Small correction: the formula itself was published by the Pleasurize Music Foundation (https://web.archive.org/web/20131206121248/http://www.dynami... ), not by loudness-war.info (which publishes only the results of the formula on various releases).

There are other tools that can compute it, including MAAT DROffline MkII (proprietary), as well as a couple open-source, Python-based tools (DR14 T.meter, DR Check), or https://github.com/sboukortt/speedr in C++.
