Introduction

Preamble

Welcome 🦊

If you’re reading this, it’s likely because you care about how sound is made — not just what it sounds like, but how it emerges from code, from structure, from thought.

Devalang is not just a language. It’s an approach to sound. A way to compose audio with clarity, to experiment with rhythm and time, and to speak music fluently.

What is Devalang?

Devalang is a domain-specific language (DSL) built for audio composition and live performance.

It lets you define instruments, patterns, effects, and timing—all using a clear, musical syntax that feels natural to both musicians and programmers.

Core Strengths

• Declarative Syntax

  Describe what should happen, letting Devalang handle the details.
• Real-Time Audio

  Render, perform, and modify music live without waiting for exports.
• Modular & Reusable

  Build sound components once, use them everywhere.
• Cross-Platform

  WebAssembly-native: runs on Windows, macOS, Linux, and browsers.

Why Devalang?

Traditional DAWs excel at visual composition but lack code-like flexibility. Most music programming languages are verbose and disconnected from the sound design process. Devalang bridges this gap.

The Benefits

• Fast Prototyping: Write a beat in seconds without UI navigation
• Readable Code: Even after months away, your music code stays clear
• Precision Control: Every parameter is accessible and composable
• Live Performance: Modify patterns on-the-fly during a set
• Infinite Scalability: From a simple kick loop to generative symphonies

Your First Sound

Ready to hear what Devalang does? Here’s a minimal example:

This creates a simple sine wave synthesizer and plays two quarter-note C2s. In Devalang, every element chains naturally—no boilerplate.
