This counteracts the tendency to overcompress. Latest tech-i magazine now out 23 Mar The latest edition of tech-i magazine is now out! The metering approach can be used with virtually all material. The loudness range LRA indicates the variation of loudness over the course of a program and is measured in LU.

This recommendation marks one of the most fundamental changes in the history of audio in broadcasting and solves a major source of irritation for television and radio audience around the world: My media, any device! Many national broadcasters have adopted it and over 70 product manufacturers are offering tools in support of EBU R Its specification is about as intuitive as its name, but suffice it to say that the standard describes an efficient and open algorithm for loudness and peak level measurement: Various audio mixers in the PLOUD Group have argued that the normal rules should indeed apply to IS too, as this makes for a simpler workflow and more predictable results.

EBU tech-i 27 – Virtually Ready? And if yes, what radio platforms could benefit from it? One could argue the EBU spec allows for a more predictable approach, as it has a smaller tolerance window. There are no specific rules provided for IS without voice-over!


As if this wasn’t confusing enough, the frequency dependency of loudness perception itself varies with sound pressure level. Loudness perception is surprisingly complicated.

Loudness (PLOUD)

The more you compress, the lower the fader will have to be to reach the same Loudness target level LUFS. A loudness war is taking place from CD mastering to broadcasting.

It tells how broadcasters can measure and normalise audio using Loudness meters instead of Peak Meters PPMs only, as has been common practice. It can be used to determine whether a production requires rbu treatment and how eu adapt it to different distribution channels.

EBU tech-i magazine, Issue 25 tells you all about personalisation, why broadcasters should go IP, and how subtitles go live. How do we produce ‘smarter’? Have you ever wondered why commercials sound louder than your favorite TV shows?

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: And there is more The document describes how to change audio levelling from peak normalisation to loudness normalisation in accordance with EBU R Media production tools in the 33433 17 Apr Maurizio Montagnuolo RAI offers insight on supporting workflows on an advanced cloud media store.

The physical sound pressure level, which is usually specified in dB, tells us very little about how loud a sound will be perceived 33343 a listener.

EBU Technology & Innovation – Loudness (PLOUD)

Input and knowledge of experts For example, an audio signal with a large LRA might need to be compressed, and podcasts generally require a lower LRA than classical music recordings. Get your copy of our latest tech-i magazine today and stay up-to-date with the latest news in broadcasting technology and innovation.


Florian Camerer from the Evu Broadcasting Union argues that, ” there’s never gonna be such a thing as a perfect loudness meter. Loudness inconsistencies due to peak normalization. Where tools have no clear company owner, the tool name is used. Due to the massive interest in this topic, group participation in principle is limited to broadcasters and equipment manufacturers.

It is important for broadcasters to be aware of the loudness paradigm and how to adopt their systems and working practices accordingly. Try Auphonic Try the Auphonic automatic audio post production web service:. But at the same time, peak normalization has been used as a method for maximizing the loudness of an audio program, despite the fact that peaks do in no way determine how loud a signal is perceived.

Auphonic Help Read more about our solutions: Technical Review 24 Sep And that’s not all Try Auphonic for Free. This article presents some solutions for avoiding loudness differences in radio and television broadcasting, based on levelling recommendations and a newly-developed loudness algorithm. We believe dynamic compression is used too much in current practice, reducing the quality of productions.

Find out by reading this article. Over time, it became increasingly obvious that a unified reference was required to normalize different audio programs to the same perceived loudness.

Peak normalization therefore results in unpredictable loudness levels.
