I found your videos on Utube before this here. I think they are very informative, Thank you for sharing. I do have to do a lot of sifting and jumping around for a newb like me. I look forward to seeing a step by step of first things first, " ...After you have all your gear in....etc". Do this, then this, then this, and that.
Something I can follow would be a blessing. None the less this is surely something to add in to other videos to get me started from top to bottom.
Some are doing it while in the car, others NOT in the car...etc.
Also, I have seen people take RTA readings with the zero axis head on narrow angle of the mic, and I seen your ear to ear 90 degree version, and then yet I have heard to take readings of the tweeters in dash from opposite sides of the Car for better results.
(left tweeter, right passenger window/right tweeter, driver window). etc...
Does it make a difference? Why?, and how? and is there a measurable better method?
1) To apply it, watch them in series as they're numbered in order and perform them the same, from crossovers through levels and TA through into individual driver EQ etc etc. These methods are just the method Kyle shows and as he states, there are many methods and orders of events, none really wrong. It's what works for you. The measurements from the mic and your two organic mics (ears) will let you know.
2) There are a gazillion different methods from measuring outside the Car with mic in the headrest, etc etc.. 90 off-axis or point on-axis with the mic. Erin has a vid showing this as a demonstration on taking RTA noise measurements outside the car. Don't sweat the small stuff. If using 90 degrees, try to have a mic with 90 degree calibration file loaded in REW. Measuring inside the car is just easier and takes into account your actual person as part of the "room" which will have an acoustic affect on response.
3) This method is also for a single seat tune, thus he is measuring the averages around one noggin, driver seat. So the mic moving during the averages are done around that noggin. So as thus, it'd make no sense for measurements with mic in any other spots.. be it left or right tweet, mid etc. Measure at your head if tuning to sound perfect at your head.
... In fact, I'd bet, for two-seat tune, if I had to guess, you'd take your measurements head height right between the two head positions for an equal average tune at both head locations. There might be other factors there uniquely measured at each head location, but that might be one method for 2-seat tune.
By the way.. A while back I put all these in a playlist for my own benefit and quick referal. I just found out you can manually order them so I put them in order from top/down 1-12. Starting at the top.. And a 1.. and a 2..
