60 S U M M E R 2 0 2 3 I C A S Q U A R T E R L Y 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:] 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. b y J o n G r e a s l e y C A S M P S E LOUDNESS: THE REVENGE Specs, LKFS, LRA, and Why There's Still No Substitute for a Good Mix (OR: How I Learned to Stop Worrying and Love Dialogue Intelligence)
