Aha, I have investigated this issue and think it is of 'usage' nature.  Actually, example you have sent me has a too steep curve transition.  In such cases pre-echoing is most hearable.  If you make transition more wider, pre-echoing will be minimal.  Even if other EQ plug-ins do not produce pre-echoing, they also cannot perform EQing with quality CurveEQ has.  Also, they cannot have curves of any complexity.

So, I guess, this is not an issue of CurveEQ itself, this is rather a question of usage.  But I'll keep this 'pre-echo' issue on my 'todo' list, however it is not of the utmost importance.

Cheers,

Aleksey.


thanks for your work, but for me its very important cause i do such hard modifications very often and so it makes no sense to use voxengo curve eq with it as you could hear. but as i see there seems to be no way around if i want linear phase, right? but i guess i rather switch back to Waves Renaissance EQ for that kind of stuff then. big thanks anyway.

ah and btw, the quote "they also cannot perform EQing with quality CurveEQ has." is not realy true, i sometimes prefer, and others do as well (just if you remember the Pultec EQ) the old "analog" style eq sound that adds its own live to the sound. and as i can see Curve EQ is also very much after this with its "Gear" emulations and the Saturator.  So its not always the "clean and super" sound people want, as you dont want it too it looks.

have a nice day.

Does that mean, presets like "Steep low-pass filter" and "Steep high-pass filter"

will also produce hearable pre echoes ??

Yes, actually, these presets produce 'windy' sound.  That's the effect of pre-echoing.  I personally don't dislike it, but someone might say it hurts.  I'm reading about minimum-phase FIR filters now which might work as 'no pre-echo' alternative.

Hmm ...

Are these echoes always generated, even when continous signal is present ??

In other words, are they continously added to the original signal ??

( I have to say, ´till now, i haven´t experienced any pre echoes. )

bye, Jan


Yes, of course.  But pre-echoing can't be easily heard on continuous sound.  It is objectionable on transients only.  That's the nature of linear-phase filters since they work that way.

then we should forget about linear phase filters, as they make the sound muddy and wash out drum tracks as they have high transients.

i would rather accept an non-linear phase but not this pre-echos.

Guest, that's a subjective thing.  Some like linear-phase, some don't.  You don't.  But I'm working on making zero pre-echo filters as an option.  That might be usable.
