A volume unit (VU) meter or standard volume indicator (SVI) as it’s sometimes called, is a device which displays the audio signal level of an audio signal. It is essentially a basic voltmeter (fitted with transducers to convert sound to voltage) that takes a simple average of the signal and displays it with an attack and release time of around […]

The voice unit (VU) meter is a device that displays a representation of the signal level in audio equipment. It is used in some consumer audio equipment for utilitarian purposes such as in recording devices or for aesthetics like playback devices. The original VU meter is a passive electromechanical device, but using a few LEDs […]
