This article is intended as a follow-up to the previous article, "Keep Calm and
Carry on Mixing/The Mixers' Guide to Broadcast Loudness" by myself and Greg
King, and discusses what's changed (and perhaps more importantly, what hasn't
changed) since then. If you haven't read that, it's a good primer on the history
of LKFS, BS.1770, and the CALM (Commercial Advertising Loudness Mitigation)
Act. [The article is from the Spring 2018 CAS Quarterly and is available via the
Publications > CAS Quarterly Archives section of our website or directly here:
http://digital.copcomm.com/i/987065-spring-2018/67?] In the interests of it
not being an absolute requirement however, I will give a pretty detailed recap, and
also work in some recent developments and information outside the scope of the
CALM Act in the US, namely how loudness is approached in the EU, and get into
how LRA factors in.
