ZSynth

ZSynth is a light-weight digital synthesizer audio plugin written in Zig. It uses Zig-friendly CLAP bindings, and leverages ImGui to render the plugin GUI.

Features

• Very lightweight CPU load
• 4 (Mostly) Anti-aliased oscillators: Sine, Saw, Triangle, Square
• ADSR with flexibility within a time domain of 0ms to 20s
• Optional compile-time embedding of wave tables, virtually no CPU overhead incurred.
• No oversampling or trigonometric functions during runtime.

Planned Work

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

• Perfectly anti-aliased oscillators
• GUI
• Multiple oscillator support
• Custom wave table integration
• On-board filtering and EQ
• 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 and any submodules with git clone --recurse-submodules 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. Move the resulting ZSynth.clap plugin to your DAW's CLAP plugin folder. You may need to rename the file extension from .dll or .so to .clap
