What does Flat Earth mean in audio circles?

Why is it not surprising that it took a man of your username to set the rest of us straight on this issue? :-) I personally never use the term 'PRAT', and now I know why I don't use 'Flat Earther' either...and why a guy who writes about 'getting notes and beats right' does.

Just a little sidenote-
At the same time that "The Flat Response" was publishing in the UK, another small audio publication with a very similar "Flat Earth" focus and attitude began it's own brief but influential run in North America.
That magazine was called "HiFi Heretic" and its contributing editor was a gentleman by the name of Art Dudley. Music reviews were handled by a young punk rocker named Rob Doorack.

Just a little side note...

First Earth is not flat nor it is perfectly round. Its elliptical.

Flat Earth is an approximation because over a small area(surface area). The surface of the earth may appear flat, since the "bending" of the surface is very hard to detect over small distances.

What does any of this has to do with audio?? Not a damn thing but I was bored and I figured I'd amuse you all...

Have a good day

I'm not amused.

Ffontan...Actually, not elliptical. It's an "oblate spheroid" with many anomalies. (We get into this in the field of balistic missile guidance). And the shape changes several inches during the day.."land tide", and thermal effects. This science is almost as complex as audio.
