Introducing our AES, NY paper "Automated Assessment of Surround Sound"
and the Broadcast Engineering article on Audio Monitoring

Qualis Audio designs, manufactures, and sells intelligent surround sound monitoring systems for broadcast, studio and post production applications. The Sentinel provides comprehensive and continuous monitoring of surround sound program material. Using sophisticated algorithms to rapidly detect common errors and quality problems, it sounds alarms and can deliver remote error notification by email. All measurements and alarms are logged for later recall and examination. Real time measurements or logged data may be accessed using a standard web browser metres, miles or time zones away. Quick intuitive visual indicators continuously provide feedback of several important surround audio quality parameters with distinctive color change instantly showing problems.
