The idea, IIRC, was to have this constant audio stream on the background, so one could easily detect anomalies without having to look at a dashboard all the time.

I can't seem to find this tool anywhere now, no matter how much googling I try. Maybe I'm trying the wrong terms, or something.

But, since it's been quite a while, I am also wondering if there are any other tools lately that target this space. All I could find was peep (http://peep.sourceforge.net/intro.html), but this seems to be legacy, and even then only for network monitoring.

Does anyone remember about the tool I described, or know about some related software?
