Do we crave distortion?

Ok, understand that in practice equalization is under Nuquist requirements so don’t need infinite accuracy. Then the information lost is under audible threshold or at least is lower than the perturbation to the signal added by room modes and reflections…

But some time ago a member gave some advices to equalization: under 400 Hz, only 0 to -6 dB and Q factor <= 5

Is this based more in acoustics than in digital analysis of the signal?
Equalization (if needed) is gear and room oriented. With Shannon--Nyquist you always get the perfect data required to perfectly recreate the signal you want to capture.

PEQ is about coming as close to that in your room, with your equipment. Personally I don't use EQ. I use measuring equipment to position stuff as best as I can in my environment (and I have had the luxury to pick good environments).

My apartment has good acoustics: in the sense I can listen with perfect pitch reproduction noise from my neighbors :)

But unfortunately we suffer both from rhinitis at home, so we have no carpets or curtains, fabrics are limited to the minimum… all is reflective at home.

By ear I’m satisfied with just correcting a couple of modes, and the crossover region of my Genelecs (2 way monitors place vertically, has a moderate 2-3 dB dip on 2-3 kHz).

What do we call room modes? Distortion? :) And we enjoy our music nevertheless right? And we did way before this quest for more utter accuracy started... :)

Not in my case, the low ends eats melody and is fatiguing to me. I prefer to equalize and enjoy more the music. One of the modes is nearly 9 dB, so the frequencies there are perceived twice as loud as other frequencies.

I don’t compensate all those 8-9 dB, with 5 or so I’m happy. In many classical styles, also when I monitor my own interpretations, twice the volume changes mood of the music.

Personally I find EQ a good thing if doing on important regions and not by chasing perfection, so that room response is not aggressing the music.

Of course many concerts out of a well treated concert hall or theater have room responses, echo, reverberation… I listened to many concerts in churches and I admire the organist to deal with time delays from the tubes and more than 5 seconds of echoes…
 
I repeat there's plenty of classical music with distortion around. Listen to Matthew Herbert's "Mahler" on Deutsche Grammophon. It's horrific but basically it is an ode to distortion, among other things. Clipping, crossover, slewing... to the max. On purpose, which if you listen to Matthew Herbert regularly is zero surprise. I hate it. :)

For example, go to 5:50 here:

Plus the person asking me to start my own thread is not the OP, so he can protest all he wants and see how much I care. This *is* a topic on distortion and whether we like it, says so in the title (without any reference to any H). :)

PS: It was claimed in the album notes all the effects were created by distortion of classical music passages and recording in weird places (including a casket) with weird techniques. In other places, of course, I actually find distortion can add pleasing effects, Max Richter uses it masterfully in many of his classic-newage compositions and albums like his Vivaldi interpretation.
Obviously you can post what you like up to the pont that the moderators allow.

My point was @Keith_W was adding H2.
The suggesting that an orchestra is distortion sound may be interesting, but I do not think that the musicians are adding harmonics.
Gawd only knows what mixing engineers are doing.

Threads often straw away from OP’s intent, and often in interesting ways.
Try not to take my knee-jerk (or third derivative of keen angle), as a mandate to start your own thread.
It is just that the orchestra seems to have no bearing on someone, or some mixing person, using H2 like a Chinese restaurant uses MSG to improve the taste.


Surely should be easy to do on the frequency space, just adding A(2*f) + B(3*f) choosing coefficients of the amplitude as desired in proportion to original amplitude of fundamental
When walking teh dog last night I figured that ^that^ is how a dummy (like me) would do it :rolleyes:
But then I wondered about C being positive or negative?

Your idea of Chinese food is the wrong way round. Chinese restaurants do not use MSG to improve the taste of food. Chinese restaurants use food to improve the eating experience of MSG. Because eating a bowl of MSG by itself isn't very nice, it needs some food in it.

I should know. I'm Chinese.

Irregardless of the truth, it seemed like the lore fit in well with idea of the H2.

We went to a place in Freo call Emily Taylor’s a couple of weeks ago and the dragons were parading around for the C’NY.
I expect Melbourne would be next-level.

Where in Melbourne are you?

If MSG is mono sodium glutamate (or something like that) then are a lot of restaurants that add it, Chinese or other nationalities…

I lived in Paris two years, I remember a journalist who published a study where showed that 5 of 7 restaurants with menu under 60€ /customer used prepared food cooked on microwave oven and just added some personal sauce and spices.

