LQL - Loudness Quality Logger RTW

Mainly the LQL – Loudness Quality Logger software consist of a kernel collecting and storing data in the background. A user interface is provided to connect and monitor the devices and for display of aquired data. The user interface itself consists of a main window giving an overview and additionally selectable detail windows.
The examples shows the main window in the background, covered from two detail windows with differently selected parameters respectively belonging to one audio group. The rear detail window is freezed, the front one is permanetly drawing values over time (LIVE).

The main window gives an overview about the connected audio devices and their audio groups being enabled to deliver Loudness and TruePeak data. In addition, quality of service for the connection and data is indicated by the colors of the traffic lights. TouchMonitor devices as well as their audio groups need to have biunique names to be able to communicate with LQL. Using the Add dialog, the LQL will access the device with its IP address and indicate it by its name.

Data being collected in the background will be calculated and displayed in the detail window as a graph according to the selected values and scaling factor. Two of four values can be displayed in any combination at a time with enabled (Live) or disabled (Freeze) continuously updating graph. In the numerical display section all values are permanently visible. The displayed time stamp on the time line (below the graph) depends on the time settings of the selected TouchMonitor and is also continuously updating. Start and End time of data capture is displayed below the numerical section. A rough estimated point of time can be refined using one of the scaling factors or be jumped to by using the GO TO TIME function. The MARKS ON function allows to place markers in the graph selecting a section that will get a numerical recalculation.

In the menu settings of the LQL, the Main Alarm Threshold Set menu is used to set main limits according to legal regulations or the requirements of current loudness standards for example.
The Secondary Alarm Threshold Set menu is used to set additional thresholds according to in-house regulations for example. They should be set to a tighter value than the corresponding main limits to
assure the possibility of potential corrections of the actual program material. If secondary limits are indicated as exceeded, the engineer can regulate the program early enough to keep it in balance to the
main limits allowed.
The alarm thresholds set in LQL represent individual helpful marks, but they don't perform any modifications to the actual audio streams.
