LED Comparator Display - Audio Volume Level - …
https://www.instructables.com/LED-Comparator-Display-Audio-Volume-Level/
Comparator circuits are very handy when you need a visual representation of an adjusting voltage level. My most common application is a volume indicator on an audio source. The output can be shown through a few LED's and give the user a quick and easy to …
Comparators - sound-au.com
https://sound-au.com/articles/comparators.htm
Comparators are used where the output is either on or off. There is no linear region, and attempting to use a comparator as a linear amplifier will almost always produce an oscillator, where the frequency is determined by stray capacitance, inductance (in …
Audio level detection - (AGC with comparators) | diyAudio
https://www.diyaudio.com/community/threads/audio-level-detection-agc-with-comparators.176858/
I'd like to knock up a circuit which monitors an incoming DC voltage & compares it against a reference voltage - if the incoming DC voltage is too high, then the DC voltage output from this particular circuit slews down, & vice versa. Now, I'm cool with the idea of a comparator - …

https://electronicsarea.com/audio-level-indicator-using-lm339/
Audio level indicator using LM339 This audio level indicator using LM339 circuit is very interesting, since it allows us to visualize the intensity of the audio level by connecting this circuit to the input of a speaker. The LM339 integrated circuit has 4 comparators that operate completely independently, but share the same voltage source.

DIGITAC Comparator Features Assures consistently high quality audio levels from all receivers to the comparator. Status tone output from the comparator allows a group of satellite receivers to feed into a remote comparator and present these signals into …
Op-amp Comparator and the Op-amp Comparator Circuit
https://www.electronics-tutorials.ws/opamp/op-amp-comparator.html
The Op-amp comparator compares one analogue voltage level with another analogue voltage level, or some preset reference voltage, V REF and produces an output signal based on this voltage comparison. In other words, the op-amp voltage comparator compares the magnitudes of two voltage inputs and determines which is the largest of the two.

Comparator. A comparator is a circuit that compares two input voltages or currents and gives output High or Low as per input signal. The Output is a digital form according to the input signal compared with the reference. Basically a comparator is used in electronics to compare the two Analog input signals given on both input terminals and we get the Digital output as High level …

Simple VU Meter Circuit using LM358 - Electronics Projects
https://circuits-diy.com/simple-vu-meter-circuit-using-lm358-electronics-projects/
Working Explanation A simple VU meter consists of a no. of LM358 dual op-amp IC’s, each LM358 contains two comparators inside. These comparators compare the audio voltage signal with a reference voltage. In VU meter, reference voltage at the not-inverting terminal (+) is adjusted by voltage divider circuit.
