Help needed for building a GWT Waveform library

[Xybrek]

I'm trying to build a open source GWT audio recorder waveform library, this is the showcase site:

http://recorderwave.appspot.com/Showcase.html

Run Demo Wave:

Works just fine.

Recording:

The waveform rendering out of real time data from the flash interface is not really good, the performance is not really good, and it is really not working properly.
Also, I am not sure if my sampling strategy is correct. And if you look at the Chrome/Firefox console there are many errors although it renders somehow. And most
importantly the recording takes place within 10 seconds but the waveform renders goes beyond that time.

If you are interested with having this library with GWT, maybe you can check out the code:
