What If?
Pete Putman, CTS, ISF
I recently relocated my offices and studio, and I am still missing things I packed several months. Every few weeks, I stumble across another box and mutter to myself, ?so that's where it wound up.?

This edition of the magazine was published as the war in the Pacific was winding down to its explosive climax....

NSCA 2007 Hot Picks
Mark Mayfield
If not quantity, at least there was quality. Of course, we're talking about the new products featured at the NSCA Expo 2007 in Orlando, Fla. But if you came looking for real ?new? technology, you were probably disappointed. That's more a sign of a maturing industry than a criticism of any manufacturer's technological prowess. In fact, what characterizes this year's...

Pat Brown

It is important to have an abstract understanding of the methods used to collect data to know what can and cannot be predicted about sound system performance. This translates into better designs and fewer surprises....
Nobody's Watching
Tim Kridel
In the 2002 movie ?Minority Report,? the government's Precrime Unit identifies crimes before they are committed and jails the would-be offenders.
