Default Soundanalyzer

Hi!

I am trying to work on an app which has a function which records the sound which comes in the microphone. I already coded the record part, which is done by a thread. It would be handy to give a graphical view of the incoming sound, like http://web.hcpss.org/~paul_wiedorn/types/soundengineeringjf_files/soundPicture.jpg or http://image.made-in-china.com/2f0j00UvBEaqIRHdbK/EL-Sound-Activated-T-Shirt.jpg for example.

I searched a little bit for a tutorial online, but the only thing I found was Audalyzer, but it is difficult for me to get a grip on it, it also is using the whole interface and not clear how to implement it as a widget... I am stuck on this.

Maybe somebody knows a good tutorial or example code on this or could help me by coding the basics or something?

Hope somebody wants to become my hero!

You just want something cosmetic? Likely you want to run an FFT on your incoming data, then output a graph of freq vs amplitude.
