Get audio from an html5 video

Question

Is it possible to get the audio from an mp4 or webm video element in HTML5?

I\'m trying to use https://github.com/corbanbrook/dsp.js to calculate FFTs for audio, however

Answer 1

Not sure if this answers your question but you can run the audio of the video through the Web Audio API node graph. The code below can be demonstrated by changing the gain and filter parameters. I only tested this on Chrome.

The above code is a modified version of this : http://updates.html5rocks.com/2012/02/HTML5-audio-and-the-Web-Audio-API-are-BFFs

I simply replaced the audio element with the video element.
