"nope, how i can tell you.. i can cut the high by myself,
so
yes, mid/bass is where i want the work done. is this of any
relevance to the headphone.speaker calibration issue? "


this is in relating to your speaker within your room, yes.

i mean, there is also difference in the high frequency range
from headphones to speakers and in the room itself
geographically but that's a fun part to play with, the
melack way (listening both on the headphones and speakers
and discovering new tones by trying to collimate)

this owuld be an example of the 'reflection
points' in a 5.1 setup

much is different. are you mixing or are you just
listening?

the both of them! thanks for sharing, all is incredibly
understandable. not easy to go though posts like that. i had
to cut a bit where i didn't understand for lack of
experience, hopefully this thread gets me ears where they
want to. give me some time to measure, hopefully not years.

anyway the eq method is ideally right, for a fixed point in
a reflection-free space

install room eq wizard
statically setup your mic at the listening position
run ETC (0-300ms resolution)
run waterfall plot (0-300hz, 0-1000ms)
run frequency response (no smoothing)

and upload

generally, absorbing (or redirecting) the early reflection
points will solve most of the issues in the room regarding
specular energy (e.g. sound that functions like a ray).
500-20khz, depending on room dimensions.

below that, the bass/low freq modal region... well. that
will take a lot more effort.

told ya that for the bass you have to be realistic

"told ya that for the bass you have to be realistic"

there are inexpensive, DIY solutions. it will take up some
real estate in your room, though! but very realistic and
quite an easy task.

all this is nonsense until we have measurements.

i know exactly what you mean, clear specs are needed to get
the job done. i'll have to buy the mic first yo, these days
i have tons of shit in my mind to manage that i use all
'energy' to stay ok. priorities :)

about your second link,
has anyone recommended using a spectral view?

to use while doing music? i don't think anyone suggested to
use it 'real-time' yet, otherwise yes, peeps have suggested
the use of it to be able to permorm calibration and
measurement tasks

I freqy sweep speakers vol 95 % then eliminating audio
inperfections with EQ.

i'll have to calibrate the levels in which i do my crap,
too

the levels between the devices

with the heaphones, making shit that sounds low, with the
volume of the computer maxed out, is just stupid. i always
forgot to work at medium, 3/4 of volume for more balanced
tunes

same shit for the speakers. with the computer volume at max,
i keep turning the levels down and down to keep making for
hours without being noticed by the neighbours. makes it that
the music almost vanishes

just for a start

what does that even mean.

nightex may mean : sweep a sine wave with amp volume at 95 %
and flatten with an eq.

Points: 31145 Status: Regular | Show recordbag



what do you mean by flatten in stupid-proff words?

i might need that sine wave to calibrate the level of the
speakers, since i don't have a numerical value to set their
volume. not the level of the computer, the one of the actual
speakers. luckily the sub has a knob behind it that i always
keep in the middle. but the speakers have two little metal
plates with a + and a - on them with some sensors on the
inside i suppose. i want to set that exactly in the middle,
same of computer level. they're always maxed out cos after
all these years they suck a bit, sometimes they low down by
themselves and i have to push the + sensor a lot before
sound comes again.

does that make any sense for 'flat response'?

i'll check you out elusive

i still hear a lot of difference from the headphones to
speakers, while listening to my own shit at least. i suspect
that those motherfuckers are just good to 'measure'
pressure, and but unreliable for all the rest. the room
makes a important role in the negative, as well. too
different. thus the need to start there, to give some layer
of medium-bass and refinishing it later on headphones. i
have some extra cash for the mic this month, it's mostly
lazyness. i hate to look for equipment shit.

beart with me

how do people out of the loudness war record their shit?

There's tons of dynamic range to be played with, by
balancing perceptive loudness with actual dB levels. I'm
totally against the loudness wars and want to jumpkick every
inconsiderate and tone deaf motherfucker who makes overly
multiband-compressed fucking bullshit, but at the same time,
my tracks tend to be pretty "loud" due to balance with how
sound is perceived.

Again to those who think they're fucking Daft Punk Dub Step
Clark flat bullshit fuck: Fucking learn how to hear you
fucking asshole- your music is shit and your skillz are
shit, and if I see you in person I will serve you so hard
with my choonz, you sonovabitch-- your momma- in hell or
not- is gonna think you're a fucking lobster cuz you smell
like fried cunt, you lame ass hipster wannabe musical
fucking wanker with no sense of style or subtlety fuck. How
about you put your ears in a blender and maybe you'll
actually be able to feel something that isn't garbage, and
maybe you should spend your time learning how to play an
instrument "or something", instead of hiding behind some
sense of oddity and abstraction to cover up your lack of
aesthetics. Fuck you- you're not helping anyone and not
even yourself. You notice how easy it is to make your
fucking bullshit? It's not because you're good- it's
because you suck so hard, you make my momma look like an
amateur.

AAANYWAY---

For example, super-flat compressed parts can be turned waaay
down and still be perceived as loud, which leaves room for
pop for the parts that actually do need to kick. Also
enhancing the "voice" freq in music tracks (most audible),
allows those tracks to be turned down as well- again-
leaving tons of air for the parts that actually should be
explosive and liquid to give a sense of WHOA. Electronic
music tends to have a problem with trying to actually
recreate sounds, instead of giving a relative sense of them.
Like if they sample a gunshot, it's like they're trying to
fucking blow your ears. Listen to 80's Michael Jackson and
turn up the volume, a

thanks for the explanation. i used to know what compressors
do but nowadays i just stick a compressor preset called
'analog tape compressor', when i hear that preset pads are
too high already. and just cos it's called that way
