Audio Measurement

Accurate measurement tools that can act as a "watchdog" and can trigger alarms if any preset values are exceeded are an invaluable aid to ensuring compliance and comfort.

All current Jünger Audio devices are compatible with the J*AM Application Manager , a Windows™ platform that provides network based real time measurement and logging of loudness and true peak values.

The Jünger Audio J*AM Application Manager allows real-time monitoring and measurement of loudness and true peak input and/or output values.

When coupled with the optional Loudness Logger™ 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.

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.
