A decent computer and lots of volume is recommended.
Well, due to the fear of slipping behind, I felt I better start learning the new Flash language, Actionscript 3, and at first glance, one of the coolest features is definitely the SoundMixer.computeSpectrum function.
This is a quick experiment which uses the spectrum data of a streaming mp3 to trigger animation. Although it dynamically reacts to the beat, there are elements of randomness in this example so the animation / visualisation is different every time.
I’ve seen a few Actionscript 3 visualisations before, though they tend to follow the graphic equaliser tradition, whereas I wanted something a little more creative.
I will release some source code as soon as I have built this into a robust class. I intend to build an easily customisable music visualisation program which can build visualisations from your own graphics with various configurable parameters.Download: AS3 Audio Visualiser
Have fun, but epileptics beware!
