J*AM Jünger Application Manager
All current Jünger Audio devices are compatible with the J*AM Application Manager Software, a Windows™ platform that provides network based real time measurement and logging of loudness and true peak values.
As loudness based normalization is rapidly being adopted around the world, broadcasters are required to measure loudness values to ensure compliance with local regulations, and often to maintain a log of historical values should they ever need to respond to questions for viewers or authorities.
The Jünger Audio J*AM Application Manager is a software package that runs on WindowsTM and allows for real-time monitoring and measurement of loudness and true peak input and/or output values. When coupled with the optional Loudness LoggerTM license, all measured values can be stored in log files anywhere on the network for future recall. All current broadcast audio loudness standards are supported including ITU-R BS.1770 (1, 2 and 3) and recommended practices ATSC A/85 (2011/2013), ARIB TR-B32, Free TV OP-59, Portaria 354 and EBU R128.
- J*AM Application Manager
Available as a free of charge download, the J*AM software can be installed anywhere on your network and communicates via Ethernet with multiple Jünger Audio devices simultaneously. An intuitive user interface means that set-up and configuration is straightforward and all currently connected devices are displayed in the main control window. An on screen level meter displays bar graphs of peak input and output for both stereo or 5.1 channel processors along with an indication of the gain changing activity of the leveler, dynamics and limiter sections. In addition, numerical readouts display both short term and integrated (LUFS or LKFS depending on the selected standard) loudness input and output values.
- Loudness Logger™ License
An array of extra features and functionality can be accessed through the addition of the Loudness Logger™ license option. Administered by the use of a USB dongle, a separate window can be opened which displays a live plot of short-term loudness and true peak input/output values. A loudness distribution graph also shows the evolution of pre-treated compared to post-treated signals over time. The license also allows for logging of measured data from all channels of each connected device to a folder location anywhere on the network. The frequency and duration of the log files can be easily customized. The log files themselves are stored in csv format but to aid future interpretation, a comprehensive log file analyzer tool is included. This opens the selected log file and rebuilds the stored data into its original graphical plot format. The date and time stamp makes it simple to look back any specific point within the file. A zoom function allows very precise analysis of the selected region whilst a log file comparator can display two plots simultaneously to allow a side by side direct comparison.
