[QUOTE="Ivan Beaver, post: 43546, member: 30"] Re: What (audio related) ebook do you want written? Phase is one of those things that lots of people talk about, but few really understand. Just look at the various Smaart measurements that are posted on the forums. A large number of them are "showing phase", but they have not properly accounted for the "time of flight" to the mic. So it is eirht worthless information-or very hard to read. Yes you may see a "phase issue". But is it the system under test? or the parameters you have set in the program? Or the mic position? Smaart does not (directly) "tell you" what the problem is-only that if you know how to read the phase trace-that there is a problem. The whole "what to do about it" is the HARD part. It is often NOT a simple task. Sure, some examples can be given, but so many situations are different, what 'works" in one case may not in another. It really gets down to a real understanding of the basic physics involved (interactions etc), understanding what the screen (in several different measurements added together) shows you. If somebody tried to write a "if you see this-then do this", there would be hundreds if not thousands of different combinations of possible problems/solutions. It would get confusing real quick. There are so many variables. In reality it is more of "if you see this, then measure/check this-if that is doing this, then also check that. Now go "do" this and see if it changes. If it does, then change this-if not then check this" and so forth and so on. It would be nice if there were a "if you see this do this" type of thing. But having attended a good number of professional seminars etc, with some of the top minds in the industry, and seeing/hearing the often heated arguments over 1: How to measure 2: What parameters to use 3: What the data actually means, really makes it hard to "lay it out" for a "dummy". IT gets real deep real quick. Many people are left in a daze. Case studies are a good thing to start with, but the REAL learning comes from actually doing measurements on lots of different systems, in lots of different places-learing from your mistakes-"playing" with the gear/measurement setups etc. A "dummy" book could be written, but you can only "dumb down" an advanced topic so much. The basic operation is easy-but the understanding of what is on the screen (and what to do about it) is the thing that we are all still learning. [/QUOTE]
