NEXT MEETING: Thursday, January 25th, 2018 at noon
Our first meeting of 2018 will be on Thursday, January 25th at noon at the
Hubbard Radio studios in Creve Coeur, MO. We look forward to another
teleconference presentation from Bob Orban, who will discuss audio processing for television.
The presentation will cover Orban's approach to automatic, CALM-Act-compliant loudness control as embodied in the
Optimod-TV 8685 Surround Loudness Controller, and will discuss the features of the 8685 in detail.
It will discuss how Orban combines the CBS Technology Center and ITU-R BS.1770 approaches to obtain the advantages of both.
It will cover the concept of "genre" in the context of BS.1770, as first introduced in a 2015 AES Recommendation,
and how taking genre into account can reduce some of the practical objections that have been raised as a result of
experience with normalizing all program material to the same BS.1770 target loudness.
It will present measurements showing the effectiveness of Orban's approach.
We are planning a presentation on LED tower lighting technology and another St. Louis radio/TV
history presentation from Ron Elz, aka Johnny Rabbitt, this winter/spring.
Any meeting suggestions or offers to host a meeting or tour are always welcome. Contact Bob Hoffman or call (314) 983-6222 if you have suggestions.
