Can anyone please tell me how I can use an analogue signal from a piezoelectric sensor (placed under the bridge of a stringed instrument) to trigger a comparator when the signal level goes above a limit? Is there some way of converting the audio signal from the piezo sensor to dc for use in the comparator?
I’m sure that there’s a probably fairly simple answer but I can’t figure it out. Help required! Thanks.
