liquid-dsp is a free and open-source digital signal processing (DSP) library designed specifically for software defined radios on embedded platforms. The aim is to provide a lightweight DSP library that does not rely on a myriad of external dependencies or proprietary and otherwise cumbersome frameworks. All signal processing elements are designed to be flexible, scalable, and dynamic, including filters, filter design, oscillators, modems, synchronizers, and complex mathematical operations.

This is the GNU Objective-C++ compiler, which compiles Objective-C++ on platforms supported by the gcc compiler. It uses the gcc backend to generate optimized code.

FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge.

This library offers helper functions to integrate the use of Akonadi calendar items in applications.

Library needed for GNU Go applications linked against the shared library.

Zyan Core is an internal library providing platform independent types, macros and a fallback for environments without LibC.
