This paper discusses the new LLVM bitcode interface between Faust and Pure which allows direct linkage of Pure code with Faust programs, as well as inlining of Faust code in Pure scripts. The interface makes it much easier to integrate signal processing components written in Faust with the symbolic processing and metaprogramming capabilities provided by the Pure language. It also opens new possibilities to leverage Pure and its LLVM-based JIT (just-in-time) compiler as an interactive frontend for Faust programming.
