A zip file with the official EBU R logo in various graphical format. Note however that no audio blocks are discarded until the final integrated loudness measurement has been done as the final relative gate level will only be known at that point in time.
I like compressed sounds. Due to the massive interest in this topic, group participation in principle is limited to broadcasters and equipment manufacturers. Tech Review – Loudness – don’t forget the distribution chain! Yes, as much as you like, but it won’t make you sound much louder. Other questions If you have any further questions on EBU R or related topics, which are not listed above, or if you intend to implement EBU R Loudness normalisation in your distribution chain, then please send us an e-mail via: As if this wasn’t confusing enough, the frequency dependency of loudness perception itself varies with sound pressure level.
Loudness normalization with EBU R So what are the practical implications of all this stuff for audio production?
EBU Technology & Innovation – Practical guidelines for EBU R (Loudness)
And if yes, what radio platforms could benefit from it? But only comparing the target levels 334 not the full story, as the specs also differ in the tolerances and the maximum True Peak Levels which are allowed.
EBU Recommendation is a milestone in the history of audio broadcasting. This recommendation marks one of the most fundamental changes in the history of audio in broadcasting and solves ehu major source of irritation for television and radio audience around the world: Figure from Wikipedia with edits.
If you have any further questions on EBU R or related topics, which are not listed above, or if you intend to implement EBU R Loudness normalisation in your distribution chain, then please send us an e-mail via: These quasi peaks are then normalized to -9 dBFS see p.
It can be used to determine whether a production requires dynamic treatment and 334 to adapt it to different distribution channels. In short, loudness cannot be easily measured. Can I still use dynamic compression?
And there is more, including Cross-Platform Authentication and a look at the state of loudness normalisation in Europe. EBU tech-i – My media, any device! One could argue the EBU spec allows for a more predictable approach, as it has a smaller tolerance window.

Many vendors support ‘EBU Mode’ in their products. The document presents practical guidelines to relevant settings and processing in the signal chain from the studio to consumer equipment.
The program loudness in LUFS specifies how loud a program is on average from its beginning to its end. See also Too many loudness standards.
My media, any device! In order to prevent clippingthe standard suggests a maximum true peak level of -1 dBFS for PCM, or lower levels eb certain parts of the transmission chain e.
Loudness inconsistencies due to peak normalization. So you can use dynamic compression, but not misuse it to gain loudness. This article describes one of the most fundamental changes in the history of audio in broadcasting: Loudness perception does not directly correspond to signal level. Florian Camerer from the European Broadcasting Union argues that, ” there’s never gonna be such a thing as a perfect loudness meter. Auphonic Help Read more about our solutions: During IBCthere will be plenty of Does EBU R also apply to radio?
