OPTIMOD 6300 DIGITAL OPERATION
ingly, the CBS Loudness Controller in Orban products, which uses the CBS loudness
metering algorithm as its core loudness reference, produces consistent and naturally
balanced dialog levels regardless of the program material and mixing style. Unlike
the BS.1770 meter, the CBS technology does not unnaturally penalize material hav-
ing a low peak-to-RMS ratio, so it allows mixers and producers to freely use "artistic
21
compression" and other well-established production techniques with the knowl-
edge that such material will be neither too loud nor too quiet when compared to
the surrounding program.

It appears that the group that created R 128 may be biased against this style of
production: "Again, this does NOT mean that within a programme the loudness
level has to be constant, on the contrary! It also does NOT mean that individual
components of a programme (for example, pre-mixes or stem-mixes, a Music & Ef-
fects version or an isolated voice-over track) have all to be at the same loudness
level! Loudness variation is an artistic tool, and the concept of loudness normalisa-
tion according to R 128 actually encourages more dynamic mixing!" EBU TECH 3343,
