problem with low freqs on synth lines

hey guys,

i have noticed the following problem:
For my Synth-Lines i always add first an EQ with lowcut about 300hz and highcut about 5kHz, after that i always add a limiter (L1 from waves).
Now the problem is the eq eleminates all the low freq very well, but trough the limiting process there will add some very low freqs again.

do you know how i can solve this??

wehen i put the limiter first and then the eq it cut all low freqs very well but then the peaks start getting out of controll.

Any tipps??

Lowpassing at 5Khz? Isn't that a bit too much?

As for your question, how about doing the highpass, then limiting & then doing another highpass.

turn down the volume of your synth till it doesnt peak anymore without any effects on it, and then add the eq (but I would do the higpass a bit lower and the lowpass much higher)

if your sound still needs limiting, try what get-a-fix said...but I would always keep an eye on clipping at the channels (also between the inserts in the signalchain), cause what is lost, is lost           https://soundcloud.com/hazak

hmmm i use the limiter to reduce the dynamic (very carefully, just reduce the peaks about 1-4db) but even when the limiter just reduce the signal abut 1db, there are often add low freqs.

when i first cut the lows, then limit and then cut the lows again, there will add peaks again and so i don't have full controll over the dynamic.

the same effect i get when i use compression instead of limiting..


ps: i don't mean i always add the limiter directly after the eq, often the chain is eq -> fx like chourus, flnger,phaser and then the limiter in the end, or first the fx then the eq and then he limiter.

pps: where do you cut your synth lines?
for me its like this: synth-leads, pads and atmos i have between about 200hz till 6khz and my percussion i put above them.

did you try to lower the output of the synth?

do you use a limiter on every channel? I would just use is if its really needed...

when you cut your elements that high, you sound gets pretty thin and you lose important parts of the frequency range...I usually cut everything btw 160 and 500hz (with a few exceptions like the bassline or few fx samples) but I work a lot with shelving...this helps a lot to take a bit of lowfreqs out of the sounds without cutting them totally, so your sounds stays warmer and doesnt get so thin           https://soundcloud.com/hazak

why not use a compressor for that?

Hi,
try to use spectrum analysers and you will see that your hi-pass (low-cut) aren't really low-cut or hi-pass=)
By the way, the result depends very much on EQ plugin you use.
For example i've made two screenshots of how different Waves Q1 and Voxengo GlissEQ work, with the same settings (200 Hz hi-pass)
Q1 - http://amulet-spb.ru/wavesq1.jpg
glissEQ - http://amulet-spb.ru/glisseq.jpg
However, you can see that low-freqs always stay there, and certanly they grow up again when you use L1 and become listenable.           http://soundcloud.com/aedem

please please use higher cut for your leads if u dont search for special low-fi effect
what filter so you use? 12/18/24 might sometimes be not enough and better to cut twice with 36db filter to get super clean signal

i will try lowering the volium of the synth, maybe that helps...

i always use the waves Q series with two lowcuts(what are they 12db/Oct ?), sometimes more, and for the high cut mostly just one
(of course the the high is not always exactly at 5khz, that depends on the synth ofcourse).

But maybe i'm a bit too paranoid about my peaks...

thanxs for your help guys!!

I use Waves Qx with up to six low-cuts at the same frequency.

The low frequencies you see after your limiter are the result of the limiting action varying the level of the track. The specific frequencies are related to how often the limiting action occurs. You'll get this with any compressor I think, it's a 'laws of physics' thing.           Mastering - http://mastering.OOOD.net :: www.is.gd/mastering

maybe it s distortion ? i never had probleme like this even with bassline, maybe tweak your synths so they don t have all that bass.
can you ear it or you see it on a spectrum? if you don t ear it s not a problem.

Colin can you elaborate on this ?

You can think of compression as a form of AM - the amplitude of the signal is being modulated by the compressor as it reacts to the dynamics of the sound passing through it. AM produces sidebands - additional frequencies related to both the audio being processed and to the frequency[ies] by which it is being modulated. These sidebands appear both higher and lower in the spectrum than the original signal, and it's the lower sideband that is most obvious in your situation as you've high-passed the original signal, leaving the space free for the lower sideband to be visible on its own.
