Here is a list of changes between EBU Tech 3343 v3.0 and v2.0 (August 2011):

  • Explanation of basic R 128, its parameters and ITU-R BS.1770 to appendices;
  • Updated recommendations to the actual version of R 128 (tolerances etc.);
  • Vastly expanded section on genre-specific issues (films, commercials, music);
  • New recommendation for acoustical alignment, simplifying the process: a reference signal of 2-octave pink noise (500 Hz – 2 kHz) with a level of −23 LUFS is sent to each loudspeaker and the speaker gain is adjusted to achieve 73 dBC;
  • Clarification of the role of the parameter Loudness Range (LRA);
  • Introducing Loudness Offset – Lower Loudness Flag;
  • Expanded chapter on Downmix and Upmix issues.
