Sonia vs. Webcam

Thanks to some wise guidance from Amit, finally got the microphone input working well enough to try a few examples. Got side tracked by some older webcam experiments so decided to try merging the two...

It is a bit longwinded and you will get the idea after a couple of seconds. I am using the sound input (in this case, Royksopp played through speakers being picked up by microphone) to control the height of the z-axis for each point of the webcam input (based on the center line horizontally). Picture is worth a 1000 and my description isn't up to snuff.

UPDATE-----------
Oh, and you will notice a lack of sound in this movie.  Did the ol screen grab method and pieced it together so the sound will have to be imagined.
BTW, I poked around on the forum for any information on the subject of browser accessing webcam and didn't find anything. Is this something that will eventually be possible?

Round 2...
Sonia and Webcam vs. White caps.
I recall a sound visualizer plugin (not sure for what app though) that allowed you to see pretty trippy line-based visuals by some guy named Andy something or other. I think he was highly religious and was in training to be a nuclear sub crewmember... i digress
Here is my attempt. Once again, you need to pretend the visuals match with the CD that is playing.

hey robert,
i like the second one the best - the first one was a bit difficult to see what was going on (too high peeks and to fast rotation!) ... in the second one, the fading height of the peeks are a nice effect (along with the white "playhead"-like wobble in the beginning!).
is this running realtime on your computer?

I agree.. the first one is a bit vague. I cant think of a good way to showcase what is actually going on without filming my monitor with a DV cam.
Everything is real-time and I am getting about 12 to 15 fps with both the video and audio processing happening at the same time.
When I add the saveFrame() command, the fps drops to about 1 or 2 per second so the final output movie ends up being really jerky.
Does anyone have any suggestions as to how I can represent this piece properly? I will eventually add it as a project to flight404.com but unless I can sync up the actual audio used to make the project, the overall effect will be lost.

Played around with the new and improved Sonia and finally have a few examples complete with sound. Check the bottom three links at flight404.com.
With constant webcam input, a sound file is analyzed in 30th of a second intervals. The resulting screen grabs are then put together in quicktime pro with the original sound added. Really good for doing effects that are processor intensive as a sound reactive piece.
