July 19 Meeting at iHeart: Orban Processing

Bob Orban will teleconference in to discuss analog and digital radio audio processing, including 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. He’ll also touch on loudness management of digital radio 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. Bob will show measurements assessing how effectively conventional radio-style audio processing controls loudness, and will include practical suggestions about loudness management, and will wrap up with a brief discussion of two recent Orban products for radio and streaming.

Members and guests are welcome to our monthly meeting Wednesday, July 19th at 12 noon at iHeart Media, 9660 Granite Ridge Drive in San Diego. Orban will buy pizza for the occasion. Continue reading July 19 Meeting at iHeart: Orban Processing

June Meeting: SSL, IP Audio and Their Console-less Mixer

Says George Horton of SSL:

Audio-over-IP solutions are now in regular use around the world and in a wide range of critical applications. The installed sound market has been relying on IP transport for many years already, and now many broadcasters are implementing facility-wide AoIP technologies. This presentation covers how we are have reached the current technologies and how they are evolving. We will cover the current alphabet soup of acronyms and standards and finish up with a real word example of the technology in use.

For attendees’ interest, there will also be a range of Network IO solutions and the new ‘Console without an actual console’- SSL TCR- Tempest Control rack. A solution for remote flypack productions or fully automated broadcast facilities.

Join us for our regular monthly meeting Wednesday, June 21, at 12 noon at iHeartMedia, 9660 Granite Ridge Drive in San Diego. SSL will pick up the tab for pizza. As always, everyone is invited.

May 17th Meeting: Sencore and Technology to Help Your Station

If you’re old enough, you remember Sencore as the company that in the 1960’s made quality capacitor checkers and vacuum tube testers. During the digital TV transition, they introduced a cool, modular demodulator adopted by the thousands. They’ve taken it to the next level in the past few years. I have a client with a Sencore satellite IRD that has a streaming IP output and great signal diagnostics and logging.

Jay Gedanken, who represents Sencore in the southwestern U.S., visits Chapter 36 this month to discuss some of the technology you might consider for your broadcast plant. If you’re uplinking to satellite, the FCC is requiring you to have a new carrier ID in place, and he’ll talk about that. Sencore has an end-to-end plant data system monitoring solution called “Videobridge” that he plans to discuss, as well as various methods of transporting video.

Join us Wednesday, May 17th, at 12 noon at KGTV, 4600 Air Way, San Diego. Jay will buy us lunch in the cafeteria, then we’ll have an hourlong presentation with Q & A.

About Jay

Jay Gedanken has been with Sencore for the past two years. He started his career as an electronics engineer, but moved into technical sales, where you might know him from his time in San Diego at Adtec, Scopus, CBW Systems, and Optibase.

March Meeting: Jampro Antennas and Design Considerations of TV Spectrum Repacking

Broadcast TV antenna manufacturers should make some good sales numbers in the next couple of years as the FCC forces broadcasters to shuffle channels again. This time around, the emphasis will be on broadband designs. Jampro has been working to make their antennas work on multiple channels with minimal wind loading. Many broadcasters will be looking at designs that make the best use of ATSC 3.0 as well. There are things to keep in mind you as broadcast engineers may not have considered, like OFDM Crest Factor and circular polarization for mobile coverage. Jampro logo

As a bonus, they plan to talk about their experience in Singapore with DVB-T2 and Single Frequency Networks.

Join us March 15 at 12 noon at KGTV, 4600 Air Way near I-805 and CA-94 in San Diego for the Chapter 36 regular monthly meeting. Jampro is buying lunch in the cafeteria.

Come on by, and bring a friend.

 

February 15 Meeting: Audio Precision and the Noise Floor

How Low Can You Go?

What are the capabilities of modern test equipment and its ability to test very low noise and distortion devices? Can test equipment of today keep up with increasingly impressive specs? Are the specs real? We’ll review some real world examples from both the electrical audio test world as well as room acoustics testing.

Join Chapter 36 Wednesday, February 15, at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Audio Precision buys lunch. Members and visitors are welcome as always.
