Introduction
DaySequerra’s iLM8 – Live Intelligent Loudness Monitor measures perceived loudness of up to eight channels of program audio using the industry-standard ITU-R BS.1770-1, BS.1770-2, and BS1770-3 with Eclipse Loudness Measure algorithms. This proprietary algorithm was developed by after extensive research into human hearing and perceived loudness.
Loudness is a perceptual property of an audio signal when it is reproduced acoustically. It is a complex non-linear function of amplitude, frequency and bandwidth. Current audio level meters measure the level of audio signals expressed as the amplitude of the signal - either the RMS (root mean square) voltage of an electrical signal or the sound pressure of an acoustical signal. Neither of these measurements, although widely accepted, provides accurate indications of how viewers will perceive the loudness of the audio programming.
The Eclipse Loudness Measure algorithm uses a perceptual model of human hearing to more accurately detect spectral and density differences, inter-channel relationships and temporal overlaps in any audio content, resulting in a more accurate perceived loudness measurement over time.
The iLM8 - Live 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).
To improve system reliability and up-time, iLM8 - Live uses a robust DSP-based processing platform rather than the PC-based approach to completely avoid broadcast disruptions caused by operating system lockups. The iLM8 - Live’s built-in high-performance headphone amplifier allows monitoring of any two user-selected outputs even in noisy background environments. A set of user-definable alarms can alert an operator of input loss, signal clipping and high or low signal levels referenced to the desired loudness level. An Ethernet interface provides long-term logging and field software updates capability. Whether pre-screening content at an ingest point or keeping tabs on the output of a broadcast air-chain, iLM8 is your key to reduce viewer complaints and improve audience satisfaction.

Measuring Loudness
Human perception of the sensation of an audio signal is properly called “loudness”. As early as 1933, research by Fletcher and Munson showed that human hearing sensitivity is largely based upon the frequency of the sound, as well as the sound pressure level (SPL). As humans do not hear sound using standard measures of intensity, measuring loudness based upon SPL or the root mean square (RMS) voltage of the electrical signal will not agree with human perception. The Fletcher/Munson Equal Loudness Curves show the limits human sensitivity of certain frequencies, especially low frequencies (bass) at lower sound levels (Fletcher & Munson, 1933).
In order to create a loudness measure that more accurately represents the human perception of loudness, frequency weighting (or equalization curves) are placed ahead of power measurements. This introduces the measures Leq(A), Leq(B), Leq(C) and Leq(M) – with ‘Leq’ attempting to relate the ‘L’oudness of an ‘eq’uivalent amount of energy in a standard signal, typically a 1 kHz sine wave. The most current weighting standard, ITU-R BS.1770 produces results known as LKFS that are referenced to a dB FS scale. While certain Leq(x) measures match more closely to human loudness perception than traditional SPL or RMS measurements, there are still many broadcast content types that cannot be measured correctly with a Leq(x) or LKFS weighting method.
For example, a narrowband signal may be perceived to sound softer than an equally intense wideband sound, depending on the relationship between rendering level, absolute threshold and signal content. Additionally, content with large amounts of low-frequency energy is often inaccurately measured by BS.1770 due to heavy low-frequency roll off (see weighting curves). This measurement will often vary from a subjective measure, especially in the short term; however this variance is acceptable in a long term measurement, as the values are smoothed over many seconds, minutes or hours. Small deviations between the instantaneous perception of loudness is often acceptable when using a meter solution to measure the loudness, as the meters usually offer an audio visualization method that human operators can use. Combined with their ears, the operator can make any decisions about any corrective action required.

To achieve a more accurate loudness measurement, the method should include critical bands in the measurement. Critical bands describe auditory filters within the human cochlea. (J. Allen, 2010). To illustrate this, a subject is presented with a single tone of a certain energy level, and more tones are added with equal energy in the critical bands – the total signal energy is kept constant regardless of the number of tones. 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).

Bronwyn Jones and Emil Torick created a revised CBS loudness meter in the early 1980s that consisted of eight filters, each covering three critical bands. This approach did prove to deliver better subjective modeling than traditional SPL or RMS measurements (Jones & Torick, 1982).
In 2004, Nielsen and Skovenborg published an AES paper that expanded upon the ideas of critical band loudness measures. This paper introduced a method called HEIMDAL, which separated spectra into nine bands via an octave filter band. While the HEIMDAL multi-band model did not achieve the complexity of cochlear modeling as shown by J. Allen, the method had the lowest error compared to any preceding loudness models (Nielsen & Skovenborg, 2004).
Despite the clear benefits of critical band analysis in loudness measurement, there are very few methods currently available to measure loudness this way in real-time for broadcast applications -- the extra processing required to accomplish it have prevented widespread adoption.

