ChiptuneSynth is Open Source

March 5, 2026 · Open Source

We're proud to announce that ChiptuneSynth, the synthesis engine at the heart of 8Bit Forge, is now available as a standalone open source library.

What is ChiptuneSynth?

ChiptuneSynth is a browser-based 8-bit synthesizer built on the Web Audio API. It provides 8 independent tracks, 5 waveforms, ADSR envelopes, LFOs, filters, and more — all with zero dependencies.

Getting Started

npm install @8bitforge/chiptune-synth
import ChiptuneSynth from '@8bitforge/chiptune-synth';

const synth = new ChiptuneSynth();
synth.noteOn(0, 'C4');  // Play C4 on track 0
synth.noteOff(0);       // Release

Key Features

  • 8 independent tracks with individual mixer settings
  • 5 waveforms: Square (with PWM), Triangle, Sawtooth, Sine, Noise
  • ADSR envelope per track
  • Unison voices (1-16) with detune and stereo spread
  • 3 LFOs for vibrato, filter modulation, and tremolo
  • Filter with lowpass, highpass, and bandpass modes
  • Built-in FFT analyser for visualizations
  • Master limiter to prevent clipping

Why Open Source?

We believe that core audio tools should be accessible to everyone. By open-sourcing ChiptuneSynth, we hope to enable more developers to integrate authentic chiptune sound into their projects — whether it's games, music apps, or creative experiments.

The library is available on GitHub and npm. Contributions are welcome.
