Get started 🎶

Installation

Run npm install soundy-js

Usage with React Provider

Container:

import { SoundyProvider } from  "soundy-js";

function  Container() {
const  playerRef  =  useRef(null);

return (
	<div>
		<audio
			id="audioPlayer"
			src="your_audio.mp3"
			ref={playerRef}>
		</audio>
		<SoundyProvider  playerRef={playerRef}>
			<YourVisualization/>
		</SoundyProvider>
	</div>
);
}

Visualizer:

import  useSoundy  from  'soundy-js';

const  YourVisualization = () => {
const { 
  getLowFrequencyData, 
  getMidFrequencyData, 
  getHighFrequencyData
} =  useSoundy();
return (
  <div>
  ... your visualization elements here	
  </div>
);
};

Usage with React Hook

Visualizer:

import useAudioFeatures from 'soundy-js';

const  YourVisualization = () => {
const playerRef = useRef(null);
const { getLowFrequencyData, getMidFrequencyData, getHighFrequencyData } =
  useAudioFeatures(playerRef);
return (
  <div>
  	<audio
  		id="audioPlayer"
  		src="your_audio.mp3"
  		ref={playerRef}>
  	</audio>
  	... your visualization elements here	
  </div>
);
};

Currently supported feature set ✅

• Access Low, Mid or High frequency data of your audio

• Retrieve Avarage of Low or Mid frequencies

• Get the peak or the bottom of Low, Mid or High frequencies

• Use the significant beat of the audio as a signal

• Select a custom range of frequency data of your audio

Motivation 🤔

We incredibly enjoy making audio visualizers using javascript only. This projects goal is to provide a library that can make this more approachable for others, by supplying the data from the audio via a React hook or Provider. We mostly experimented creating visualizations using Three.js, SVGs and basic HTML elements.
