The iLM8 measures the perceived loudness of eight channels of program audio and displays the results in an easy-to-read numerical format with a moving average over time, eliminating the variations with engineers interpreting traditional VU or PPM indicators (neither of which can measure perceived loudness).

If changing from one to two tones, the energy of each of the two tones is exactly half of that of the single tone. While the amount of audio energy never changes, the perceived loudness increases as the energy spectrum spreads out across more tones (Johnston, 2006). J.

The most valuable tools in determining loudness in your program material include: iLM8 Intelligent Loudness Meter – Operators should position iLM8 at various places within the signal flow to objectively verify that audio loudness levels are within tolerance. Limited operator training is required to learn the basics of perceptual loudness measurement and management.

‘squashing’ the audio and removing essential audio dynamics. With visual feedback presented from the iLM8, a new solution has emerged that enables engineers to measure perceived loudness correctly and take appropriate corrective action on the fly, imitating methods used by audio mix engineers who actively ride their faders.

AES INPUTS - Four 75 BNC connectors will accept the AES3 digital audio stream. For iLM8 to work properly, the following channel inputs must be maintained: 1/2 - Left and Right Channel (Front) 3/4 - Center and LFE 5/6 – Left and Right Surround AUX –...
Page 15
NETWORK - Used for logging or to update iLM8’s firmware. To connect directly to a PC without use of a network switch or hub, a crossover cable is required. Firmware updating is accomplished via UDP Port 44600.

DHCP address by default. Device Name: Allows you to change iLM8’s name as reported to DNS. Press ENTER while the cursor is over this field to go into data entry mode. Turn the rotary encoder to scroll through the available choices of letters (A-Z, 0-9 and _ (underscore)) and press ENTER to move on to the next field.

Target Level: Sets the desired loudness level threshold. Target can also be set directly from the home screen. (-1 to -31dB, Default: -24) Short Averaging Time: The amount of time that iLM8 will sample audio to determine the short term combined average level. (1 to 10 seconds, Default: 3) Right Display Field: Selects if Infinite Average or True/Standard Peak values are shown on the right display field of the home screen;...

The Algorithm Meters menu contains all the real-time loudness readings that iLM8 generates for the audio input. Each measurement is rounded up to two decimal places of precision. Selecting Enable Keylock will enable they keylock immediately and exit to the home screen, inhibiting all key or rotary encoder inputs.

The DaySequerra Remote Dashboard software will allow remote monitoring and logging of audio loudness as it is measured by iLM8. Double click the installation icon to install the program. A shortcut will be created on your desktop. If you wish the software to start automatically with the PC at login, place a copy of the shortcut into your Startup Windows program folder.

Un-configured Settings Tab Network Settings: Enter the IP address of the iLM8 unit to be monitored. The IP address can be found on the unit by navigating to the SYSTEM MENU, then NETWORK. For more details, see the networking section of this manual. The UDP port should remain set at 44600.
Page 30
The program icon should change from red to green after communication has been established with the unit, and the iLM8 unit will illuminate the LOGGING LED. Switch back to the Surround tab to view the program in operation. If a setting has been changed in error, press CANCEL to revert all settings to their previously saved state.

1. Title Bar: Shows program name, along with short term and infinite average measurements for both the Surround and AUX inputs of the iLM8. Pressing the minimize button will minimize the application to the Windows task bar, where as clicking the close button will minimize the application to the system tray.
Page 32
4. Combined Measure History: The last 40 seconds of the short combined average is displayed on the graph. A heavy horizontal line shows where the target value on the iLM8 is set. Combined average and infinite average are shown in numerical form as well, with the colors changing to show the level of loudness.
Page 33
If the Remote Dashboard software is not working, please check the following items before contacting technical support: 1. Is the iLM8 on the same physical network and subnet as the PC running the application? Make sure the subnet mask is configured to a broad enough scope.
