Typical VU meter. Source: Hoyt Meter The scale to the left of the zero point is generally in black, with a value of -20 dB all the way at the bottom of the scale. Past the 0 dB point, the scale is ...

Thus, a VU meter is a device for measuring the level of sound intensity with audio equipment, such as amplifiers and tape recorders. Although the measurements indicated on such a meter are in decibels ...

VU meters measure the volume (intensity) of analog audio signals. They display signal levels in volume units (VU), a measure of average volume level. By definition, a volume indicator (VI) reading of ...

Although 0 VU is shown on a VU meter as the point of 100% MODULATION, it is not identical to the reference called zero level, which in fact refers to -4 dB or -4 VU on the meter. Zero level is the ...

Last month we featured a project that aimed to recreate the iconic mechanical VU meter with an Arduino and a common OLED display. It was cheap and easy to implement, and promised to bring a little ...
