SOUL

SOUL (SOUnd Language) is a dedicated platform for writing and running ultra-low-latency, real-time Digital Signal Processing (DSP) audio code.

SOUL is an optimized platform designed to modernize audio development: it includes a specialized DSL (Domain-Specific Language) and a high-efficiency runtime. The language, created by Julian Storer, focuses on safety and speed, achieving performance comparable to native C++ via its JIT engine. It uses an actor model with a clear graph/node/stream architecture, simplifying complex audio routing. Crucially, the V1.0 release leverages an intermediate assembly language (HEART) to ensure secure, sandboxed execution without the typical performance overhead, delivering the stability and low latency required for professional audio applications like DAWs (Digital Audio Workstations).
