Documentation

Onda is a language and toolchain for real-time audio programming. These docs cover the path from a first oscillator to reusable processors, declarative signal graphs, host integration, and compiler internals.

Learn the language

Try Onda immediately in the browser playground: edit a patch, compile it, and hear the result without installing anything.

Continue with Getting started to install the CLI, run a local patch, and render audio. Then use the Example cookbook to explore complete programs by topic or open them directly in the playground.

The Language guide is the complete syntax and semantics reference. It covers the program surface, execution rates, types, functions, structs, processors, graphs, generics, events, delegates, printing, and modules.

The Standard library reference is generated directly from the modules embedded in the compiler and lists their functions, structs, processors, parameters, ports, and events.

Use the toolchain

Precompiled releases are available for Linux x64, macOS arm64, and Windows x64. The CLI and editor guide explains compilation, real-time playback, offline rendering, diagnostics, VS Code, Neovim, and the C embedding API.

The C API reference documents the complete libonda surface, including compilation, metadata, instances, processing, events, delegates, printing, snapshots, ownership, and release-SDK linking.

The processor API and ABI reference covers direct hosting of native and WebAssembly processor objects without libonda. It documents storage, entry points, parameters, events, delegates, printing, snapshots, target profiles, and every helper in the shipped onda_processor_abi.h header.

The Web API reference covers the complete public surface of the compiler, artifact, Binaryen backend, and Web Audio npm packages. The same reference is included as api.md in every published package.
