dhwani 0.1.1

A real-time audio processing engine for DAWs
Documentation

Dhwani

Dhwani is a real-time node based audio engine for Digital Audio Workstations (DAWs), written in Rust and designed for low-latency sound processing. It focuses on performance, modular DSP building blocks, and efficient I/O for modern audio applications. The engine is built to power synthesizers, mixers, effects chains, and full DAW backends while maintaining Rust’s guarantees for safety and concurrency.

Meaning

Dhwani (Malayalam: ധ്വനി) means sound. The word is used across multiple Indian languages including Malayalam, Hindi, Kannada, Telugu, and Marathi.

Goals

  • Real-time safe audio processing
  • Modular DSP graph
  • Lock-free audio paths
  • DAW and synth friendly architecture

Use cases

  • DAW audio engine backend
  • Software synthesizers
  • Audio effects processors
  • Embedded audio systems
  • Real-time DSP experimentation
