top audio music analyzer visualization 2014

11-So far we’ve only talked about audio synthesis and processing, but that is only half of the functionality that the Web Audio API provides. The other half, audio analysis, is all about understanding what the sound that is being played is like. The canonical example of this feature is visualization, but there are many other applications far outside the scope of this book, including pitch detection, rhythm detection, and speech recognition.
This is an important topic for us as game developers and interactive application builders for a couple of reasons. Firstly, a good visual analyzer can act as a sort of debugging tool (obviously in addition to your ears and a good metering setup) for tweaking sounds to be just right. Secondly, visualization is critical for any games and applications related to music, from games like Guitar Hero to software like GarageBand-.d
