GNU Mailutils is a rich and powerful protocol-independent mail framework. It contains a series of useful mail libraries, clients, and servers.

This is the gr-audio library, used to connect to audio sources (mic-in) and sinks (speaker-out) ports on a computer. The underlying hardware driver is system and OS dependent and this module should automatically discover the correct one to use. Part of the main gnuradio build.

All the functions for doing digital modulation and demodulation, including bpsk, qpsk, gmsk and ofdm signals. Part of the main gnuradio build.

Handle forward error correction processing in gnuradio. Implements the GNU Radio FEC API, supporting encoders and decoders for no-op dummmy, repetition, and convolutional classes. Part of the main gnuradio build.

Given a function which produces random byte vectors, convert it to a number of your choice (int8/int16/int32/int64/int/float).

Library for Fourier transform techniques used in gnuradio. Uses single precision FFT from libfftw3-single3. Part of the main gnuradio build.
