Introducing Omnia.9/XE
Introducing Omnia.9/XE
Omnia.9/XE is a software-only version of the processing and streaming encoder portions of the “Omnia.9 by Leif Claesson” hardware broadcast processor, including Undo - the revolutionary de-clipper and multiband expander that removes distortion and restores dynamics to music that has been clipped and over-compressed during the mastering process.
Broadcasters have always taken their on-air processing seriously, but too often streaming audio fails to get the same careful consideration. Sometimes the audio destined to the streaming encoder isn’t processed at all (leading to listener complaints about wild swings in audio levels). Sometimes it is processed with a cheap wideband hardware processor rescued from the pile of de-commissioned equipment (resulting in low-quality sound with audible processing artifacts). Now and again, it may even be fed by the same processor as the FM signal path (which results in high levels of distortion and a correspondingly high tune out rate).
Omnia.9/XE is designed for terrestrial or streaming-only broadcasters who understand the importance of providing the highest quality audio possible to their listeners on a wide variety of devices and with varying amounts of available bandwidth.
This user guide is designed not only to take you step by step through the setup and installation process and through the various menus and controls but also to serve as a resource to make educated, thoughtful decisions about encoding in general and do help you understand what’s really happening to your audio as it goes through the encoding process.

Know Your Goals
The first step to successful processing – and this applies to ANY processor, not just Omnia.9/XE - is defining your goals. Whatever those goals are, Omnia.9/XE is capable of getting you there.
You may wish to maintain as much quality as possible while increasing loudness somewhat over your existing processor. Or you might want to create very consistent source-to-source spectral balance and develop a “signature sound” for your station.. In any case, it is best to start with a goal in mind and work toward it carefully and deliberately.
Tweaking and Fiddling
One big temptation when installing a new processor is fiddling with every available control, and there is no shortage of those in Omnia.9/XE! There’s really no better way to find out what each control does, but experimentation and exploration are probably best done “on the bench” as it were before you put your new acquisition on the air. That way, you’re free to tweak away without having to worry about jeopardizing your on-air sound or being unnecessarily timid about making adjustments because you don’t know what affect they will have.
Another suggestion for getting to know your way around Omnia.9/XE is to find a factory preset that you like and then go exploring in the various menus to see how that sound was achieved. For example, let’s say you find a preset with a smooth, open sound which matches your general processing goal. As you explore, you might find some controls set as you would expect to deliver that sound, but you may also find some unexpected settings that make more creative use of Omnia.9/XE’s controls. There is much to be learned by studying.
Once you are comfortable with navigating through Omnia.9/XE’s menus and have a good understanding of how its controls operate, you’re ready to take it for a live test drive.
Choosing a Preset
Regardless of whether you end up using a supplied preset “as-is” or make adjustments to customize your sound, you must start with one of the factory presets. We recommend you find one that most closely matches your goals and then make any modifications from there as needed.
Most processors use radio format names to try and define their sound but then go on to explain there’s no reason a rock station shouldn’t try out the “Country” preset – which is very true. As a rule, Omnia.9 takes a deliberately different approach and most of its presets don’t give you any hint as to who should use them (or how) in the hopes that you’ll “step out of your box” a bit and explore.
If your Country station sounds great on the air with settings that might mimic an “Urban” preset - with a slamming low end and a nice open mid-range – the last thing we want to do is make you second guess yourself because the preset name doesn’t match.

General Processing Advice
Making and Saving Changes
Human nature is fickle; the human ear adapts and tires quickly; and Omnia.9/XE is powerful! With those things in mind, here are some recommended “Do’s” and “Don’ts” when making and saving changes to presets:
•DO resist the temptation to constantly fiddle with every control right after you put Omnia.9/XE on the air.
•DON’T make hasty, radical changes.
•DON’T make adjustments to too many parameters at once – that makes it difficult to determine which of the adjustments is actually responsible for the changes (for better or worse) you’re hearing on the air.
