An analog VU meter with peak LED. A volume unit (VU) meter or standard volume indicator (SVI) is a device displaying a representation of the signal level in audio equipment.. The original design was proposed in the 1940 IRE paper, A New Standard Volume Indicator and Reference Level, written by experts from CBS, NBC, and Bell Telephone Laboratories. [1]
The analog VU meters are actually closer to the human ear's perception of sound level because the response time was intentionally slow - around 300 milliseconds, [2] and thus, many audio engineers and sound professionals prefer to use older analog style metering [citation needed] because it more accurately relates to what a human listener will ...
In analogue systems, alignment level in broadcast chains is commonly 0 dBu (0.775 volts RMS) and in professional audio is commonly 0 VU (4 dBu, 1.228 volts RMS). Under normal situations, the 0 VU reference allows for a headroom of 18 dB or more above the reference level without significant distortion.
These were Type II PPMs with the seven marks labelled −22, −16, −12, −8, −4, 0 and +4. ABC found that a modified version of the EBU meter based on the VU-meter 'A scale' was best, since it let operators use their usual jargon such as 'zero level' etc. [19] The appearance is similar to an EBU scale except that the numbers are 8 dB lower.
Inexpensive analog meters may have only a single resistance scale, seriously restricting the range of precise measurements. Typically, an analog meter will have a panel adjustment to set the zero-ohms calibration of the meter, to compensate for the varying voltage of the meter battery, and the resistance of the meter's test leads.
Loudness monitoring of programme levels is needed in radio and television broadcasting, as well as in audio post production.Traditional methods of measuring signal levels, such as the peak programme meter and VU meter, do not give the subjectively valid measure of loudness that many would argue is needed to optimise the listening experience when changing channels or swapping disks.
A goniometer is often included in analog audio equipment to display a Lissajous figure which shows the amount of stereo (that is, phase differences) in a dual-channel signal. [1] It allows the sound technician to adjust for optimal stereo and determine the makeup of errors such as an inverted signal.
UK broadcasters, alignment level is taken as 0 dBu (PPM 4 or −4 VU) The American SMPTE standard defines −20 dBFS as the alignment level. European and UK calibration for Post & Film [clarification needed] is −18 dBFS = 0 VU. US installations use +24 dBu for 0 dBFS. American and Australian Post: −20 dBFS = 0 VU = +4 dBu.
