EBU R 128 is a recommendation for loudness normalisation and maximum level of audio signals. It is primarily followed during audio mixing of television and radio programmes and adopted by broadcasters to measure and control programme loudness. [ 1 ]
The QSA code and QRK code are interrelated and complementary signal reporting codes for use in wireless telegraphy . They replaced the earlier QSJ code. They replaced the earlier QSJ code. Currently, the QSA and QRK codes are officially defined in the ITU Radio Regulations 1990, Appendix 13: Miscellaneous Abbreviations and Signals to Be Used in ...
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.
In 2010, the EBU published EBU R 128 which introduces a new way of metering and normalizing audio. The Recommendation uses ITU-R BS.1770 loudness metering. As of 2016 [update] , several European TV stations have announced their support for the new norm [ 16 ] [ 17 ] and over 20 manufacturers have announced products supporting the new EBU Mode ...

The color names for these different types of sounds are derived from a loose analogy between the spectrum of frequencies of sound wave present in the sound (as shown in the blue diagrams) and the equivalent spectrum of light wave frequencies.
The target loudness is specified as the loudness of a stereo pink noise signal played back at 89 dB sound pressure level or −14 dB relative to full scale. [3] This is based on SMPTE recommendation RP 200:2002, which specifies a similar method for calibrating playback levels in movie theaters using a reference level 6 dB lower (83 dB SPL, − ...
Loudness levels measured according to the Leq(RLB) specified in ITU-R BS.1770 are reported in LKFS units. The ITU-R BS.1770 measurement system was improved for made multi-channel applications (monaural to 5.1 surround sound). To make the loudness metric cross-genre friendly, a relative measurement gate was added. This work was carried out in ...
