modal-synthesis

This packages uses the Web Audio API to create a synthesizer for a modal sound.

You can use it to synthesize your own modal sounds, but I don't have documentation for how to do that yet, sorry :(

It involves looking at a spectrogram and identifiying the most important features of the sound.

Eventually I want to make a tool to automate it. But I'm no DSP expert, so it will take me a while.

If you know what you're doing, you can probably figure out how to make your own data, but in the meantime, you can use some samples I included.

Usage

const { makeModalSynthesis } = require("modal-synthesis");
const { glassHit } = require("modal-synthesis/samples");
 
const audioContext = new AudioContext();
 
const glass = makeModalSynthesis(glassHit, audioContext).makeModel({
  // You can use Math.random in here to vary the sound a bit
  amplitudeMultiplier: () => 1,
  frequencyMultiplier: () => 1,
  decayMultiplier: () => 1,
});
 
glass.outputNode.connect(audioContext.destination);
 
// Hit the glass
glass.excite();
