Rolling off bass freqs?

[MARKEG]

i totallly stick by what i said ;)

I guess there is no real rule.
essentially the roll off depends totally on where your bass sits.
I tend to do it by ear, but it generally sits from 40 - 80
if you got no low sub then you can roll high, if you got real deep shit, then go low, but no lower than 40 if it`s for vinyl

What do you mean by "rolling off the bass" ?

[acidsaturation]

It totally depends on the use of bass really
I`m doing a lot of stuff with real big dub sub, and the roll off is a lot lower, but then, there`s less going on in the mix so there is more room

Interesting you say that - 'cos I've been playing with this from trial and error having been told so many conflicting views - and starting to find that. Busier tracks need the bass rolled off higher to get them louder and less messy but where there's less going on you can fit more sub. Makes sense if you think about it I guess, but it's another of those things that you never realise till you mess around...

What do you mean by "rolling off the bass" ?

It's referring to the slope of the hi-pass filter/eq.

I captured a pic in cubase cause i really want to understand this....



Would that be what slopping off is?

[loopdon]

yes.

[nova]

so thats 58hz yeah??. so thats slopped at about 60 pretty much??. and i tak thats a channel eq?. also would you guys get a nicly eq'd kick then start fitting bass in with eq and then go from there??. would bass sit under around 40hz?? if kick was at 60.

On the cutting bass frequencies problem ... it's cool if cutting engineers do that for you but most stuff we do goes out as mp3s to djs first now so it's worth doing something about the bass ... here's my thoughts anyway.

You can avoid putting bass roll off over the entire track by treating the kick and the bass seperately if nothing else too bassy is going on in the track.

It's important to ditch the very very low frequencies while you are working, particuarly if you are compressing the entire track (compress after the filter). I'd do that with a 18db/oct filter at about 40 Hz (about the freqency of a low E on the electric bass) which is about the lowest frequency you'll get out of a lot of sound systems. You shouldn't be able to hear the filter come in on most monitoring systems either, if you can hear it it's probalby too high.

If you are using analogue synths for hte bass its' a good trick to work out what the fundametal freqency of hte lowest note is and filter everything just below this as some analogue sysths wack out all kinds of weird things in the sub end below the main tone. Most modeling digital synths are ok without being treated like this though, certainly the ones i've tried are ok unles you wack the resonance right up.

If you keep this extra low sub energy in then you'll find on some systems you are just driving the amps to produce an inaudiable sound and your track will sound quiet.

The danger is if you cut too high that you'll lose some of the warmth, if this happens try a 12db filter instead or cut at a slightly lower frequency.

After that it's a matter of taste if you choose to use a low shelving filter as well, if you use the EQ curve in that picture you'll get a 'tightening' of the sound as the bass drops off and lose the warmth ...

good read ;)

Good call Basil
