Auxide

A real-time-safe, deterministic audio graph kernel for Rust.
Build reliable audio tools, DSP chains, and synthesis engines with a focus on correctness, performance, and simplicity.

Overview

Auxide is a real-time-safe, deterministic audio graph kernel for Rust. It provides the foundation for building reliable audio tools, DSP chains, and synthesis engines with a focus on correctness, performance, and simplicity.

Key Features

• Real-time Safe: Zero allocations in audio processing paths
• Deterministic: Predictable, reproducible audio output
• Graph-based: Flexible node-based audio processing architecture
• Rust Native: Built for Rust's ownership and borrowing system
• Extensible: Plugin architecture for custom nodes

Usage

Add to your Cargo.toml:

[dependencies]
auxide = "0.3"

Example

use auxide::{AudioGraph, NodeType, NodeId, ProcessContext};

// Create a simple audio graph
let mut graph = AudioGraph::new(44100.0, 512);

// Add nodes to the graph
let sine_node = graph.add_node(NodeType::SineOsc { freq: 440.0 })?;
let output_node = graph.add_node(NodeType::Output { channels: 2 })?;

// Connect nodes
graph.connect(sine_node, output_node)?;

// Process audio
let mut buffer = vec![0.0; 512];
graph.process(&mut buffer)?;

Architecture

Auxide uses a pull-based graph execution model where each node processes audio on demand. This ensures:

• No buffer copying between nodes
• Minimal latency
• Efficient CPU usage
• Deterministic execution order
