SBE News for April

For those heading to the NAB Show, we hope you will include the SBE Spring Membership Meeting and SBE Member Reception on Tuesday, April 9 at 5 and 6 pm respectively. Both will be at the Las Vegas Convention Center. Note that the room location for the Membership meeting has been changed to N256 at the LVCC (previously announced for N234/N236).

If you have a NAB Show conference registration, you will want to take in the Ennes Workshop on Saturday, April 6 from 9 and to 12 pm. Separate from the NAB Show, the SBE will be presenting a full-day tutorial on ATSC 3.0 at the Flamingo Hotel, also on Saturday from 9 am to 5 pm. This is being done in conjunction with PBS TechCon but anyone can attend. Registration is $95 for SBE members and employees of PBS member stations. Non-member rate is $145. Register deadline is/was April 1. Register at www.sbe.org.

The SBE Compensation Survey begins commence April 1. SBE members will receive an email with a link to the survey. This is the fourth annual survey conducted by SBE, which tracks salary and benefits for radio and TV engineers. Results will be available in early July and are free to SBE members. We typically have had more than 500 participants in the survey and we encourage everyone to complete it to ensure an accurate measurement.

Membership renewals are due April 1. Renew on line at sbe.org or through the mail, using the renewal letter sent to you in early February. Members can still use the on-line renewal system after April 1.


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.


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.
