glicol_synth: a graph-based audio DSP library written in Rust

glicol_synth is the audio engine of glicol computer music language. It can be used as a standalone audio library, with quite intuitive APIs:

use glicol_synth::{AudioContextBuilder, signal::ConstSig, Message};

fn main() {
let mut context = AudioContextBuilder::<16>::new()
.sr(44100).channels(1).build();

let node_a = context.add_mono_node(ConstSig::new(42.));
context.connect(node_a, context.destination);
println!("first block {:?}", context.next_block());

context.send_msg(node_a, Message::SetToNumber(0, 100.) );
println!("second block, after msg {:?}", context.next_block());
}

Overview

glicol_synth begins with a fork of the dasp_graph crate, written by @mitchmindtree. many features and contents are added:

  • use const generics for a customisable buffer size
  • replace the input from vec to a map, so users can use a node id to select input
  • users can send message to each node in real-time for interaction
  • add a higher level audiocontext for easier APIs
  • many useful audio nodes from oscillators, filters, etc.

See the examples on GitHub for the basic usage.

Modules

Macros

Structs

  • AudioContext
    The audio context that holds a destination and the graph connection
  • AudioContextBuilder
    The builder to build AudioContext
  • AudioContextConfig
    Another option for building AudioContext
  • BoxedNode
    A wrapper around a Box<dyn Node>.
  • BoxedNodeSend
    A wrapper around a Box<dyn Node>.
  • Buffer
    The fixed-size buffer used for processing the graph.
  • Input
    An important part of the Node trait; each Input contains the relevant node id as usize
  • NodeData
    For use as the node weight within a dasp graph. Contains the node and its buffers.
  • Pass
    A simple node that passes an input directly to the output.
  • Processor
  • Sum
    A stateless node that sums each of the inputs onto the output.
  • Sum2
