This whitepaper examines how broadcasters can share production resources to increase their content's production, in a quicker and less expensive manner, while operating in a highly competitive environment.
Henry Ford's famous quote, "Customers would have asked for faster horses," applies to broadcasters clinging to old SDI habits. IP technology demands new thinking, prioritizing dynamic orchestration for distributed production.
For broadcasters, the Cloud could offer significant benefits, enabling fixed, capital-intensive cost to be replaced with operational costs aligned with usage, and increasing flexibility within their infrastructure.

The Omnia.11 Broadcast Audio Processor is available in FM+HD with separate processing paths for FM or HD/DRM and FM without HD/DRM. The FM-only model is upgradeable to FM/HD at a later date. Switchable Single Sideband Suppressed Carrier (SSBSC) technology for potential reduction of multipath is a standard feature. A front panel touch screen GUI, on a 10.5" diagonal screen, provides ease of use and enhanced metering and diagnostics. Remote access is available via any web browser. Livewire, AES/EBU digital and analog I/O are standard. Fanless cooling. Rugged 4 RU chassis.
Nominal Input Level: +4dBu, which nets a -18dBFS input meterreading on a steady-state signal when the Input Gain controlis set to 0.0dB. Program material with a nominal average level(VU reading) of +4dBu will typically produce peak readings on the input meter in the range of -12 dBFS to -6dBFS. This is the correct operating level.
The measured noise floor will depend upon the settings of the Input and Output Gain controls and is primarily governed by dynamic range of the Crystal Semiconductor CS5361 A/D Converter which is specified as >110 dB. The dynamic range of the internal digital signal processing chain is >144 dB.
Two: the IP address that you enter into the unit's Network Setup menu, and the next higher address. For example, if you enter 192.168.1.1 in the Network Setup menu, Omnia.11 uses 192.168.1.2 as well. So, make certain that both addresses are available on your network. Use the first address (that you entered) to access the unit for remote control or Livewire. The second address is not directly accessible.
The short answer for the Omnia.11 is "Too much for your DJ's to monitor directly from the FM or HD channel outputs". About 35ms. BUT...The DJ's can use the special low-delay DJ output instead (depending on your system). This can be routed to any of the Omnia.11's outputs in the appropriate submenu of the Output menu.
The AGC system uses true RMS control, which means that each of the individual AGC processors in the Omnia.11 "hears" the audio the way the human ear does. Historically, some processors have used weighted "peak" detectors which, responds to the electrical "peak" value of the audio. This peak value is then smoothed over and used to control the audio levels. This method definitely provides level control, but the "action" of these processors was typically unnatural. This wasn't much of an issue ten to fifteen years ago when CD mastering was much more relaxed.
In today's world, it isn't unusual to have CD's that are just as processed (if not more) than a typical radio station. When an audio processor that used weighted peak control is used on this material, it will add more processing on top of what is already on the CD. This results in a very unpleasant sound on the air, and it is not at all what our ears are expecting from this audio material.
If a processor were designed to "hear" audio the way we do, the reaction would be completely different. To accomplish this task, the level control could not be based on peak electrical levels, but rather on the average power level of the program material.
No. Just because we are not forced to utilize a separate processing structure, this does not mean that the HD transmission is not independently controllable and able to be sculpted for the characteristics of HD transmission.
What was lacking in the traditional approach was that, up until recently, bass management was a very simple process since source material did not contain the intense low end of today's music. All you needed to do back then was to run the bass through a simple clipper and filter out the high frequency harmonics with the low pass filter. To this day, this is how virtually every other processor is designed. Omnia.11 incorporates sophisticated bass management employing many of the techniques that were previously used only to clean up the high end. So both sides of the spectrum now have equally powerful, dedicated management systems.
No. Omnia.11 version 3.0 is FREE, just like previous system updates. v3.0 does enable two new optional Plug-Ins, G-Force and the Perfect Declipper. These Plug-Ins are the culmination of years of R&D and enable you to turbo-charge your Omnia.11 sound. Rather than put them in a face-lifted box and call it a 'new product', we're giving you the options to purchase an entirely new dynamics engine with the G-Force Plug-In and a revolutionary new algorithm with the Perfect Declipper Plug-In, at a fraction of the cost of buying a new processor.
No. As part of our Customer Loyalty program, anyone who purchased an Omnia.11 in 2016 gets the G-Force Engine Plug-In free. It's easy. You'll need to install the latest Omnia.11 software update, version 3.0. Once you do that, you simply have to order and install the G-Force Engine Plug-In. As we've said before, it's like getting an entirely new audio processor with cutting-edge Omnia processing, without buying a new box.
It works the same way: You simply have to download v3.0 software and purchase and install the G-Force Engine Plug-In, which is $985 for any unit purchased before 2016. We want to emphasize that G-Force is not a simple software update. It is a powerful new engine that you can evaluate for free and purchase as an option.
No. While it gets its name from its sister product, "Voltair Mode" does not alter tones, nor is there a "mini Voltair" inside the Omnia 11. What "Voltair Mode" does is place the encoder in precisely the right place in the processing chain for optimal watermark performance. It works quite effectively with, or without a Voltair in the processing chain. Voltair Mode was made possible by G-Force's dynamics architecture. It leverages some of the unique knowledge we acquired as part of Voltair's development, and speaks to the fact that many of our senior engineers play key rolls in both Omnia and Voltair development teams.
The motivation for audio signal processing began at the beginning of the 20th century with inventions like the telephone, phonograph, and radio that allowed for the transmission and storage of audio signals. Audio processing was necessary for early radio broadcasting, as there were many problems with studio-to-transmitter links.[1] The theory of signal processing and its application to audio was largely developed at Bell Labs in the mid 20th century. Claude Shannon and Harry Nyquist's early work on communication theory, sampling theory and pulse-code modulation (PCM) laid the foundations for the field. In 1957, Max Mathews became the first person to synthesize audio from a computer, giving birth to computer music.
Major developments in digital audio coding and audio data compression include differential pulse-code modulation (DPCM) by C. Chapin Cutler at Bell Labs in 1950,[2] linear predictive coding (LPC) by Fumitada Itakura (Nagoya University) and Shuzo Saito (Nippon Telegraph and Telephone) in 1966,[3] adaptive DPCM (ADPCM) by P. Cummiskey, Nikil S. Jayant and James L. Flanagan at Bell Labs in 1973,[4][5] discrete cosine transform (DCT) coding by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974,[6] and modified discrete cosine transform (MDCT) coding by J. P. Princen, A. W. Johnson and A. B. Bradley at the University of Surrey in 1987.[7] LPC is the basis for perceptual coding and is widely used in speech coding,[8] while MDCT coding is widely used in modern audio coding formats such as MP3[9] and Advanced Audio Coding (AAC).[10]
An analog audio signal is a continuous signal represented by an electrical voltage or current that is analogous to the sound waves in the air. Analog signal processing then involves physically altering the continuous signal by changing the voltage or current or charge via electrical circuits.
Historically, before the advent of widespread digital technology, analog was the only method by which to manipulate a signal. Since that time, as computers and software have become more capable and affordable, digital signal processing has become the method of choice. However, in music applications, analog technology is often still desirable as it often produces nonlinear responses that are difficult to replicate with digital filters.
