Lake Oswego, OR (May 12, 2010)--Qualis Audio has launched the AES/EBU and SDI versions of Sentinel, a network-based, automated surround sound monitor that performs unattended monitoring of surround program material.
The human interface software has been revised to include graphical display of loudness and other measurements vs. time. These graphs display both real time and logged data with transitions between the two.
The Sentinel reportedly performs stereo and mono downmixes internally and compares these to the original surround mix. If content present in the surround mix is missing from either the stereo or mono mixes, it flags a warning or error. The user is freed from continuously watching and interpreting a screen, allowing more attention to other aspects of producing, evaluating and transmitting the program.
