Yes, a new hope. While some of the recently established metering systems did not successfully managed the loudness race problems in general there seems to be a new hope concerning those issues and this comes from the broadcasters standardization efforts. Started in 2006 the ITU recommendation BS.1770‐1 defined already some replacement for the common QPPM metering and instead was oriented towards loudness metering.
“Briefly, ITU-‐R BS.1770-1 provides a simple and practical solution for the task of finding an objective measurement of what is essentially a subjective impression (loudness). Such a measure can naturally never be perfect, as the perception of loudness depends on many parameters, such as preference, age, mood, frequency, replay level etc. Nevertheless, BS.1770 proved to be a robust standard with the added value of simple implementation.” 
Afterwards, this was the basis for the EBU working group named “P/LOUD” which is going to extend the 1770-1 to the forthcoming EBU recommendation R128 ‘Loudness normalisation and permitted maximum level of audio signals’. The outcome will be basically a set of some newly defined norms heading towards
- Programme Loudness,
- Loudness Range and
- True Peak Level.
Most important, a new target level is defined on top of the metering standardization concerning loudness of program material. Funnily, the magic number is (minus) 23. The standard is open, there are no scary fees on using logos or suchlike and since the driving forces behind P/Loud are the most important ones coming from public broadcasters and manufactures, the acceptance is most likely at least in the broadcast area. The hope is then that this is going to spread through the entire music production business but we have to wait and see of course.
To me, this seems the most promising approach on solving the underlying loudness war problems until now and I will try to support this wherever I can. I’ve already implemented ITU-‐R BS.1770-1 plus some extensions in my lab here and I’m just awaiting the final R128 spec.
