True or False?

Don’t get me started on room correction. What a nightmare. Get a test CD (Stereophile for example), and a sound measuring device. Run the test in your room at listening position. Look at the frequency response. Gaps, holes, peaks? now what is causing it and what does it take to fix it?
not fun.

It is all relative to the road taken...i had the fun of my life with room correction...

I used a mechanical equalizer (32 tubes and recycled plumber pipes with straws for neck all variable and different for volume/lenght/ diameter ratio) which will become part of my audio room...Not an electronical equalizer with a mic.

I used the timbre of voice or instrument instead of a set of limited tested frequencies response and my Ears for the feed back instead of a mic...

Results: the 2 listening position which are good are large enough and not a very narrow one in millimeter out of which no measure means nothing...
I control all aspect of acoustic at will: imaging, timbre perception, soundstage, listener envelopment ,source width...

Is it perfect? no

Is it good? so good that i "trash" all my headphones (7 pairs) and my average speakers work at their best.... Because like Helmholtz i modified the room response and tuned it to the speakers or instrument which was playing...Not the opposite modifying the speakers or the instrument for the room...

You can chose for sure to modify ALSO the speakers response to some set of frequencies but it is good for a last fine tuning, that will NEVER replace room passive material treatment at all, and that will NEVER replace my activation of the pressure zones of the room by mechanical means...Passive materials treatment in small room must be done using in a positive way the timing treshold and reverberations of the small room... The mechanical equalizer is used to mark out or to " buoy" the waves of EACH speaker differently FOR EACH ear, making the brain easily able to recreate 3-d directions and image in the room....

It is was fun and rewarding ....It takes me a month.....It is like tuning a piano...

The room geometry and content is like the piano particular form and the pressure zones are like string tightly vibrating or resonant.... At the speed of sound, waves may cross a small room many times before the brain analyse them in some 80 milliseconds....Then acoustic of room is not only a set of passive wall enclosures waiting for the sound to bounce politely on them it is a complex distribution set of pressure engines...

I dont need a Smyth realizer headphone anymore...

cost: peanuts

Inconvenient: impossible to put this unesthetical devices in a living room...







The only luxury in audio is not costly gear it is a dedicated room....

A straw can kill a room or transform it completely...

Embed everything before upgrading anything...

Good listening skills for musical playback enjoyment include the ability to mask out unwanted sounds and anomalies and reconstruct in our heads things that aren’t really heard. Bad listening skills would be to be able to hear things as they really are. If you could do that, you would never hear a phantom center image. You would always correctly interpret all the sounds to be coming directly from each speaker. That would suck. Nothing wrong with learning to better imagine sound that isn’t there, except perhaps that it can make us vulnerable to magical claims that are sometimes rather expensive if we don’t remain aware of what’s going on.

Psychoacoustic has laws about timing threshold of wavefront from direct, early and late reflections and from back reflections for example...

These laws has nothing to do with bad or good listening skills...These laws work for anyone.... If you come to my room you will listen the 3-d holographic as real this illusion is for me....

You apply them and you will listen to a holographic 3-D real illusion which you can control in some way and modify at will....And applying these laws in my room dont make me "vunerable to magical claims".... It is the opposite, because i know how to create any "illusions" out of my mechanical room controls...

Then i dont fall for cheap costly acoustical "tweak" sells to those who dont know how ton control their room...I will not name a company here.... 😁

In acoustic, an  illusion controlled is the perceived reality....

The tweak eliminator in my experience is good room treatment.

People get off the merry-go-round of buying hardware and cables and fuses pretty quickly after they’ve done that.

Wise observation!

Controlling vibrations,decreasing the electrical noise floor and controlling acoustic are not "tweaks"...

They are first necessity for any working systems to reach his peak optimal...

It is called " embeddings controls" to not confuse them with secondary "tweaks" like cables, fuses, etc....

Maybe not so much in a higher humidity climate.. Zone exclusive tweaks..

A fine brain with a big heart indeed!

Or a big brain with a fine heart.....😊 I am not sure....

You dont need "tweaks" or upgrading for your soul for sure...You even treat your chickens well and even feed them too much....

For your audio system i dont know, because i dont have listen to it....But  i always trust a mechanic who like pipe organ....

For sure the costlier a system is, the more it seems for the owner that his system is "immune" to any embeddings controls...There is some truth in this because the engineering is more sophisticated to a point...

But no speakers at any cost beat  the vibrations aggression , a too high  electrical noise floor in the house nor acoustic control...

Embeddings controls are not for the gullible crowd unable to afford 100,000 bucks system but for all of us....It may cost very low....


By the way it is not necessary to prove or measure anything... We are  in audio listening experiments  not in a reunion of the "sunday club scientism and skeptic association "....

BUT someone that’s using cabling to modify the way something sounds... NO!

Very right....

Not because cables are all alike but because they cannot beat control of vibration neither compete with the decreasing of the electrical noise floor, and beat acoustic passive treatment and compare to active acoustic control...

CAbles change are SMALL compared to all that...

I dont understand fixation with cables, those who negate that they are different which is evident and audible and those who pay a big amount of money vouching that they transform all their system...

The 2 groups war between each other blind to the more important way to improve their system....

Incredible!....

Our friend mechanician is right, the power supply and the electrical grid of the house are way more impactful....  

FALSE, the cost doesn't matter. Tweaks are useless in an inexpensive, moderate or expensive system.

Are you born with innate audio knowledge?

Vibrations?

 High electrical Noise floor?

Acoustic?

That did not ring a bell in your cranium at all?

Stop calling that pejoratively "tweaks" and think about common sense solution .... They could cost nothing...

 

Room corrections are not tweaks in my view. That is room correction. Not a tweak to me.

Vibrations controls is possible at low cost, it is not a "tweak", it is an embedding control, not a secondary addition, a fundamental necessity...

Decreasing the electrical noise floor is possible at low cost also... It is not a "tweak" it is a fundamental necessity...


Room passive material treatment and ACTIVE mechanical control is not a "tweak" but a prime absolute necessity to hear our system at his optimal working peak...

"Tweaks" are most of the times pejorative qualification for the "supertitious" people who believe that their costly system can work optimally without any "embeddings controls" like in the publicity they read before buying them ... They bought it, plug it and boast about it ....

And before buying costly "tweaks" try to replicate them yourself at no cost.... Often it is possible...It is way more rewarding than buying....And more fun....

😊

Audiophiles have infinite hearing, allowing them to hear down to ever lowering "noise floors" that no manufacturer’s equipment can measure.

Incredible insulting and stupid "preaching" post about all "audiophiles" indiscriminately in a polemical narrow mind way...

Do you realize at which point you go astray?

And you pretend to rationality in addition.... Funny..... 😊

Tweaks are for idol worshipers. If it works, it is not a tweak but rather an essential accessory.

I agree for once with you...

I call them "embeddings controls"...

The more important embedding control is the acoustical one...So impactful that if rightfully implemented almost any upgrade is no more so "sexy" ...

The ratio S.Q./price is the only way to keep money and not throwing it to the hype wind.... For those of us like me less fortunate and more creative....

I never bought any "tweaks".... i prefer to create my own "embeddings controls" at NO cost or almost....

Not only it work but it make my maxim truer with time passing:  embed it all dont upgrade before....
