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.
