Generate peak audio data from a local filepath or remote file URL in a Node.js environment - without the browser.

Try this out on stackblitz - (run the command node index.js in the terminal)

Use your favorite package manager / npm to install.

npm install node-audio-peaks --save

Version 3.0.1 Is an ES6 module, and uses RxJS to return the audio peak data as an observable.

import { getAudioPeaks } from "node-audio-peaks";

// Generate peaks for a local audio file
let filepath = 'sampleaudio.mp3';
let audioPeaksFromFile$ = getAudioPeaks(filepath);
audioPeaksFromFile$.subscribe(console.log);

// Generate peaks for a remote audio file
let audioFileURL = 'https://www.kennethcaple.com/api/mp3/richinlovemutedguitarechoing.mp3';
let audioPeaksFromURL$ = getAudioPeaks(audioFileURL);
audioPeaksFromURL$.subscribe(console.log);
