Blastlibs is a repository of small, portable libraries intended mostly for use in games. The libraries are written in C and will build on any platform with a C89 compiler unless otherwise specified.
Voclib is an implementation of a traditional channel vocoder which is generally used to add interesting effects to speech. The vocoder is written in C and is distributed as a single header file. It should compile on pretty much any platform with a C89 compiler as long as floats are available.