•DO look to the Band Mix and Parametric EQ sections first to achieve the spectral balance (aka “signature sound”) that you’re looking for. These are powerful adjustments, and a little EQ can go a long way. This is generally “safer” than making adjustments to the target, attack, and release rate controls as it is sometimes difficult to know how the different compression stages interact with one another on all material.
•DO take breaks when adjusting your processing. Ears tire quickly, and if you stay at it too long, you’re almost sure to make changes influenced by fatigue.
•DON’T turn your monitor speakers up too loud when making adjustments. High listening levels cause ears to tire even more quickly and mask both gain riding artifacts and distortion. Most listeners play the radio in the background, and problems tend to be more audible at comfortable listening levels.
•DO make small adjustments, particularly to critical controls like Limiter thresholds.
•DO take the time to calibrate a set of high-quality reference monitors (a process described in detail in this manual) so that any changes you make aren’t skewed by colorations of the speakers or room.
•DON’T rush the process. Use the “sleep-on-it” method when you’ve reached a point where you are mostly satisfied with the sound, and then re-evaluate it the next day. If it still sounds good, STOP. If it doesn’t, make a few adjustments and walk away for another day.
•DO use the “Save As” method of naming and saving your custom presets rather than over-writing them. This will allow you to return to any point in your adjustments if you get too far “off track” and keep you from having to remember (or guess) what changes you’ve made along the way.
Many Omnia.9/XE users have asked if they can make their own custom presets “from scratch.” All custom presets start life as a factory preset, but the most straightforward, neutral-sounding factory preset is “Reference Settings,” and as such provides the closest thing to a “blank canvas” possible for building your own preset from the ground up.

Installing the
Omnia.9/XE Software
Installing the Omnia.9/XE Software
Installing the Omnia.9/XE Software
The Installer File
The installer is an executable (.exe) file that by default will install a shortcut to the Omnia.9xe start menu group on your Windows desktop. To begin installation, double-click on the “omnia9xe_installer_.exe” file. This shortcut will open an Windows Explorer window containing 7 individual shortcuts:
•NfRemote
•Omnia9xe App
•Omnia9xe Config
•Omnia9xe Service Install
•Omnia9xe Service Remove
•Service Control Manager
•Uninstall Omnia9xe
To upgrade, simply install the newer version on top of the old one. Uninstalling first serves no purpose as settings are kept in C:/programdata/Omnia9xe and are not removed by the uninstaller.

Initial Setup and
Configuration
Initial Setup and Configuration
Initial Setup and Configuration
Entering Your License Key
Begin the initial configuration by opening the “Omnia9xe Config” shortcut, selecting “License”, selecting an available Slot #, entering your license key, and then selecting “Activate”. The slot in which you entered the key will indicate the key number and the number of licenses in green. Please note that one license key can only be activated on one machine.
Using a Demo License Key provides full program functionality but inserts a voice-over periodically announcing that you are using a demo version. Stations running in demo mode are clearly marked as such in the user interface.
Setting the Number of Stations and Devices
A “Station” refers to a unique individual program source. A “Device” refers an audio interface. Multichannel sound cards can have more than one device (for example Record 1-2, Record 3-4).
Begin by selecting the “Settings” and then “Base Configuration”.
10
Initial Setup and Configuration
•Choose the number of stations by sliding the “Number of Stations” control. If you are using a mouse, hold down the left mouse button while dragging the slider. On a touch-screen tablet or PC, press and hold the slider while dragging it. Remember that any stations in excess of the number included with your license key(s) will run in demo mode and include a voice-over.
•Set the number of ASIO devices (Audio Streaming Input/Output) or WDM devices (Windows Driver Model) as appropriate for your particular configuration using the respective sliders.
•Choose a sample rate (44.1 or 48kHz) keeping in mind that this is a global setting and all stations must use the same sample rate. If you are using the Axia Livewire driver, you must use 48kHz. Please note that all encoders have high-quality sample rate converters at their inputs, so it is still possible to output a 44.1kHz stream even when using a 48kHz global sample rate.
