There is a section on spectrum analyzers.  
I spoke with steve (the guy who wrote it) and he said that the values are represented as 0 to 1, so 0 would be the lowest frequency.  
That is what I want; to grab the low frequencies ONLY, so how would this be used?

Let’s consider I have a movie on stage called mc\_ball.

Here is the link to his files as can be seen on the bottom of his page:

NOTE:

I had a similar post, but I did the best with that one and got very close, however, it gets clouded when there are a lot of frequencies involved. I ended up just resizing the ball depending on the value read in by byteArray.  
I will still work with it, and may be able to get it to work well, but I would still like to learn how to use things like this guy made. I think he called it a singleton…

It is great that there are actionscript 3 tutorials out there, but this is a different world, and nothing seems to address spectrum analyzation very well.

Thanks
