Faust - DSP to C/C++, Rust, LLVM IR, JAVA, WebAssembly (wast/wasm), Interpreter, SOUL and D compiler
faust [options] file1 [file2 ...]
Faust (Functional Audio Stream) is a functional programming language specifically designed for real-time signal processing and synthesis. Faust targets high-performance signal processing applications and audio plug-ins for a variety of platforms and standards.
-a <file> wrapper architecture file.
-i –inline-architecture-files inline architecture files.
-A <dir> –architecture-dir <dir> add the directory <dir> to the architecture search path.
-I <dir> –import-dir <dir> add the directory <dir> to the import search path.
-L <file> –library <file> link with the LLVM module <file>.
-t <sec> –timeout <sec> abort compilation after <sec> seconds (default 120).
-o <file> the output file.
-e –export-dsp export expanded DSP (with all included libraries).
-uim –user-interface-macros add user interface macro definitions to the output code.
-xml generate an XML description file.
-json generate a JSON description file.
-O <dir> –output-dir <dir> specify the relative directory of the generated output code and of additional generated files (SVG, XML...).
-lang <lang> –language select output language, `lang' should be c, ocpp, cpp (default), rust, java, llvm, fir, wast/wasm, soul, interp or dlang.
-single –single-precision-floats use single precision floats for internal computations (default).
-double –double-precision-floats use double precision floats for internal computations.
-quad –quad-precision-floats use quad precision floats for internal computations.
-es 1|0 –enable-semantics 1|0 use enable semantics when 1 (default), and simple multiplication otherwise.
-lcc –local-causality-check check causality also at local level.
-light –light-mode do not generate the entire DSP API.
-clang –clang when compiled with clang/clang++, adds specific #pragma for auto-vectorization.
