Extempore is a live-coding environment for music and audio that pairs a Scheme interpreter with xtlang, a statically-typed lisp compiled to LLVM IR at runtime. It lets programmers reshape a running program while it continues producing sound, running on Linux, macOS, and Windows.
Use cases
- live-code music and audio performances
- reshape a running program while it keeps making sound
- write real-time audio DSP code in a lisp that JIT-compiles via LLVM
- control sound and graphics with OSC messages
- teach or explore cyber-physical programming
- prototype audio algorithms interactively in a REPL
When to choose
- you want a live-coding environment for music and audio with JIT-compiled performance
- you need both a dynamic Scheme layer and statically-typed low-level code in one runtime
- you work across Linux, macOS, or Windows including Apple Silicon and aarch64
- you want WebGPU graphics bindings alongside audio
When to avoid
- you need a general-purpose programming language for non-audio projects
- you want a no-build toolchain without a C++20 compiler when building from source
- you rely on the retired OpenGL graphics stack
- you need a permissively-licensed project and license clarity matters (no license file)
