Cobalt's Loudness Meter software works with the award-winning OGCP-9000 Remote Control Panel and our new WinOGCP Desktop Virtual Control Panel to provide a flexible, complete solution for ingest or on-air loudness metering, assessment, and records. An intuitive touch screen control interface offers simple “pushbutton” session start and stop along with clear-cut clear pass/fail loudness assessment for QC operators.
True peak level detection, error tracking and logging, and other detailed criteria offer detailed assessments and logging for admin/engineering. Configurable automatically triggered sessions and report generation (timecode range, signal level-based, and automatic daily session start/stop/restart) provide for automation-based session and records generation to help document compliance with loudness regulations.
Easy to use, yet comprehensive, the option ensures thorough audio level and loudness assessment, and is ITU BS.1770, ATSC A/85, and EBU R128 compliant. Because cards forward the audio measurement data to the control panel over your plant’s Ethernet network, the control panel does not need co-location or insertion within the video/audio stream.
The Audio Loudness Meter software works with a wide range of Cobalt cards. The software can be ordered with card purchase, or activated later using a downloadable feature key via free DashBoard™ remote control/monitoring software (no need to remove or replace card.)
