OxiSynth

OxiSynth is a pure safe Rust SoundFont™ synthesizer, inspired by the widely known FluidSynth.

Primary Use Case

Initially designed for integration with Neothesia, OxiSynth has expanded its utility to other innovative projects, including:

• microwave: A microtonal synthesizer that makes creative use of OxiSynth's per-channel tuning APIs.
• xsynth: A Black MIDI synthesizer leveraging OxiSynth's soundfont parsing crate.

Showcase

This is how OxiSynth sounds like, running in real-time in Neothesia

The chorus and reverb in the recording are also produced by oxisynth-chorus and oxisynth-reverb crates respectively, that don't have any dependency on oxisynth itself and can be used as generic efects outside of this project.

WASM as first class target

OxiSynth was built with WASM in mind from the get go, so here it is running in the browser, with Boomwhacker soundfont prebundled: https://oxisynth.netlify.app

lib.rs:

You create a new synthesizer with [Synth::new()]. Use the settings structure to specify the synthesizer characteristics.

You have to load a SoundFont in order to hear any sound. For that you use the [Synth::add_font()] function.

To send events use: [Synth::send_event()] function.

To write the results to a buffer use [Synth::write()] function.
