In a loudness meter implementing EBU Mode: Reference level = −23 LUFS = 0 LU A programme with an integrated loudness of −26 LUFS measures −3 LU in EBU Mode (i.e. is 3 LU quieter than the target level). LRA Loudness Range [8] A statistically determined value that describes the loudness variation (dynamics) of a programme.
Loudness units relative to full scale (LUFS) is a synonym for LKFS that was introduced in EBU R 128. [ 10 ] The EBU has suggested that the ITU should change the unit to LUFS, as LKFS does not comply with scientific naming conventions and is not in line with the standard set out in ISO 80000-8.
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.
Is it correct that the integrated LUFS is based on the momentary loudness rather than individual samples? BTW, I've have already implemented an option to select a source (either individual samples, momentary, or even short-term) to use for the integrated LUFS calculation on the loudness (LUFS) meter part of my own peakmeter so this can be tested.

This convention is the basis for the ITU's LUFS loudness unit, [23] and is also used in Sound Forge [10] and Euphonix meters, [24] and Analog Devices digital microphone specs [25] (though referred to as "dBFS").
Black & Lane's Ident Tones for Surround (BLITS) is a way of keeping track of channels in a mixed surround-sound, stereo, and mono world. [1] It was developed by Martin Black and Keith Lane of Sky TV London in 2004.
When using VU meters, a certain point (usually −14 dB below the disc's maximum amplitude) was used in the same way as the saturation point (signified as 0 dB) of analog recording, with several dB of the CD's recording level reserved for amplitude exceeding the saturation point (often referred to as the red zone, signified by a red bar in the ...
