dsp-chain Build Status Crates.io Crates.io

A library for chaining together multiple audio dsp processors/generators, written in Rust!

Use cases for dsp-chain include:

  • Designing effects.
  • Creating an audio mixer.
  • Making a sampler.
  • Writing a dsp backend for a DAW.
  • Any kind of modular audio synthesis/processing.

Documenation

API documentation here!

Usage

Here's what it looks like:

// Construct our dsp graph.
let mut graph = Graph::new();

// Construct our fancy Synth and add it to the graph!
let synth = graph.add_node(DspNode::Synth);

// Add a few oscillators as inputs to the synth.
graph.add_input(DspNode::Oscillator(0.0, A5_HZ, 0.2), synth);
graph.add_input(DspNode::Oscillator(0.0, D5_HZ, 0.1), synth);
graph.add_input(DspNode::Oscillator(0.0, F5_HZ, 0.15), synth);

// Set the synth as the master node for the graph.
// This can be inferred by the graph so calling this is optional, but it's nice to be explicit.
graph.set_master(Some(synth));

// Request audio from our Graph.
graph.audio_requested(&mut buffer, settings);

Here are two working examples of using dsp-chain to create a very basic synth and an oscillating volume.
