hm yes that sounds logic, thanx for your reply.
or could it also be that the waves eq has just an grubby algorithm or something like that? |

Well, looking at those two pics makes it a pretty obvious fix. Just bring the slider down (with the hi-pass on) until you bring it back to the level you want it peaking at.
You also have the filter's gain maxed out. You can bring that down a bit too.
Peace,

hehe yes i know, i just wondered why this is so...
and the gain of the first slider is irrelevant when it is switched to 'high-pass' mode, that's a feature of the renaissance eq (i always put the high/low-pass sliders above cause i like the view)
but anyway thx for the replies. |

If I've got this wrong I'm sure someone will correct me, but I think that's how it goes

I don't think the signal has cancelled frequencies when it enters the eq. Instead it could be other way around:
because of phasing two frequencies could build up. Same with if you all-pass filter a sawtooth or pulse wave. The resulting wave doesn't peak that much even though it contains all the frequencies as the original one and even sound pretty much the same. Do same backwards and there you have it.
But because we're talking an analog (modelled) eq here, there might be some kind of harmonic distortion or similar going on.
Seamoon, have you tried A/B:ing the signal with spectral analyzer? |

it doesnt sounds right to me... if the bass is singel oscilator so how can it cancel itself?
I think its about energy shift. if your wave is 0db and you highpass low freq - than some higher frequincies shift higher and clip.
If you "peak" -18Db down it doesnt makes it.
think about it as if you got some amount of energy / voltage that produce your sound. when you highpass - that same amount of energy produce less frequiencies (also very low freq` are harder to produce) and "push" you signal higher!

I think shacar is right, I mean if the eq is an analog modeled eq to function like analog equipment would.
Then when you remove the low frequencies that are hard to produce all that power that was pushing that low end will now be transfered to the rest of the frequencies, pushing them with energy freed up from the low end. Essentially boosting the volume of the sound as soon as you turn it on.

well i have no answer but defintly have same issue here...
specialy with high pass on bass , sometimes it gets +3 db
simple solution with bass in to not hipass and win your 3db , either lower the volume if hipass made it realy sound louder.
i would think it got defintly something to do with resonance , not Q like in waves Req , like older style filter that usualy push up the level of the same frequency u make the cut (150hz in your snare picture) possibly this resonance is the real problem , solve it with more hipass usualy will work , if it gets too thin , then simply lower the volume is what i would do.

Colin OOOD could be right but there are more than one thing that could cause this "problem". What he explained is a well know issue.
It could also be that the filter starts to "wave", wich are not shown in the EQ curve. I dont know the scientific reason for this.
Or as someone explained (or not?) many analog filters have a boost right before the knee of a highpass/lowpass filter.
I think its a combination of all three actually.
Your slope is also really step wich definelty will make it wave. |