•Select “Settings” then “Encoders per Station” to select the type and quantity of encoder(s) needed. Encoding formats include AAC, MP3, WMA, and MP2. Each format can support up to four independent streams with different encoder settings per station. A detailed explanation of the benefits and drawbacks of each encoding format along with some recommended settings is included in the section on encoding.
11
Initial Setup and Configuration
Configuring Audio Devices
Select Audio Devices to display an individual menu for each specified ASIO and WDM device.
ASIO Devices
ASIO is the cleanest and most robust option and is supported by nearly all professional sound cards. It provides a direct link between the software and the audio interface (sound card). It also provides access to all audio channels from within the Omnia.9/XE software.
12
Initial Setup and Configuration
WDM Devices
If ASIO is not an option, you may use a WDM audio interface instead.
•Choose Kernel Streaming (KS), DirectSound (DS), or Wave from the Interface drop down control.
•Kernel Streaming is the preferred choice as it is a hardware-direct method of connecting to the WDM audio driver and therefore bypasses native Windows sound settings and sample rate conversion.
•DirectSound is an emulation that provides greater compatibility by playing audio through the system mixer, but quality is often compromised and Windows will be responsible for converting audio to/from the native format of the sound card.
•Wave is the default setting because it provides the greatest compatibility and allows multiple applications to access the sound card simultaneously. Like DS, it is an emulation. It is not as robust as KS, particularly on a system whose resources are being taxed.
•Choose the audio source from the Device dropdown control.
•Select the number of channels from the Channel dropdown control (Stereo, 5.1, or 7.1).
•Set the Buffer Size and Buffer Count from their corresponding dropdown menus. The default settings are conservative and “safe” and set to a buffer size of 1024 and a buffer count of 8.
•Check the “Run Test” box and verify a block jitter reading of under 50%. For DirectSound and Wave, you can reduce the block jitter by selecting a buffer size that results in a whole number of milliseconds per block. For example, 882 for 44.1kHz or 960 for 48kHz, both of which result in a nice even 50 milliseconds of audio per block.
13
Initial Setup and Configuration
WDM Speaker Output
While most monitoring will probably be done remotely through the NfRemote client, the WDM Speaker Output optionally provides a means for local monitoring. The speaker (monitor) output runs on a separate clock with an asynchronous sample rate converter to prevent periodic audio glitches resulting from the output being on a different clock than the input source.
Opening the Omnia.9/XE App
Launch the “Omnia9xe App” to start the Omnia.9/XE software in order to verify system performance from several key hardware indicators.
•Examine the CPU Load meter on the top Menu Bar. The maximum safe reading is 70%.
•Select the Common menu, then System, then Audio I/O Status for each device to see the current actual sample rate and the amount of block jitter. This value should be less than 40% with the default settings. Adjusting buffer size as described above can result in values of under 10%.
Installing and Configuring the NfRemote Client Software
The Omnia.9/XE remote interface software, NfRemote, is a separate “client” software application that can be installed on nearly any desktop, laptop, or tablet PC of reasonably modern vintage running on Windows 2000, Windows XP, Vista, Windows 7 or Windows 8. A shortcut is included in the Installer file.
It is possible to configure Omnia.9/XE from the host computer, but this can only be accomplished when the Omnia9xe Service is not running and your streams are not up and running live. The NfRemote client
14
Initial Setup and Configuration
allows remote access to the Omnia.9/XE service while it is running on the host PC. With few exceptions, it looks and operates just like the interface in the Omnia.9/XE Application.
Before you can connect remotely to Omnia.9/XE, the host PC - that is, the computer running the actual Omnia.9/XE software - must connected to your network and must have an IP addressed assigned to it. Using a password is not required when you are running NfRemote on the host PC, but is necessary if you wish to install NfRemote on any other PC in order to connect to Omnia.9/XE.
Double-click on the NfRemote shortcut to begin the installation.
Once installed and running, enter the IP address and password of the host PC into the corresponding fields of NfRemote and click Connect.
A complete explanation of NfRemote controls and functionality is provided in Chapter 14, “Using the Omnia.9/XE NfRemote Client Software”.
