Sacred Haven of Debauchery

This isn't just the case with music. I studied to be an engineer at university, and I didn't really understand anything; no one explained it to me. Now, almost all the old-timers there have either retired or passed away; one old man died while I was there. And that's how they die, without revealing any secrets about technology or anything else. So, we wander around like idiots, not knowing what tomorrow will bring.

I remember the linear-amplitude frequency response (LAFR). But what is it used for?
