I managed to provide a simple Interface class to use Faust<\/a> in my Arduino Audio Tools<\/a>.<\/p>\n

Faust<\/strong> (Functional Audio Stream) is a functional programming language for sound synthesis and audio processing with a strong focus on the design of synthesizers, musical instruments, audio effects, etc. Faust targets high-performance signal processing applications and audio plug-ins for a variety of platforms and standards.<\/p>\n

The core component of Faust is its compiler<\/strong>. It allows to “translate” any Faust digital signal processing (DSP) specification to a wide range of non-domain specific languages such as C++<\/strong>, C, LLVM bit code, WebAssembly, Rust, etc. In this regard, Faust can be seen as an alternative to C++ but is much simpler and intuitive to learn.<\/p>\n

So we can just generate our DSP C++ Class<\/strong> and use it with the Arduino Audio Tools. A pinch of salt: I noticed that some implementations however are generating arrays that are too big for Microcontrollers<\/strong>!<\/p>\n

Faust Compile Options<\/h2>\n

I suggest to use the following options:<\/p>\n
