OLED display VU meter — AVR/Arduino project. This project is to create digital version of a nice gadget that adds a little magic to any audio equipment: a VU meter. Main design goals are: 2-channel operation, as close to real VU-meter specification as possible, high FPS, 60+ — no visible jumping of needle, as is common in other designs.
vu-Meter for multichannel AVR - Audio - Arduino Forum
https://forum.arduino.cc/t/vu-meter-for-multichannel-avr/614904
Hey there, I am looking for a way to built a vu-meter for my home cinemar receiver. Most designs I found so far use the headphone (or preout) of their amplifiers to measure voltage. But in my case thats impossible since my AVR (Denon AVR-X2300w) only has preouts for L, R and sub. But I want to visualize the surround channels too. Putting a mic in front of every speaker …

The LM3915 is for audio power meters and the LM3916 for VU meters. If you want to use the AVR chip and discrete LEDs then there are ultra bright LEDs available which are quite visible at a few hundred microamps. For battery driven equipment I use them as indicator lights. http://www.candlepowerforums.com...

The LED flashes at about 100Hz for as little noise as possible but can programmatically increase this frequency to 20kHz, but when you disconnect from the sound source, you hear a gentle whistling in the amplified sound.

VU meter with AVR - SparkFun Electronics
https://forum.sparkfun.com/viewtopic.php?t=10952
I decided to break down and ask for some help I've been googling for the past week trying to find some sample code for a VU meter using the ADC on an AVR. I've found several schematics where people have used ICs such as the LM3915 with LEDs but I'd like to display the meter on an LCD instead.

as close to real VU-meter specification as possible, high FPS, 60+ — no visible jumping of needle, as is common in other designs. Project uses AVR ATMega88/168/328 (and ATMega48 if possible), so should be compatibile with Arduino Uno boards. Small (and cheap) monochrome OLED modules with SSD1306 or SH1106 driver are employed as displays.
