A JavaScript-based audio visualizer that supports frequency (bar) visualization and waveform visualization. It uses the browser-based Web Audio API to obtain frequency data from an audio stream, and uses this data to produce a colorful visual effect. Works in all modern browsers except for IE11.

#Using the audio visualizer in your project Simply add this HTML to your document:

<script src="[path to visualizer].js"></script>
<div id="audio-container">
    <canvas id="audio-display"></canvas>
</div>

Then call the playAudioVisualize function with the path to the audio file to be played as the argument:

<script>
  playAudioVisualize('[path to file].mp3');
</script>