Understanding and Installing the Omnia.9/XE Service
The actual processing and streaming by Omnia.9/XE is done as a Windows Service rather than as an executable program. The final step in launching your stream is to start this service. When the Omnia.9/XE service is running, you must use the NfRemote client software to access the user interface.
However - please read and understand the warning below. It’s the only time you’ll see red text in this manual, so you know we’re serious. Really. We’re not kidding. We’ve seen the future if you don’t and it’s not pretty.
Warning: It is imperative to understand that it is not possible to open the Omnia.9/XE Config or the Omnia.9/XE App applications to make changes to basic configuration settings (such as number of stations or number of encoders) while this service is running.
Therefore, DO NOT launch the Omnia9xe Service install file until you have have verified that your configuration is correct and your CPU and hardware can handle the workload as described above.
Because the service for Omnia.9/XE initiates before the Windows user interface, if the CPU “pegs out” due to excessive demands from Omnia.9/XE, the Windows GUI may never appear at all, leaving you with no way to terminate the very service causing the overload and resulting in a bricked PC.
Once you understand the importance of testing your system before starting the service and have verified that your hardware is up to the task, you can install the Omnia.9/XE service by opening the shortcut labeled Omnia9xe Service Install from the installation shortcut folder.
A shortcut to the Windows Service Control Manager is also included in the installation folder. You can start and stop the Omnia.9/XE service from within the manager. If you want to remove the service completely (either temporarily as an extra safeguard when running the Config App or Omnia.9/XE app, or permanently) a shortcut to do so is provided to the Omnia9xe Service Remove file in the installation folder.

Omnia.9/XE Home Screen
and User Interface
Omnia.9/XE Home Screen and User Interface
Omnia9/XE Home Screen and User Interface
Opening the Omnia9xe App displays the user interface which is divided into four basic sections: The Menu Bar, the Display Windows, the Navigation Bar, and the Controls for the current menu.
The Menu Bar
The Menu Bar, visible at the top of every screen, shows the station currently being viewed, a “friendly” customizable location reference field, the name of the host PC, the current instance, the CPU load, a Menu button, and 6 display preset buttons.
•The Menu button on the front panel has six options: Displays Only, Expert Mode, Lock Position, Maximize, Full Screen, and Close Window.
•Selecting Displays Only allows whichever displays you have selected to occupy the entire window while hiding the controls, useful when you want a more detailed view of the processing meters or an oscilloscope or FFT display. Clicking or tapping anywhere on the screen returns you to the normal view, which shows both displays and controls.
•The Expert Mode control toggles between Expert and Non-Expert views and is explained in more detail below in the “Navigation Modes” section.
•Lock Position makes the window non-moveable and secures it in its current position on the screen. This is especially handy on a touch-screen device if you prefer not to maximize the window.
17
Omnia.9/XE Home Screen and User Interface
•Selecting Maximize resizes the window to occupy the entire screen and duplicates the function of the standard Windows “maximize” button. Once maximized, the window can be resorted to its previous size by selecting “Restore” or using the Windows restore button.
•Full Screen also maximizes the window but removes the standard Windows frame and its minimize, maximize, restore, and resize buttons as well as the task bar and the start menu. Selecting “Restore” from the Menu exits the Full Screen mode.
•Selecting Close Window, not surprisingly, closes the application window.
•The Display Preset buttons, numbered 1 – 6, let you create and save six separate Home screens. For example, you may wish to devote one display preset to nothing but the Undo and Processing Meters to display these parameters in greater detail. Or, you could devote an entire display preset to the oscilloscope and monitor various points along the processing path to see what the various stages within Omnia.9/XE are doing to the audio signal.
Navigation Modes
The Omnia.9/XE User Interface (UI) is set up in “tiers”.
The first tier always contains the highest level (most general) menu options in the form of buttons. When selected, these buttons take you to a second tier of menu options, which are also buttons, but of a more specific nature. The third tier is made up of controls.
