visuals (objects)responding to sound

[quest02 webforumsuser@macromedia.com]

Hi ,
I am working on a new art project ,
is someone there who can give me some basic hints on to make "castmembers " respond to sound
in a way that they move or alter in shape .
in corespondence with the pitch or different tunes
I assume there is a bit of lingo to learn about it
I am verry happy if someone can help me to make a start
..

You will need an Xtra to obtain the sound information

One free Xtra is the FFTXtra it can extract sprctrum content info of
real time sound input, here ar a couple of related links:

There are commercial Xtras that either read the amplitude of a live
signal at the audio input or the level of a playing sound member.

Amplitude Xtra is one, there are at least some functions that work for
free.

You need to set the record source (in Windows) to be something like the CD
player and then play a CD so that the xtra has something to get data from. How
to set the rec-in device depends on your sound "card" driver.
The RealOne viru^Wtroja^Wwor^W player will prevent asFFT from getting the sound.
