Getting Started

<audio id="audio-element"
  src="path/to/your/song.mp3"
  autoPlay
>
</audio>
<AudioSpectrum
  id="audio-canvas"
  height={200}
  width={300}
  audioId={'audio-element'}
  capColor={'red'}
  capHeight={2}
  meterWidth={2}
  meterCount={512}
  meterColor={[
    {stop: 0, color: '#f00'},
    {stop: 0.5, color: '#0CD7FD'},
    {stop: 1, color: 'red'}
  ]}
  gap={4}
/>

you can also pass audio element to the component

this.audioEle = new Audio('path/to/your/song.mp3) 
<AudioSpectrum
  id="audio-canvas"
  height={200}
  width={300}
  audioEle={this.audioEle}
/>

if you use both audioId and audioEle props, the component will ignore audioEle.
