Spectacular music visualization

Forgive me, I'm not a Flash user, but apparently this uses two third-party technologies built for Flash: Papervision 3D and an open-source library called Tweener.

I don't know how well this will run for most of you.

I viewed it with the horsepower of an Nvidia 9600 graphics chip, and even it stuttered occasionally.

That seems totally doable in AS. Granted you'd need the music split into separate tracks, but an AS auto-lip-sync switch or audio bone wiggle setup for each track would do that. Then these could be duplicated and placed in the 3D space just like this Flash visualization.

I wonder if Audacity could split up a song well enough?

Not sure but I think this also needs access to "frequencies" of the sound? I don't know the science of sound very well but it looks like this is using the various dynamics of the music, like base and treble if you follow.

As far as I know AS can only work with the amplitude or volume of the sound. If the ability to have some kind of "graphic equalizer" were built into AS, some way to access the frequencies of sound this could be done using lua very easily.

I think "effect01" (using the same link above), shows how certain frequencies effected different parts of the animation.

At present the best you could get in AS would be shapes that reacted to amplitude levels but maybe that is all that is happening here. Maybe if you chopped the sound up into certain ranges of amplitude for different parts you could end up with something similar. Most of those music visualizers are in software that has built in access to the frequencies of the music.

I have been tempted to play with this kind of thing in AS... <sigh> not enough hours in the day sad to say.

Well ... nice ... and instantly forgotten.

Not bad as a programming exercise, but of no real use, except if you have a spare wall in your club.

Actually, I was thinking of it in a more practical application. Like... dancing hamsters.
