pulse.js's Introduction

Pulse.js

This library aims to get the BPM (beat per minute) automatically with Web Audio API.

Installation

To install Pulse.js with bower: bower install pulsejs

Usage

Here is a basic usage of Pulse:

var uri = "song.mp3";
var pulse = new Pulse({
  
    // when Pulse has finished to compute main data: beat, significant peaks...
    onComplete: function(event, pulse) {
        var extrapolatedPeaks = pulse.getExtrapolatedPeaks(
            pulse.renderedBuffer,
            pulse.significantPeaks,
            pulse.beat
        );

        // beat (ms and bpm properties)
        console.log(pulse.beat);

        // extrapolated peaks
        console.log(extrapolatedPeaks);
    }
});

pulse.loadBufferFromURI(uri);