There are two navigation modes available from the Menu button: Expert and Non-expert. The default mode is “Non-Expert.” Both modes give you access to the same number of controls; the terms refer only to the way those controls are displayed and laid out.
The Non-Expert mode shows fewer controls at once and has a cleaner, less cluttered look, especially in a small window. However, it requires more steps to navigate through the menu system.
The Expert mode shows all tiers and available controls for selected menu sections at once. This provides more direct access to items located deeper in the menu structure but may be visually more intimidating to inexperienced users. It works especially well on a large screen where you have more real estate to work with.
Non-Expert Navigation Mode
The non-expert mode is the default view.
In this mode:
•The top portion of the screen is devoted to the display windows.
•The bottom portion of the screen shows the buttons or controls for the current tier.
•In between these two areas is a navigation bar that shows you exactly where you “are” within the menu system along with navigation arrow buttons that when selected allow you go forward or backward to places you have recently visited.
•Clicking and holding either of the arrow buttons will bring up a list of these places so you can re-visit them directly.
•You can make individual portions of the window larger or smaller to devote more or less on-screen real estate to display windows or control windows by dragging up and down on the re-size bars.
18
Omnia.9/XE Home Screen and User Interface
Expert Navigation Mode
Clicking on the Menu button and selecting “Expert Mode” allows more direct control by displaying more information at once.
In this mode:
•The navigation bar and arrows are eliminated.
•The top portion of the screen is devoted to the display windows.
•The middle portion of the screen shows the first, second, and third tier buttons.
•The bottom portion of the screen shows the third tier controls.
•You can make individual portions of the window larger or smaller to devote more or less on-screen real estate to display windows or control windows by dragging up and down on the re-size bars.
19
Omnia.9/XE Home Screen and User Interface
The Three Basic Control Types
There are three basic types of controls in Omnia.9/XE:
•On/Off buttons - These controls toggle on and off, thereby enabling or disabling the associated function.
•Drop-down menus provide a drop-down list of options. Scrolling over each option highlights it, while a tap or left-click on a mouse selects it.
•Sliding controls - Selecting a slider control highlights it. Tapping and holding (or left-clicking and holding with a mouse) a slider allows you to drag it back and forth to adjust its parameter. When using a touch interface, dragging the slider faster will accelerate the rate of change. As long as you haven’t lifted your finger (or released the left mouse button) you can continue to drag the slider beyond the edge of the control all the way out to the very edge of the display. Because it is often difficult to make fine adjustments on a small screen, in a virtual machine or through remote desktop, when using a touch interface you can double-click a slider to bring up a pop-up window with two large sliders, one for “coarse” adjustment and one for “fine.”

Final&
Output&
Level&
Downward&
Expander&
•The ITU BS.1770 Input meters indicate the level of the unprocessed source audio coming into each station processed by Omnia.9/XE with floating peak indicators above each bar.
•The AGC meter window shows the levels and action of the Input AGC and the Wideband AGC1 compressors. It also shows the level of the Wideband AGC2 section when it is enabled and positioned before the multiband section.
Depending upon the settings of the various Input and Wideband AGC1/AGC2 controls, the meter scale can display levels below threshold (positive numbers) as well as levels above threshold (negative numbers). When the meters dip down below “0” the compressors are above threshold and therefore in a state of gain reduction. When they rise above “0” they are below threshold and in a state of gain increase. The combination of Input AGC, AGC1, and AGC2 gain is added together to determine the total amount of AGC gain in place.
•The Input AGC levels are indicated by a bright yellow bar. The Wideband AGC1 levels are shown as a dark orange bar extending beyond the Input AGC meter. Wideband AGC2 levels (if this compressor is situated before the multiband section) are shown as a second, darker orange bar beyond the AGC1 meter.
•The Multiband meter window shows the levels and action of the AGC, limiter, and noise reduction sections for each band (ranging from 2 to 7 depending upon the preset employed). As is the case with the AGC metering section, the scale will change based upon the settings of various multiband controls.
