Decibel (unloaded) (dBu) | RecordingBlogs
https://www.recordingblogs.com/wiki/decibel-unloaded-dbu
An unloaded decibel (dBu) is a unit of measurement of the ratio of an amount of voltage V to V 0 = 0.7746 volts given by the formula 20 log 10 (V/ V 0) = 20 log 10 (V/ 0.7746), where voltage is measured using quadratic mean (also called root mean square, RMS).. For example, the professional audio and studio recording level of +4 dBu means. 4 = 20 log 10 (V/ 0.7746)

Audio levels, dBu, dBV, and the gang: What you need to know. April 18, 2017 by Michael Dunn Comments 6. My current audio projects have me thinking about interface levels and decibels, and I know a lot of you out there are uncertain about them. Here’s what you …
Alignment level - Wikipedia
https://en.wikipedia.org/wiki/Alignment_level
Example. For example, alignment level is commonly 0 dBu (Equal to 0.775 Volts RMS) in broadcast chains and in professional audio what is commonly known as 0 VU, which is +4 dBu (equal to 1.227 Volts RMS) in places where the signal exists as analogue voltage. Under normal situations, the "0VU" reference allowed for a headroom of 18 dB or more above the reference …

The home recording level (consumer audio) of −10 dBV means 0.3162 volts, that is −7.78 dBu. The studio recording level (pro audio) of +4 dBu means a voltage of 1.228 volts. The maximum undistorted level of audio amplifiers is +18 dBu. In USA it is +24 dBu. Domestic gear with a −10 dBV level is usually unbalanced.
What is the difference between dBFS, VU and dBU in Audio ...

All analog audio loudness level should be described in terms of dBU or VU measurements. All digital audio loudness level should be described in terms of dBFS. 2.) When recording analog signals, monitoring for clipping is usually observed in the software. To allow more headroom in digital, maximum peak amplitude is -6dBFS.
Audio system measurements - Wikipedia
https://en.wikipedia.org/wiki/Audio_system_measurements
Audio system measurements are a means of quantifying system performance. These measurements are made for several purposes. Designers take measurements so that they can specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative defects of an audio …
dBFS - Wikipedia
https://en.wikipedia.org/wiki/DBFS
Decibels relative to full scale (dBFS or dB FS) is a unit of measurement for amplitude levels in digital systems, such as pulse-code modulation (PCM), which have a defined maximum peak level. The unit is similar to the units dBov and decibels relative to overload (dBO).. The level of 0 dBFS is assigned to the maximum possible digital level. For example, a signal that reaches 50% …
