ZSynth is a light-weight digital synthesizer audio plugin written in [Zig](https://github.com/ziglang/zig).

It uses

Zig-friendly [CLAP](https://github.com/free-audio/clap) [bindings](https://git.sr.ht/~interpunct/clap-zig-bindings), and

leverages ImGui to render the plugin GUI.

## Features

- Very lightweight CPU load

- 2 oscillators powered by anti-aliased wave tables: Sine, Saw, Triangle, Square

- Intuitive GUI with accurate visual of waveform

- Biquad filter with low pass, high pass, and band pass

- ADSR with flexibility within a time domain of 0ms to 20s

- Optional compile-time embedding of wave tables with `-Dgenerate_wavetables_comptime`

- No oversampling.

## Planned Work

This is just a hobby project / proof of concept for now, but I have some grand designs regardless:

- Custom wave table integration

- On-board delay and reverb

## Installation

### Prerequisites

- ZSynth requires Zig nightly. It was last tested with version `0.14.0-dev.2546+0ff0bdb4a`

- Git

### Steps

1. Clone the repository with `git clone https://github.com/jrachele/zsynth.git`

2. Run `zig build -Doptimize=ReleaseFast` to generate the CLAP plugin. It will be in the `zig-out/lib` folder.

    - Optionally, if you want to embed the wave tables into the binary directly at compile time, run

      `zig build -Doptimize=ReleaseFast -Dgenerate_wavetables_comptime=true` instead.

3. The build process should move the resulting `ZSynth.clap` plugin to your DAW's CLAP plugin folder.
