdown.sh file to your codec2 directory and run it. This will generate the directory you see here.

Codec 2 is an open source (LGPL 2.1) low bit rate speech codec:
