Hello, I would like to create multiple waveforms.

Could someone tell me on why my code is not working?
Thanks.

let p1 = new waveForm()
p1.init('track1.mp3', '#waveform1','play1')

let p2 = new waveForm()
p2.init('track2.mp3', '#waveform2','play2')

Hi @Raspberry42

I did try your example in CodeSandbox - https://codesandbox.io/s/goofy-chandrasekhar-rrhqt?file=/src/index.js

Everything is working good there. Could it be problem with your audio files? Do you have any errors in console?

Thanks