Using iLM8 - Live to Control Loudness
!
The most valuable tools in determining loudness in your program material include:
iLM8 - Live Intelligent Loudness Meter – Operators should position iLM8 - Live 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.
A Listening Ear – No amount of metering can replace the value of active listening. Broadcasters should use trained technicians who work in listening environments that accurately represent the consumer’s expected environment as a final line of defense against inappropriate loudness.
When measuring live content in real-time, operators can use short-term smoothed loudness measurements to confirm that the mix or overall program audio is adhering to broadcaster-established guidelines or a governing body’s mandated target. However, when content is stored for playback at a later time, an opportunity is created for non-real-time loudness measurement.
Each Leq(x) revision results in a different level of correlation between the objective measure and the human listener’s assessment of loudness. The lowest mean error score was achieved by the

A long term loudness measurement of an entire clip is referred to as an infinite average. To achieve the desired loudness level, this value can be used to update the Dial Norm metadata, thus affecting the audio’s perceived loudness when processed at the point of consumption by way of the set top box or, more recently, digital television receiver. Granted that not all viewers will have equipment capable of processing metadata or Dial Norm information, it is possible to control the perceived loudness by the application a fixed-offset to the audio content after the infinite average of an entire piece of content has been measured. While this may sound like the ideal loudness solution, it alone will never completely address loudness complaints.
For example, imagine that a movie starts with a dramatic scene where the first ten minutes consist of speech and sound effects measured at -31 LKFS. The second half of the scene includes a car chase measuring at -17 LKFS. The Dial Norm correctly describes the entire scene as -24 LKFS, however the viewer perceives the audio level as very low for the first half of the clip followed by audio that is significantly louder during the second half. While this extreme dynamic range may be acceptable in a movie theatre, it is typically not within the typical viewer’s home environment. The infinite average and fixed-offset approach has no way of addressing such intra-content issues.
Another challenge that fixed-offset correction cannot solve is how loudness is perceived in the context of playback. In this scenario, a TV program ends quietly followed by a high-energy commercial. Even if both pieces of content are properly prepared and played back at correct infinite average levels, an abruptly louder start to the commercial will create a jarring effect when played back immediately after the quiet ending.
Last century’s loudness solution was a fix-all audio processor that was situated at the end of the broadcast chain, controlling loudness by ‘squashing’ the audio and removing essential audio dynamics. With visual feedback presented from the iLM8 - Live, 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. When coupled with a proficient listening ear, the solution is easily integrated with existing broadcasting workflows, delivering the flexibility engineers need to adjust loudness levels in real-time, without removing any signal dynamics.

Short Loudness Avg. for L, R, C, Ls, Rs Channels – measures the Max Short Loudness average of an individual channel. (Left, Right, Center, Left Surround, Right Surround). The default integration time is set by the industry preset being used. The user can adjust this integration time from 1 to 60 seconds.
5.0 True Peak – measures the true peak for the surround channels in dB relative to digital full scale in 100 Msec increments.
2.0 True Peak – measures the true peak for the stereo channels in dB relative to digital full scale in 100 Msec increments.
Max – TP – measures the maximum true peak in 100 Msec increments for the surround channels in dB relative to digital full scale. Max True Peak holds the maximum true peak in memory until it is reset by the user. Max – TP is reset by resetting the infinite average. (select STOP/RESET/PLAY Inf. Avg. icon)
2.0 Max – TP - measures the maximum true peak in 100 Msec increments for the stereo channels in dB relative to digital full scale. Max True Peak holds the maximum true peak in memory until it is reset by the user. Max - TP is reset by resetting the infinite average. (select STOP/RESET/PLAY Inf. Avg. icon)
5.0 LRA – measures the loudness range for the surround channels. To accurately measure using LRA the calculation should always start from 0 LU. Resetting the LRA is accomplished by Stopping/Resetting the infinite average. (select STOP/RESET/PLAY Inf.
Avg. icon). LRA is derived from the Short-Term loudness using a relative gating process similar to that described above but with the gate set at -20. The LRA is the span from the 10% to 95% points on the distribution of Short- Term loudness values that pass the relative gate. The LRA is descriptive of the program material dynamic range. Using the 95% point allows occasional extremely loud events while the 10% point ignores modest silent intervals during the program. If the LRA exceeds about 15 it is likely that viewers will be unable to find a single volume control setting appropriate for the entire program.
2.0 LRA - measures the loudness range for the stereo channels. To accurately measure using LRA the calculation should always start from 0 LU. Resetting the LRA is accomplished by Stopping/Resetting the infinite average. (select STOP/RESET/PLAY Inf. Avg. icon).

