Low/Hi Pass Filter on the MasterBus?

[open mind]

i read somewhere that most speakers and average human ears cant recognize frequencies under 50hz and frequencies above 20khz.so what do u think about putting a low/hipass filter on the masterbus?

is that a common technic? would be nice to hear some opinions from Students,Master Engineers or Pros in the game.thanks in advance.

 

[open mind]

yeah would be nice to hear what wings thinks of this.iam sure he can help us.

whenever you're using 808s or sub bass bass or kicks in your beat, you should definitely be using a low cut eq below 37 hz or so on those channels, which will eliminate most of the muddiness as is. as for the master channel im not positive but I imagine a low shelf around 20 could work, sure.

also that 50hz info is wrong...808s are 45hz fades, and its why it has that notorious trunk rattling rumble, because its getitng close to as low as we can hear.

generally hipasses and pass filters aren't the ideal things to use where you need absolute precision- remember, pass filters not only have resonance but cut based on slope, so even if you set a -24db/oct slope it is still a little sloppy with the signal. when you eq using a low shelf/cut, you will be knocking out EXACTLY from 37hz (or wherever) on down, without touching 38hz. not many filters have that precision, and its more steps to set it to do the same thing.

yo open mind i am glad you brought this up becuase i would like to see a discussion on filter techniques low end theory ect....

something that wings could enlighten us on threw educating artical or something


just a thought

what exactly do you want to know about filters?

by the way the whole low end theory thing is a little overblown if you ask me. i see people on future producers talk about it like its a magical process...the only thing it does is make your low frequencies louder, nothing else. since you're doubling the track but only keeping the low end of the copy, its just making the bass louder when mixed back in. i guess thats cool but you can eq to do the same thing, and prsonally i think a properly applied multiband compressor can do the same thing even better. a multiband comp can actually make the drums thump harder instead of just being louder. it also depends on what type of production you do...if you do the old school boom bap stuff low end still has its place but you don't see as many producers who do new hip hop doing it now.

Hi/Low pass filter on the Master fader is generally a bad idea.

Like my man hilo said, u want a low shelf to cut the lower portion of the audio. maybe 40hz and under. and with a medium bandwith curve (q)

 

[TheDeen]

It's 20Hz to 20,000Hz

I make my music for more than just mere humans.. I do all types of enhancing in the other frequencies, for "The others"..
Good thread tho..carry on!!

Check the EQ:

If you need to cut the lows do it on the individual tracks, leave the master alone.

good looks fam. iam just wondering why is a shelving hi/low more precise then a hi/low pass?
thats new to me.thats waht u sayin right?

 

[breal]

The only time where putting a lowpass filter on a masterbus is done is when a
producer is making a techno type track and they do a filter sweep.

ok... because a hipass filter allows only frequencies HIgher than what u select to be played, and does not cut or boost certain frequencies, it just blocks them out completely, and u cant really set how wide ur scope is... the closest thing to being a real EQ is the resonance knob.

Lowpass filter is the same but it only allows freqs lower than you select to pass thru.

as you can see, you will be cutting off large chunks of sound doing this on the master fader. (even if u try to cut below 20hz.. it will probably come out sounding subtly thin)

a low shelf allows you to cut, or boost, frequencies below the selected region, and the bandwith knob allows you to set how wide or narrow the scope is for ur cut/boost. as in, if u go to 20hz, with a narrow scope u will be only cutting/boosting 20hz and its very close relatives.. a wide scope u can probably catch 0hz-40hz.

what am i doin.. fade posted teh link... read that

Actually Sanova thanks ,that explained it better to me..

GOD DAMN IT NOVA! read the fuckin topic. lol. the link from fade is about eq in general.

i wanna know if that is a common technic to cut under 50hz and above 20khz not general eq and proposes of diffrent freqs thats a hole diffrent topic!!! that been said i wanna say thanks for the explanation of the differences between shelving/pass filters.


this is straight about filters in the MASTERBUS not about general EQ just wanna clear it out.

 

[Sanova]

yeah if possible post that link and basically real qwick you say low or high shelve filter to nip and tuk frequencies on the master Fader ?

EDIT: hold up.. i posted too soon, didn't even know there was a second page lol lemem read this

Well if you know what they both do.. then, it should make the answer to ur question clear.

and the answer is that filters on the master fader are usually a bad idea.

Oh yea.. come at me like that again and I'll have you blackballed to where you wont get another good review in the showcase... oh, thats already happened? lol nah but seriously relax tho..

But anyway YOU read the fuckin topic. yo uwill see that I have answered the original question TWICE now... AND the info I posted was obviously helpful, and was in response to something else.

So, again... don't come sidways at me like that when i'm tryna help.. Im not the one.

First of all, undamaged human hearing is 20hz-20khz. Although I'm more than certain that each and every one of you have hearing damage and can't hear all of that, the 20-20,000hz is the rule of thumb

I would never put a filter on the master fader unless it was automated for a desired effect. But for general mixes I don't put anything on the master fader. If you get your mix right, the master is really just your level meter and used for fade outs etc. For various project's if requested we use hardware on the master output. Diddy's album for example. I can't remember exactly what pieces we used but it was an EQ and compressor. Very light compression, basically used more for the warmth of the gear. Very light EQing as well. Mix the individual tracks, not the master.

Also, in my case, everything we mix usually ends up going to mastering. So our job is to just get the mix sounding as good as possible, the let mastering worry about any overal changes, which are very minor in most cases if the mix itself sounds right.

Also, if you cut out frequencies, you're losing the inaudible harmonics. Even let's say if you cut everything above 20khz, even though your ears can't hear those frequencies, your body can still feel them. Those harmonics can be important to the feel of a record