•The AGC level in each band is indicated by a bright yellow bar. The multiband limiter for each band is represented by a bright red bar that flashes beneath the AGC level. The multiband noise reduction for each band is shown by a dark red bar that appears to drop down from the very top of the meter. Gating - the condition in which release is significantly slowed down - is indicated by a dark red ribbon at the bottom of the multiband AGC meters. Freezing - the condition in which
22
Reading the Processing Meters
release stops completely - is indicated by the same red ribbon, but slightly brighter. Dry voice detection is indicated by a green ribbon in the same location.
•If the Wideband AGC2 compressor is enabled and placed after the multiband section, or it is used in one of its Bass modes, its meter will be displayed separately to the right of the multiband display. The Wideband AGC3 meter will appear after the multiband section as well if it has been enabled.
•The Multiband Stereo Enhancer meters will be displayed if the current preset employs this feature. Yellow bars extending from the middle outward toward the left and right of the display indicate a widening of the stereo image. Red bars extending from the left and right edges toward the middle indicate a narrowing of the stereo image.
•The Final Limiter meters indicate the amount of limiting activity in the final look-ahead peak limiters.
•The Output Meters indicated the final processed output levels.

The Home Menu
The Home Menu
The Home Menu
The Home Menu represents the highest level menu available in the user interface. It includes sub-menus for each individual Station and for Common settings.
If you ever lose you way when navigating the menu system, going back to the Home Menu will get you quickly back on familiar ground.
25
Chapter 7
The Common Menu
The Common Menu
The Common Menu
The Common Menu contains two sub-menus, System and License, which provide access to global and configuration settings including licensing information. Some of this information is also found in the Configuration app but duplicated here for convenience. If you specified a device as a WDM Speaker Output during configuration, it will also appear in the Common menu.
System Menu
The System Menu provides access to the System Information, Network Information, Audio I/O Status, Base Configuration, Password, Outbound Connection, and HTTP Access sub-menus.
27
The Common Menu
System Information Menu
Statistics for CPU Load, available memory, system up time, software version and GUI version are located here in the System Information menu.
Network Information Menu
Networking information including Host Name, IP Address, MAC Address, number of active remote connections, Remote Port number, and current user is listed in the Network Information Menu. There is also a user-defined text field for Location which changes what is displayed in the Location window in the Menu Bar. This location text is also automatically displayed in your connection list when using the NfRemote client.
Audio I/O Status Menu
Each ASIO and WDM audio device specified in the Configuration App has a corresponding Audio I/O Menu that indicates its exact current sample rate, % of block jitter, and buffer size. Jitter for ASIO devices will include the number of jitter warning events (“W” - over 40%), high jitter events (“H” - over 70%), and resets (“R” - if the device stalls completely and needs to be reinitialized).
28
The Common Menu
Base Configuration Menu
The number of stations and the number of each encoder instances for each format can be set in the Base Configuration menu as described earlier in the section on Configuration.
Password Menu
In order to access Omnia.9/XE remotely from the NfRemote client it is necessary to enable password protection by entering and re-entering the password in the text fields from the Password Menu.
Note that this password ONLY provides protection when using the NfRemote software. It does NOT secure the PC running the Omnia.9/XE software. Good security practice (and common sense!) dictate that the host PC be secured with a Windows password of adequate strength.
29
The Common Menu
Outbound Connection Menu
Connecting remotely to Omnia.9/XE is normally involves using the NfRemote client software to initiate a a connection. The Outbound Connection menu allows this to happen in reverse by providing a means by which Omnia.9/XE can initiate the connection to an NfRemote client. This can be especially useful when working with Omnia Support as it allows communication outside of the local area network (LAN) without having to set up port forwarding.
Details for setting up a corresponding inbound connection are provided in Chapter 14, “Using the NfRemote Client Software”.
•Enter the IP address (or host name) and listening port of the computer running NfRemote using the following example as a guide: 127.0.0.1:2000 (the IP address and the listening port with a colon in between). The IP address and port should match those on the NfRemote end of the connection. Three connection slots are available.
