Here are the slides from my Flash On The Beach 2008 session “AudioTool’s Private Parts”. 2mb without a prelaoder. You will need Flash Player 10 to pass through to version detection or you can save the SWF directly to disk and watch it with Flash Player 9.

I wrote a while ago about our tween engine at Hobnox but I did not post any performance demos.
Here are the results for 1000 DisplayObjects with manipulation on their scaleX, scaleY, alpha, x, y and rotation properties. It is also very important that you take a look at the memory behaviour. A click starts the tweening.
As you can see it makes a lot of sense to stay type-safe and to manage the memory you are using on your own.
I will talk about those concepts in my next session AudioTool’s Private Parts in Brighton and Boston. Since optimization on a code level is trivial the main performance boost is achieved by re-thinking algorithms, structures and concepts. I guess one of the most interesting topics will be the optimization of our cable solver which was running O(n^2) (really!), then O(n(n+1)/2) and could be minimized to a rare O(n(n-4)/2) worst-case.
Last friday was an awesome day. It was my birthday, Microsoft released Photosynth which is a product I have been watching since two years and we won the FlashForward Award in the category Sound with our Audiotool.
The Audiotool development became a very interesting topic. We implemented so many things to keep stuff optimized not only on the code layer but also on the algorithm layer. I am really looking forward to talk about some techniques in my session “Audiotool’s Private Parts” at Flash on the beach and Flash on tap.
