LED VU Level in 20cents

VU meters were originally designed for the analog world to visualize the average volume of a signal. That’s right, a VU meter displays the average volume or loudness of the signal that’s sent through it.

VU meter shows the average loudness of a signal. It shows the energy and intensity of the music. In mixing, a VU meter shows the actual level of the mix.
One of the purposes of a VU meter is this: it’s healthy to have some kind of “borders” when mixing music. The 0VU can be thought of as the border. But it’s not an absolute limit. It’s fine to go a little bit beyond 0VU, as it doesn’t “hurt” the mix in any way. Go too much, and your mix could suffer. Generally, 2-3VU could be considered as the very limits.

Step 1: Introduction

LED vu meters use IC and power supply .

At times the easy vu meters are desired that u can hook to speaker wires .

This is a tested design . the post has circuit and a video for ur satisfaction !

Step 2: The Bare Min Circuit

The ladder based LED dropper is calibrated for 8v At peak power ...

a resistor can be used to limit in current with value 22E

Hope all will like it

Step 3: VDO Demo

Here is a demo video , u can improve it

use joule thief etc
