Flash Audio Visualization?
January 13, 2009 7:59 AM Subscribe
I'm looking for Flash Audio (music) visualization info... and a bit o' help.
I'm a grad student in multimedia and not a Flash expert. I need to talk (or consult) with someone about Audio visualization (kind of like iTunes visualizer.) This is AS3 and beyond what the flash folks at school know.
I'm just not sure where to find someone to have a conversation with. I'm in the greater SF Bay Area and would even toss a few $ in to get my questions answered. Where to look?

I have LOTS, but my most basic (and the deal breaker for my project) is:
All the examples I've seen use sound files. Is it possible to have it work live using an audio input?

cccorlew, the normal way you detect audio levels -- e.g. with an playing mp3 file -- is via a method of the SoundChannel object called computeSpectrum(). Unfortunately, this won't work with live mic input.
However, there is a method of the flash.media.Microphone class (the hook into the system mic) called activityLevel(). It will return a number between 0 and 100, based on how much volume the mic is picking up. You could use that to drive a visualizer.

But no way to get into the frequency spectrum stuff, eh?

I don't think so. You could get this answered more definitively at one of the many Flash boards, e.g Flashkit.com
