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)
