A peak detector that restarts (multiple peaks)

As I said I have 5V AC 10kHz, I forget to mention that is modulated signal, It will look like this
[5][5]
I need to detect all peaks to, and in the end I need to connect all that peaks to get a new signal, that will in the end be the envelope of this signal that I mentioned before. My plan is to build a Non-Inverting Op-Amp Level Shifter(change of plans) to get voltage to 0-3,3 V and connect it to stm32 , and do all programming where my output will be as mentioned the envelope. I am a bit skeptic about all of that, cause I already have bought all material.

Your asking, what analog circuit can form single ended (positive quadrant) signal representing envelope of AM modulated signal with carrier of 10kHz ?
This is AM detector.
