Is there a JavaScript equivalent to ActionScript's channel.leftPeak or channel.rightPeak. This is used for sound programming such as for a VU meter. I am trying to build a sound application, but I was avoiding using Flash and ActionScript since it is for a website. I was wondering if it was possible to do it in JavaScript. The basic concept is just play a song and be able to see the visualization of it through the spectrum analyzer or VU Meter.
