Signal Applications To Audio Networks is a program aimed at different signal processing tasks. The primary type of signals are audio signals. The user describes networks of different modules using a special language, and the modules are dynamically loaded libraries. The system can be used to create music from scratch, or to process already created audio files, and depending on the complexity of the network versus the capacity of the host machine, everything can be done in "real time".
