Clap detection (or any other loud sound?)

Do you have access to a scope to look at the mic output? If so, what is the range? If not, a spec/datasheet?

@Robin I don't have a scope.

Do you want the uC to detect the clap (sampling the audio all time) or do you want the sleeping uC be woken up by an interrupt triggered by the microphone?

@maze1980 I want the sleeping uC to be triggered by the mic interrupt.
