A Rust environment for sound synthesis and algorithmic composition, powered by [SuperCollider](https://supercollider.github.io/).

![Sorceress](https://raw.githubusercontent.com/ooesili/sorceress/master/assets/sorceress.svg)

## Overview

Sorceress is a Rust crate that provides a creative coding environment for:

* **Sound synthesis** - build audio synthesizers by connecting *unit generators* together into signal graphs. SuperCollider provides [hundreds of unit generators](https://doc.sccode.org/Browse.html#UGens) to choose from including things like wave generators, noise generators, filters, envelopes, compressors, resonators, physical simulations, Fourier transforms, and much more.

* **Algorithmic composition** - write code to create music, anywhere from using code as a musical notation system to full-fledged generative composition where large scale structures of a music piece are determined by computational algorithms.

### Why SuperCollider?

SuperCollider is a powerful and mature platform for audio synthesis with decades of development effort behind it. SuperCollider's [Client and Server](https://doc.sccode.org/Guides/ClientVsServer.html) architecture lets us to leverage all of the features offered by SuperCollider's audio synthesis server, from Rust:

* A real-time audio synthesis engine
* A massive library of unit generators
* Audio I/O with your operation system and sound card

### Why Rust?

There are projects in many other programming languages for interacting with SuperCollider including [Overtone](https://overtone.github.io/), [Tidal](https://tidalcycles.org/), and [Sonic Pi](https://sonic-pi.net/). I really like programming in Rust and I could not find any such project using Rust so I started building Sorceress.

## Example

This example plays a sine wave at 220 Hz for 1 second:

```rust
use sorceress::{
    server::{self, Result, Server},
    synthdef::{encoder::encode_synth_defs, SynthDef},
    ugen,
};
use std::{thread::sleep, time::Duration};

fn main() -> Result<()> {
    let server = Server::connect("127.0.0.1:57110")?;

let sine_wave = SynthDef::new("sine_wave", |_| {
        ugen::Out::ar().channels(ugen::Pan2::ar().input(ugen::SinOsc::ar().freq(220)))
    });
    let encoded_synthdef = encode_synth_defs(vec![sine_wave]);
    server.send_sync(server::SynthDefRecv::new(&encoded_synthdef))?;

server.send(server::SynthNew::new("sine_wave", 1))?;
    sleep(Duration::from_secs(1));

server.reset()?;

Ok(())
}
```

## Setup

With [cargo-edit](https://github.com/killercup/cargo-edit) installed run:

```
$ cargo add sorceress
```

You must [install SuperCollider](https://supercollider.github.io/download) separately from the `sorceress` crate.

**Note:** Sorceress does not run SuperCollider for you at this time, so you must boot a server yourself. The recommended way to do this by starting the server in **scide**, SuperCollider's built in IDE.
