An analog VU (volume unit) meter is a splendid moving-coil measuring instrument. It is a passive electromechanical device displaying a representation of the signal level in an audio equipment. Even ...

Retro audio level indicator with analog driver circuit. The goal of this project is to create analog driver circuit for analog VU meter gauges. This device works with standard line level audio signals ...

The circuit was designed based on the functionality of LM3915 integrated circuit to produce a volume unit meter (VU Meter) that will be connected to the output of power amplifier. Power Amplifier – a ...

Abstract: This paper deals with a construction and practical testing of a VU meter driver that includes an accurate rectifier and logarithmic driver of a pointer-type gauge. The logarithm is taken ...

A simple audio visualizer that maps the audio signals from ADC to LED strip. The number of lit LEDs is based on the amplitude of the audio signal, with a brighter peak indicator on the highest ...