And of course MSG was ubiquitous…

Restaurants admitted using prepared food (in the “capital of French cuisine” ) argued that location were so expensive at town center that they had not money to afford a proper kitchen (some let journalists film the inside, were little rooms with 4 or 5 microwaves ovens) and assistants to cook authentic handmade food…

When I went through college I washed dishes at a Chinese restaurant to make my way and part of my job was refilling the large tubs and barrels of supplies in the kitchen. The kitchen consumed about 30 pounds of MSG per 3 or 4 months. Tiny quantities in some dishes but not all.

Here in Europe is mandatory to declare dishes with MSG since 2018, but we discussed the “MSG syndrome” with our GE specialist at the clinic and told us is a myth… studies shown that people suffering symptoms were undergo blind trials and shown symptoms with placebo as strong as with MSG

Apparently is totally safe in ordinary quantities, only dangerous in absurd proportions impossible to ingest as flavor additive.

It was originally used in Japanese food (extracted from an algae and mixed with sodium) and considered delicious …

I think Pablolie was talking about effects added on the recordings, some videos he shown were horrendous… but were “clean” in the sense of the album shown that added harmonics and effects.

I don’t think violins scratching or other non-electronic effects in classical orchestras has anything to do with harmonics, more than noise and kicks when grasping the strings or hitting the wood.

Do you agree with the advice to just use subtle EQ to correct a couple of modes or you prefer total room corrections as DIRAC or GLM do?

Nothing to do with the topic, I will open a thread to get help on that but I’m interested since I’m also dummy in PEQ, I purchased a WilM Ultra but the algorithm of room corrections is crazy and prefer just using the filters by reference to choose my own corrections.
 
...

That I disagree with, sorry. Any instrument sounds the way it really does because of harmonics, and because those are captured in the recording.

This topic now seems confused about what the definition of distortions vs harmonics is. It's about distortion (which comes in several forms). Then goes to claim it's about 2nd order harmonics (which are typically not perceived as distortion by most listeners).

You can freely add all the harmonics and distortions you want if that is your artistic intend while recording/mastering. You'll encounter better and worse performing tools as you go through that.

You can pick to reproduce that recording/mastering utterly linearly, or add harmonics either inadvertently or on purpose.

Fundamentals and harmonics and whatever else will always be present in music. I hope it's the willful amplification thereof in the end chain we are discussing.

I’m not sure what GLM is.

DIRAC is interesting as most speakers do not have great impulse response, and there is not phase coherency. So using DIRAC to correct the speakers seems like a great idea to clean up poorly performing speakers.

Then the various room corrections make sense.

Do correcting the speakers and correcting the room seem like a good start.

I am as much TT as digital, or more so.
So I do not worry a whole lot about individual songs.
Since most preamps no longer have any tone controls it makes it a bot harder to just twist the (non existent) bass and treble knobs…

Hence I stay away from correcting individual songs. Whatever the cabal that made it came up with, i just accept it. (Or do not play it.)
Similar to how I do not always listen to every song on an album, with the exception os “The Streets” album “A Grand Don’t Come for Free”. ;)

Some people say that “the less the better”. Sound like you and I are in that group, where taming it to an extent and calling it a day is where we stop.

Impulse response is the delay on starting to sound a particular frequency? Then I understand the phase coherency…

I have Genelec 8030C, to my taste it sounds good, but I think for more accuracy on phase Neumann kh120 ii is superior, I’m thinking to purchase one unit and give a try.

Yes, I am as you in the group of just doing a little corrections, only for modes that bother me in barely all songs.

This is my 8030C room response from sweet spot, I only correct partially the 70 and 150 Hz spikes, the 1 kHz one because it scratch ears a little bit and rise very tiny the crossover ceiling cancelations at 2.5 kHz because are present in various measurements off axis and improve attacks. Treble boost at 4 kHz and up doesn’t make sense, seems a measurement error

I think we are in somewhat of agreement here.

I have no control over the musician and mixer/engineer.
But I do have control over extra distortion I add or not add.

Interestingly in Erin’s latest review of the Paradigm speaker he talks about bumping up EQ for ~100 or 120 Hz at 7 minutes in.
And he says he is targeting the 2nd harmonic of the drum’s fundamental. So it is like H2 solely for the drum.

How can you apply it only and exclusively to the drum, though? It may be more noticeable in the drum, but it'll boost that harmonic for everything that touches that frequency in the recoding, no?

Correct - but in his review Erin said he was targeting the drum specifically.
(I am just the messenger here, as they say.)

But if it had James Earl Jones singing, then yeah… his voice would also get the bump.
