I want to teach you a foolproof method to get the right
EQ filter shape for your system EQ every time. I learned about this by
first of all using SIM3 because when you are manipulating your EQ in
Compass you can see not only the EQ in SIM3 but you can then also see the
results and then I learned from Merlijn van Veen that you can pretty much do the
same thing in your audio analyzer like Smaart or your SATlive or SysTune
just by measuring your EQ at the same time as you're measuring the
speaker in the room. You remember that in a previous video I also measured
just the EQ by itself while left that connected and what I can do now is just
measure the EQ and basically do a paint-by-numbers
maybe this little tree died and he's naked now, just a skeleton hanging out here
to get the exact shape that I want so for this I can actually turn the
speaker off for a minute so we don't have to listen to it then I'll hit play
on my measurement here turn on the generator
well it looks like I already have some EQ in there from messing around with it
before let's get rid of this
reset my cue all right so the accuse flat how am I
going to side what to EQ well you remember I created my target trace
before so I just put it on top of my optical and mathematical averages here
so I can avoid EQ any comb filtering and now I'll just start looking at the
trends now since I offset my target trace by 4 DB I should probably also
offset this guy so what do I need to do here to my measurements to make it a
little bit more like my target trace so it looks like I have some buildup in
this area but probably more importantly I want to avoid blowing people's ears
out up here around 14 K where I can't even hear it and this low end looks like
it may actually be ending up where I wanted to already okay down here around
30 Hertz this speaker isn't even really playing that much so I may leave this
alone a little bit I may turn it up a couple of dB we'll see so let's start
with this high-end thing that I'm nervous about and then we'll maybe play
with this area a little bit and then maybe bump up the low end all
right now an important part of this is that I want to invert my EQ to my EQ
measurement take a look at that click inverted and
okay and why did it go up okay there we go so I had to change the offset because
it's inverted so let's go to my EQ and let's start making some changes so
probably a high shelf here right and now what I'm going to do is I'm gonna grab
this EQ but I'm actually looking up here alright so basically what I'm doing now
is I'm just drawing up to the peaks of these trends here okay a little too high
okay that'll probably work do I want to put a filter here let's try it looks
like it's gonna meet need to be pretty narrow okay and I'm not going to worry
about this right now because it's just one of those traces okay it's not all of
them and I'm mainly looking at that pink one in there anyway
and then do want to do a little boost here in the low end
maybe so let's give it a shot
you know what I think instead of the low shelf I'm just gonna cut these a little
bit okay because I don't want any low-mid any low build up there so let's
grab this guy there we go
and we can make this faster it doesn't have to be so slow there we go
all right so now I have this drawn in and now I could I could have done it
with the speaker on I just did it off to for my own hearing but now I'm going to
turn the speaker on and we'll be able to turn on the measurement as well and see
our results so let's turn it let's leave the EQ out for a second and now I'm
going to turn the Q back on and we'll see if we start to get some of these
changes that we wanted
okay and now I can just start fine tuning a little bit so I might close
these
just look at the live trace
you
you what I really should do is go back and
measure several points again do my optical and mathematical averaging and
then move forward but when you're working quickly
I think measuring your EQ so that you can just draw the shape on top of it can
not only give you really accurate results but it can also help you be
really fast you don't have to just draw it in wait for the result
draw it in wait for the result I think you can also give you a little bit more
satisfaction of seeing yes okay this is actually the thing that I want alright
so this is one of the easiest most accurate ways that I've learned to
create the right EQ filter shape for your sound system EQ pretty much every
time without making a mistake if you guys have another method I would love to
hear from you you know the more input I get from people the more I can update my
own methods and then I can share them with everybody else
so comment below this video and I'll see you in the next one
