What is a stereo VU meter?
What is a stereo VU meter?
A volume unit (VU) meter or standard volume indicator (SVI) is a device displaying a representation of the signal level in audio equipment. Consumer audio equipment often features VU meters, both for utility purposes (e.g. in recording equipment) and for aesthetics (in playback devices).
Is a VU meter analog?
Analog VU (Volume Unit) Meters are for the measurement of sound or noise levels as electrical signals in audio equipment. The VU Meters have become the universal standard level for practically all audio frequency transmission systems.
Why is it called a VU meter?
On audio equipment, sound level meters are sometimes called VU meters. VU stands for volume unit (the other common type of audio meter is the PPM or Peak Programme Meter). A VU meter is essentially a voltmeter calibrated to give a reading of 0VU when fed with a sine wave tone.
What is VU and PPM?
A VU meter displays the average volume level of an audio signal. A PPM displays the peak volume level of an audio signal. As the VU meter displays an average volume of the audio signal, it must “sample” the audio signal over a longer time period than the PPM.
How to make an analog audio VU meter?
Just search for analog VU meter. Pretty much all of them are the 500uA of current type, which is the type that is supported with this electronics. I found the base schematic somewhere on the internet and I tailored it to suit my needs.
What does Vu stand for in audio category?
