Oh, excuse me for forgetting to give more information about the project.
I need to cut-off parasite and useless frequencies so I'm forming banpass filter from 159Hz (HPF) to 3.5kHz (LPF). Also, I want to amplify weak signal which is coming from piezo transducer (acting as contact mic). Piezo dimension 27mm. I want full dynamic range from 0V to 3.3V (0 - 1024 adc units).
The whole thing should work as envelope follower so it will be possible to detect percussion hits sensed by piezo mics.
