AN014 - Peak Detection Circuits
https://sound-au.com/appnotes/an014.htm
If the peak detection is to function on both positive and negative half cycles (and they can be very different), a precision rectifier is used in front of the peak detector. This is usually necessary when the signal is asymmetrical, something which is very common with audio signals. The circuits shown here all work on the positive peak only.

Rectifier circuit gives average value of input signal; but in practice we need peak value of input signal. This is achieved by peak detector circuit. The following figure shows a simple peak detector circuit using diode and capacitor. In the positive half cycle, diode D is forward biased and capacitor C starts charging.
How to Build a Peak Detector Circuit
http://www.learningaboutelectronics.com/Articles/Peak-detector-circuit.php
The peak detector circuit we will build with a diode and capacitor is shown below. The breadboard circuit of the circuit above is shown below. So we have a very basic circuit. We have a diode connected in series to a diode which is in parallel to an open circuit. The positive power source is connected to the anode (positive terminal) of the ...

https://www.circuitstoday.com/peak-detector-circuit
Description. This is the circuit diagram of a very simple and cheap peak detector circuit. This circuit operates from 5V DC and can detect signals up to 150 KHz. Dual comparator IC LM393 is the heart of this circuit. First comparator IC1a is used for detecting the peak of the input signal. Second comparator IC1b is wired as a buffer to increase ...
AN012 - Peak, RMS and averaging circuits
https://sound-au.com/appnotes/an012.htm
Peak detection - usually non-precision - is far more common with audio processing systems. If you use peak detection as described here for conventional metering (RMS calibrated), the 'RMS' reading is only accurate when the input is a sinewave. …

Figure 2. Improved Peak Detector. The LTC6244 is a dual high speed, unity-gain stable CMOS op amp that features a 50MHz gain bandwidth, 40V/μs slew rate, 1pA of input bias current, low input capacitance and rail-to-rail output swing. The 0.1Hz to 10Hz noise is just 1.5μV P-P and 1kHz noise is guaranteed to be less than 12nV/√ Hz.This excellent AC and noise performance is …

Note that with this circuit, the peak detector output will always be centred on 2.5V. If you use a 4th opamp to buffer the 2.5V reference point then you can connect all the points requiring to be biased at mid rail to the output of that opamp because it looks like a low impedance voltage source.

flat5. Joined Nov 13, 2008. 403. Apr 3, 2009. #2. To make sure you notice the peak, use a comparator and detector to charge a capacitor to hold the LED on for a second or so. To keep the audio clean branch off from the audio chain without loading the circuit and do this other process off the main track, so to speak. B. Thread Starter.
