...just mastering a track, it sounds pretty cool, I ve cheked on many environments. As this is a loud dance track, I have quite strong representation of all frequency range. NOW.

Regarding to PAZ frequency analyzer-meter, of course there is some energy left ABOVE 20kHz, now I wonder if I should use Linear ph. EQ to "get rid of those" as this is a mastered track now.

I mean, how it is the situation with this critical frequency energy?

Hope you know what Im talking about:)

Why would you want to get rid of that?

I mean, you aren't going to hear it anyways, but throwing a brickwall up to kill this may alias the sounds below it. Not that you'd probably even hear the range in which it is aliasing as well (what is it? a new born baby with his ears cleaned can hear up to 23khz? Where as the average human is MUCH lower -- even if most engineer claim to be able to hear above 20khz, they are pretty much simply hearing artifacts from bad ADDA converters in which carry specific audible characteristics).

Does it sound right? If so, it is right. Don't use visual cues except when it doesn't sound right -- and then learn to get the right sound by ear so you can ditch these

My first thought is, have you looked at other mastered releases (of similar musical style and sound) through the PAZ meter? That would give you a better idea of what it should, or better yet, could look like.

There's a lot of important information up past 20K. Not so much as to anything most of us hear directly, but what it does to the overall sound... indirectly.

Go with what sounds good to you, but do look at some commercially mastered mixes, as well as listen to them, to help guide your decision.

Clif, muchos grazias:) I am lucky achieving decent production, still, often want some "theoretical" background - details that are sometimes hard to find around.


BTW, I found analyzers like Logic 7's or inspektor pretty poor...

In most cases in this "roof" over 20Khz are hiden so many important things like coloring of the sound, air etc...Usually it makes the sound bigger and the stereo more open - of course you need a good equipment/monitoring for a right sound judgement.Regulary when I like to ajust the mix/mastering very fine for this "roof", I use my Sennheiser HD 600 Avantgarde headphones /12-38000 Hhz/. There is another model /Orpheus with range 7 - 100 000khz/.That's why the companyes produce this Hi-End equipment for controlling this "invisible" ranges, it is very important!

Jim F's comments, as usual, are bang-on. While most of us may not be able to hear frequency detail much above 20KHz, we can certainly feel the effect of it. The whole upper overtone structure of sounds you CAN hear lives up there.. filter those overtones out, and it's definitely going to effect what you can hear. That was one of the reasons (there were numerous ones) for the lack of a more pleasing sound in the earliest digital systems.. because all of that detail was brick-walled out since designers thought "no one can hear it, so let's get rid of it." Love the overtone structure of your audio.. embrace the overtones. They're your friends.

Cheers.
