[QUOTE="Ivan Beaver, post: 96374, member: 30"] Re: Sim VS Smaart And that SPECIFICALLY address the whole "What am I here to do" question. If you are wanting to measure the response of the speaker-then you want as little of "the room" to get into your measurement. An area where TEF excels due to its noise immunity. However if you are wanting to "tune a system" for people to listen to-then you have to allow some of the room to get into the measurement (how much depends on the hearing mechanism). So if some of the room is getting into the measurement-then you have determine what is important to address at THAT mic position-since it will be different at a different mic position. The more "room" you allow in-the more important it is to do multiple mic positions and average the results-so you don't "fix" one location and screw up many other with the same adjustment. If you want to "adjust the response of the loudspeaker" and then let the responses "fall where they may", then you want as little of the room influence as possible. Personally I find I get better overall results by allowing some of the room to get into the measurement (relates to my ears better)-and by using multiple mic positions, paying attention to dips in the response and what the phase looks like at those dips- helps me to choose what to ignore and what I can "fix" with eq. When people start "chasing" all the dips with an eq-they are asking for trouble overall-because they are not taking into account reflections-one of the MAIN problems with using and RTA to attempt to align a system. And one thing that I feel is very often overlooked-there is no "correct" alignment. Let's say I align a system. Then I come back a month later and do another alignment-after the DSP has been reset to 0. Will I end up with the same results-NO. Will they be pretty close-or very close? I hope so. But depending on my new mic positions-how I feel that day (especially when setting delays for balconies and so forth) the final result will be slightly different. How much low freq "hump" did I allow this time? How about HF rolloff? What about delays? Which one is "right"-both are-AT THE TIME I WAS THERE. When you deal with multiple sources and multiple listening positions-there are all sorts of compromises that have to be made-and on any given day I may choose to make a different compromise. In my opinion-anybody who says they do "perfect alignments" is simply fooling themselves and attempting to fool others as well. Just like mixing a band. Create a mix-lets say from a multitrack so the source doesn't vary. Now come back a couple of days later and start with a 0 console. Let's see if you create exactly the same mix. A good engineer should be close-but if you store the scenes on a digital console and recall them-I bet they will sound different. So which one is "right"? The biggest thing to learn with system alignments (and mixing) is when to stop adjusting and say "this is good enough". Flame suit on. [/QUOTE]
