Our LAST Monthly Meeting

WHEN: Wednesday January 9, 2019, 6:30P Dinner, 7:15P Program Presentation

WHERE: WLWT-TV Conference Room, 1700 Young St, Cincinnati, OH 45202

PROGRAM: Audio Processing for Radio-TV-Streaming Engineers by Bob Orban via Teleconference

The presentation discussed techniques for processing bass (including subharmonic synthesis), the uses and pitfalls of de-clippers,
use of multidimensional phase correction to minimize mono reception while minimizing multipath distortion, and use of parallel compression for pre-processing, loudness management of digital radio, digital television, and streaming using both the BS.1770 and the Jones & Torick (CBS) algorithms, with particular consideration given to the 2015 AES TD1004.1.15-10
“Recommendation for Loudness of Audio Streaming and Network File Playback” publication. Presented were measurements assessing how effectively conventional radio-style audio processing controls loudness, and included practical suggestions about loudness management. A brief discussion of two recent Orban products for radio and streaming and a Q&A session wrapped up the meeting.

Bob Orban should need no introduction, but just in case…..

In 1970, Bob founded Orban Associates, originally as a manufacturer of studio equipment. In 1975, Orban Associates introduced the original Optimod-FM 8000, which was the first in a long line of broadcast audio processors for AM, FM, TV and digital broadcasting from the company. Orban has also been involved in professional recording for many years and has mixed several records released on
the Warner Brothers label, as well as on small independent labels. As a composer, his music has been heard on classical radio stations in New York and San Francisco, and his score for a short film, “Dead Pan,” was heard on PBS television in Chicago. He has designed studio reverberators, stereo synthesizers, compressors, parametric equalizers, enhancers, and de-essers under both the Orban and dbx brand names.

Bob Orban has been actively involved in NRSC committee AM improvement work. He has been widely published in both the trade and revered press (including Audio Engineering Society, Proceedings of the Society of Automotive Engineers, and SMPTE). He co-authored the chapter on “Transmission Audio Processing” in the NAB Engineering Handbook, 10th edition. He currently holds over 20 U.S. patents.
In 1973 he was elected a Fellow of the Audio Engineering Society. In 1993, he shared with Dolby Laboratories a Scientific and Engineering Award from the Academy of Motion Picture Arts and Sciences. In 1995, he received the NAB Radio Engineering Achievement Award. In 2002, he received the Innovator award from Radio Magazine.

Recently, Orban introduced the Optimod PCn 1600, the first Optimod that runs natively on the host computer’s Intel x86 processor; the software does not use dedicated DSP chips.

SBE News for October

The next SBE webinar is October 17 and it’s Module 2 of the SBE ATSC 3.0 series, “Overview of the Physical Layer,” presented by Luke Fay, Sr. Manager, Technical Standards, Sony Electronics.  Register at the SBE website.  It’s free for SBE MemberPlus members.

You may have heard that Richard Strickland recently passed away. Richard presented the SBE RF Safety Webinar for the past ten years. An expert in the field of RF safety, he was well known in the broadcast community. Our sincere condolences are extended to his family. Richard was scheduled to present again for SBE on November 15. Our education team is working to engage a new presenter and will reschedule the webinar for a later date.

How Repack Affects the Operation of Wireless Microphones

A phone call from SBE 33 Vice-Chair Jerry Erwin prompted a little research.  Here’s what the FCC says: Operation of Wireless Microphones.

Here is a link to a YouTube video of a presentation titled, “Building the Advanced RF Transmission System at One World Trade Center” that was made October 27, 2017 as a part of the AES Convention in New York City.
