what exactly is "Computer based RTAs"... or hell.. RTA's.
An RTA is a Real-Time Analyzer. Car and Home audio people use them to measure the way sound waves are affected by a room, or the interior of a car. This measurment alows us to adjust for any peaks and dips in the sound waves giving us a flat responce. In other words, it alows our stereos to replay the music the way the author intended it to be heard.
You can also use it to set your x over points and slope, help you to decide what size sub enclosure to use in a car, and so on.

That is a real basic rundown of how to scan your car. Its basically the same thing the newer Eclipse and Alpine decks do, but they aren't as acurate, or detailed.
