True Peak Detection. In the last few years, a number of different countries have passed laws regulating the loudness of audio in television and other broadcast mediums. Surprisingly, loudness is a difficult concept to capture with a simple technical specification. Current regulations set limits for a number of different audio metrics, including ...

Simple Audio Peak Detector. Posted Thursday, April 25, 2013. This audio peak detector allows a pair of stereo channels to be monitored on a single LED. Identical circuitry is used in the left and right channels. Use is made of the switching levels of Schmitt trigger NAND gates inside the familiar 4093 IC.

https://www.dsprelated.com/freebooks/sasp/Peak_Detection_Steps_3.html
Peak Detection (Steps 3 and 4) Due to the sampled nature of spectra obtained using the STFT, each peak (location and height) found by finding the maximum-magnitude frequency bin is only accurate to within half a bin. A bin represents a frequency interval of Hz, where is the FFT size. Zero-padding increases the number of FFT bins per Hz and thus increases the accuracy of the …
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.

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.
