Nice Kojacker, thankyou.

Could you try youself a other audio example?

I asked 4 days ago here for help to get a signal from the microphone. Could you please try to help and look into it?

In my opinon I have a great Idea for a really nice project. But, I'm only a python and Qt beginner. So I guess the skill level for the core element of my application is to hight for me.

I need "only" every 20 to 100ms the sound level (noise) of the microphone. A spectrum would be even better, but I don't need it. Here is a C++ expample how it should also work at the N900: Link
I have all other needed parts or know how to do.

If it is impossible to do something like this in python, could someone please provide me a Library that could do the trick for me?
