At the end of the DI for a Simple log-scale audio meter, I promised to show how to upgrade it to work better. With these fixes, it now has near-digital performance, with faster response and smoother ...

Given its appearance in one form or another in all but the cheapest audio gear produced in the last 70 years or so, you’d be forgiven for thinking that the ubiquitous VU meter is just one of those ...

Over the summer [ElectroSmash] put the finishing touches on the Arduino Audio Meter, a shield for the Arduino Uno that visualizes various aspects of an incoming audio signal on a set of four 8×8 LED ...

Usuallyyour meter will be bought or adapted for a specific measurement and youwill not have to make special efforts to get it to read what you want.Or your schematic will specify the sensitivity of ...

The circuit shows the peak level of the audio input using MOSFET Op-Amp. Audio level meters are designed to allow the optimum setting of input level for various sound functions. It utilizes a Metal ...
