In filter designs, "steepness" pretty much equals "more phase smearing". That's definitely how it works with analog eq designs. If you want to analyze your EQs characteristics, then you should be able to move the phase issues to spots where they are less problematic. I suggest just using your ears to the max though since every design is gonna do something to your phase. Linear phase stuff has issues in the low end caused by lining up the bins, but those issues become less problematic the higher in the spectrum you go. I find mild curves in a standard eq design to be good enough for general tone shaping.

I don't want to quote FabienTDR here without his permission but there's a fresh topic on another forum where he's explaining more precisely how LP filters work and what they do. Topic name is " Linear phase pre-ringing: Does it effect all frequencies?" for anyone interested.
Which section is it under?

A lot of the EQ's perceived tonal quality relates to the way its control laws are mapped.
For example, some EQs not only boost a specific range but would add overall gain. Parametric EQs may or may not have gain/Q compensation. Starting Q values are different. Gain ranges are different—all that even not considering saturation.

I'm just reading a topic on gears**** (forbidden word! ;) ) and it seems that pre-ringing can be avoided in certain cases. It all depends on what filter, what frequency and what signal is processed.

This could explain why in my test I couldn't hear it.

Fabien from TDR is of course the best knowledge compendium in that matter :)
Avoided =! below significant audible threshold. If you use gentle filtering and restrained gain then of course, it will ring less - but in that case, there would also be much less phase distortion with a minimal phase EQ.
It's pretty corelated.
Neither phase distortion nor pre-ringing is extra-problematic when using 6dB/8ve filters and +/-3dB gain.
When you start doing 24dB and 12dB +/- you get either peaks and smearing, or audible preringing.
Yes, i could be more specific. It can be avoided in the sense you can use it in ways that the prering will not be noticable.

1) You need to check you're not using Precise + nor Insane + as those do introduce saturation. Use Precise, Insane or even Eco.

2) TDR NOVA uses oversampling to reduce Aliasing for the entire plugin, and this results in a slightly darker sound.
Why would oversampling create a darker sound?

Does nova have per band saturation?

I'll take a guess here. The aliased harmonics above nyquist fold back from the top frequency, not the bottom, so that puts more weight at the higher end of the frequency spectrum, in general.

With oversampling, ideally, you would eliminate that harmonic foldback for a cleaner sound that, maybe, subjectively would sound darker to someone.

eq filters are compressors. some eq's allow you to control the compression of the filter. linear phase means all the filters compress at the same time, in an rms style.

I just learnt something new here. I thought EQs were just frequency dependent volume controls.

Indeed. Not even an analogue one.

good chance you have better speakers then me at this point, I've down graded over the years as I've become less important, but this is my personal fav. https://lvcaudio.com/plugins/toned-max/

the blessing and the curse of digital is dead space. absolute silence. before computers the only place in the universe silence existed was in a vacuum. that doesn't make digital better, it makes it less musical imo. I own 60 minute cds i bough that are 3 decibels above silence. we were experimenting with the that new space called silence. silence is boring. noise is musical.

there are a few imbedded pieces of advice from famous respected musicians that I hold onto.

1: digital is too clean, and gives your mind no where for interpretation and imagination.

2: when you meet someone who is enthused by sound, it's the quiet sounds they are enthused by.

Post

The best advice anyone can get is, whoever you listen to, please don't listen to arguments like those Dasheesh is making, because they cheapen discourse and add nothing of substance to the conversation.

Also, EQ filters are not a compressor lol
I don't know what to write here that won't be censored, as I can only speak in profanity.

The original "ah ha!" moment for me was when I realised EQs actually use phase shift + phase cancellation to perform said "frequency dependent" gain changes. That kinda blew my mind when it first dawned on me.

EQs are compressors? Oh boy....

if you have one good preamp emulation you can use one or 2 with a clean eq in the middle , it should give you a more "similar" sound to some hardware eq. don t apply much gain if any at all on preamps , depend the color after but it its just for the transformers , opamps ect emulation, you can have clean eq that sound as sweet as nebula like this
