What is a spectrum analyser?

[moresound]

I just used one for the room back when I was doing sound for a huge-ish rock club. The owner threw it on the rack of tools when he was feeling benevolent one day (also sent me out to buy a dozen SM58s... must have made bank off the college kids or something the previous week, I didn't ask. It kind of helped I guess but he was far more interested in it than I was. Ears are good too (well back then they were). The audience hears what you hear, right? Mostly it just looked really cool and made outsiders watching on think I was doing very complicated things beyond their understanding (my boss included).

We always had one in the rack while touring to shoot room we hadn't been in as yet.
But during the show it was just on for no reason and girls mostly would come up and to start a conversation they would ask "what does that do"? we deemed it *The Chick Catcher* ..... We kept it around for a long time.
