What you're looking for is called a peak detector, or probably better in your case - an envelope detector. Pass this through an op-amp with adjustable gain to let you tune your sensitivity. R3 - your potentiometer will let you adjust the sensitivity.Your gain will be . Set Vdd to 5V and common ground with your Arduino.

Programmatically detect and extract an audio envelope. Ask Question Asked 10 years, 11 months ago. ... like to run an algorithm on the series of samples to detect when an event happens i.e. the beginning and the end of an envelope. I would then use this starting and end point to extract that data to be used elsewhere. ... But some pseudo-code ...

The envelope of a signal can be computed using the absolute value of the corresponding analytic signal.Scipy implements the function scipy.signal.hilbert to compute the analytic signal.. From its documentation: We create a chirp of which the frequency increases from 20 Hz to 100 Hz and apply an amplitude modulation.
