#AUDIO VISUALIZER PROGRAM HTML5 CODE#
I'd also like to add that when I take away the "webkit" part of the code located on lines 22 and 35 (for chrome browser), the song no longer works. I can get the song to play but not the bars to show or animate. What I'm basically trying to accomplish is for now, to play one song (.and later a playlist with categories to select the genre of playlist) from a song file with bars moving with the bpm (beats per minute) of the song, underneath the audio player. I tried to follow a youtube video on a tutorial for an audio visualizer ( ), however the support for issues that I'm having aren't very helpful.