Log&Files&
!
The Remote Dashboard software’s main objective is to log your program audio loudness and have those measurements available for compliance verification. A new log file is created each hour and runs from x:00:00 to x:59:59. A new file will be created immediately if any data log options are changed.
By default, measurement data log files are saved in the “logfiles” folder under the main Remote Dashboard application installation folder. A full day of logging each available data field once per second will consume approximately 27MB of storage space. Storage of files onto flash drives or other solid state storage devices is not recommended due to very frequent data writes the application makes and the “write endurance” of these devices.
Logs are saved in Tab delimited format and can be imported into any database application that supports the importation of external data. Log files may also be imported into Microsoft Excel or Microsoft Access. The first line of each log file contains a column header that labels what data is
contained within that column.
Log File Import Example
This brief procedure will demonstrate how to import the log file data into Microsoft Excel and render some simple graphs of the data. This procedure has only been verified to work in Microsoft Excel versions 2000, 2003 or 2007.
1. Open Microsoft Excel. In Excel 2007, click on the Data tab, and then click the Text button under the Get External Data group. In Excel 2000 or 2003, click on the Data menu, click Get External Data and then click Import Text File.
2 The Import Text File box will appear. On the bottom of the window, click the Files of type drop down
box and select All Files (*.*). Then, navigate to the location that the log files are stored in and select the appropriate log file. Double click on the file name or select the file and press the
Import button.
3 The Text Import Wizard will start. Press the Finish button, as no values on these pages will
need to be modified.
4 The Import Data box will appear and ask where in the Excel sheet the data should be inserted.
Press the OK button to select the default location (Cell A1) or select the alternate desired location and press the OK button.

5 The log file data is now displayed in Excel. Each column header contains the text description of
the data that is displayed.
6 In order to make a line graph, first select the data that will be displayed in the graph. Hold down
the control key and click on the column headers that contain the desired data. To only select a small portion of data from the log file, click the first value, hold the shift key, and then click on the last value.
7 In Excel 2007, click on the Insert tab. Click the Line button and then select Line under the 2-D
Line group. In Excel 2000 or 2003, click on the Insert menu, and then click on Chart. The Chart Wizard will appear. Select Line from the list on the left side of the window and then Line from
the icons on the right side of the window. Click the Finish button.
8. The Chart is created. It may be moved to another area of the spreadsheet or copied to memory and pasted in another application. The X axis (left edge of the graph) displays the loudness value and the Y axis (top edge of the graph) displays the sample number, in this example.

Maintaining an Accurate Clock
!
To have the data in log files correctly represent the program material measured during a particular time of day, the PC clock will need to be synchronized to a reliable clock or house source. Windows contains a NTP server client that will automatically set the PC clock to be the same as a remote clock.
1. Double click on the clock in the system tray.
2. Click on the ‘Internet Time’ tab.
3. Enter the time server address to be used, or use the public pool time.nist.gov.
4. Press APPLY then UPDATE now to ensure the server address can be contacted. A message will appear below the server address “The time has been successfully synchronized with (server) on (date) at (time). By default, Windows will typically synchronize the clock once per week. A message will be shown with the next scheduled update time.
5. To change the update frequency, open registry editor by selecting START then RUN and typing regedit at the prompt and pressing OK.
6. Navigate to the registry folder \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\Ntp Client.
7. If present, double click on the registry entry SpecialPollInterval. Change the BASE radio button to Decimal. The value data will show the update frequency, in seconds. This value may be modified to the required setting.
8. If the key is not present, select EDIT, NEW, then DWORD Value. Rename as SpecialPollInterval. Change the BASE radio button to Decimal. The value data will show the update frequency, in seconds. This value may be modified to the required setting.
9. Close registry editor.
10. Restart the time service by selecting START then RUN and typing cmd at the prompt and pressing OK. At the command prompt type net stop w32time && net start w32time. Type exit
after confirmation that the service stopped and restarted successfully.
Remote&Dashboard&Troubleshooting&
!
If the Remote Dashboard software is not working, please check the following items before contacting technical support:
1. Is the iLM8 - Live 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.
2. Is there a software firewall running blocking access to the UDP port 44600? Make sure the port is open, or the Remote Dashboard software is in your firewall’s exclusion or white list. Contact your firewall vendor for more support.
3. Is the iLM8 - Live running the latest firmware? Older iLM8 - Live firmware versions (< 4.01.00) aren’t compatible with Remote Dashboard.
4. Remote Dashboard is not creating any log files. Make sure the active Windows user has the proper permissions to write to the location specified for log files to be saved.
