LM2 / LM6: How to set up for OP-59 compliance

Question

How do I calibrate LM2 / LM6 settings for matching the OP-59 standard?

Answer

The OP-59 standard is rooted in and measured via the algorithm developed by ITU which is referred to as ITU-R BS.1770, the current evolution of which is ITU-R BS.1770-3.  LM2 / LM6 doesn't contain a specific preset with the OP-59 name, but the important settings are:

  • Loudness Standard: BS. 1770-3 
  • Target: -24 LKFS 
  • Loudness Unit: LKFS

These are the same values as the TR-B32 LKFS preset, so selecting that one will get you there, too.
