LQL Screen 2

The LQL (Loudness Quality Logger) program is a dedicated tool for logging, true-peak data analysis and reporting, which is a natural extension of the innovative software options available for TouchMonitor.

LQL enables you to derive data directly via an IP-connection from a capable TouchMonitor, as well as from external storage media such as a USB stick. You also get dual limit weighting, status information, marker and various other reporting features.

The software is free of charge and available for Microsoft Windows 7 and Windows 8, however you will need an LQL license to enable TouchMonitors to support data export and additional display functions. For time code based logging, a separate license is required. LQL is provided by RTW. 

To enable logging, you have to update the firmware of your TouchMonitor to v 4.50.

  • Loudness History at a Glance

    Integrated, Momentary and Short Term loudness on an easy-to read graph stretching 72 hours back in time.
  • The Ultimate Logging Display for Multiple TouchMonitors

    Collect data from multiple TouchMonitors and store externally.
  • Loudness Analysis Made Easy

    Log realtime or time code based and export status overviews and reports.

Loudness History

 

Looking at your loudness history back in time is easy with LQL. But to make it even more flexible, you can set A and B markers to zoom in on specific points such as a particular program, or a specific commercial block. 

The visual graph streches as far back in time as 72 hours, allowing you to get an overview of Integrated (I), Short Term (S) and Momentary (M) parameters, as well as values for Max true Peak, Max Short Term and Max Momentary within the selected time frame in a matter of seconds.

Ultimate Logging Display

 

With LQL you can collect loudness data from multiple TouchMonitors and store externally for easy access at a later point. 

Simply connect multiple TouchMonitors on a LAN network and derive data directly via an IP-connection or from external storage media such as a USB stick.

Loudness Analysis

 

Obviously an advanced logging tool like LQL is perfect for analysis and evaluation, and to make it easy for you to find specific programs or other types of content post-transmission, you can choose to log via time code (time code license required). 

This way, you can easily navigate through your loudness history and pinpoint critical areas or programs in seconds.
