Important note: if you are looking for the graphical application based on this library, it has been deprecated and removed from the source tree. Suscan (GUI) was a GTK3-based application with poor performance and responsiveness that was eventually replaced by the Qt5 application SigDigger. You will still need Suscan (library) in order to compile SigDigger.

Suscan is a realtime DSP processing library. It provides a set of useful abstractions to perform dynamic digital signal analysis and demodulation. Suscan offers features like:

• Multicore-friendly signal processing, based on worker threads
• Generic ASK, FSK, PSK and audio demodulators
• An extensible codec interface
• Configuration file API (XML)
• Source API based on SoapySDR

In order to build Suscan, you will need the development files for the following packages:

sigutils fftw3 sndfile SoapySDR libxml

If you are in a Debian-like operating system, you will also need autoconf, automake, libtool and build-essential.

After installing all dependencies, Suscan can be compiled executing the following commands:

% ./autogen.sh
% ,/configure
% make
% sudo make install
% sudo ldconfig

You can verify your installation by running:

% suscan

If everything went fine, you should see the message:

suscan: suscan library loaded successfully.
