In summary, writing signal processing applications in the FAUST language is rewarding in several respects. First, the language is high-level, yet it compiles to efficient C++ code. The development cycle is very short, typically involving only (1) syntax debugging, (2) block-diagram inspection, and (3) trying out the app/plugin. When precise verification is required, the output signals can be printed or loaded into Matlab/Octave for detailed analysis. Finally, writing in FAUST makes it very easy to generate applications and plugins for a wide range of hosting environments.
