Faust (Functional Audio Stream) is a functional programming language for real-time digital signal processing and sound synthesis, developed at GRAME-CNCM. Its compiler translates DSP specifications into efficient code for C++, C, Java, LLVM IR, WebAssembly, Rust, and more, which can be wrapped into standalone apps, mobile apps, and audio plugins (VST, AU, LADSPA, PD, SuperCollider, etc.).

Use cases

• write audio effects and synthesizers in a high-level language
• compile DSP code to C++ or WebAssembly
• generate VST or AU audio plugins from one codebase
• build real-time signal processing for iOS and Android apps
• embed a JIT-compiled DSP engine in a C++ program via libfaust
• prototype synthesizers and musical instruments in a web IDE

When to choose

• you need sample-level, high-performance audio DSP code
• you want one DSP source targeting many languages and plugin formats
• you are designing synthesizers, effects, or physical models

When to avoid

• you need a general-purpose programming language
• your project has no audio or signal processing component
• you want an interpreted runtime rather than compiled output
