Wow, @mahgister who the heck said room control only addresses the frequency domain.
I said my tuning adress LARGE band frequencies range... LARGE not specific precise frequencies... When we tune a room for a nuance of timbre we adjust a LARGE band of frequencies; this means that with our EARS when we listen a human voice we tune our resonators grid for the encompassing large band of an instrument or a human voice ... Read me right before putting words in my mouth...And anybody know that Fourier analysis adress sound in his LINEAR MAPS and use a specific abstract time domain which is not the time domain on the concrete human ears/brain... As muuch as the map is not the territory because the ears/brain dont work in a linear way at all but in a non linear TIME DOMAIN ...
Only a digital system can affect time by delaying groups that are ahead. Phase can also be corrected.
For sure DSP advanced as the Choueiri filters BACCH do it very well it is an acoustic revolution... But even Choueiri Filters DSP cannot replace small room acoustic...No DSP replace physicaL acoustics or work as Helmholtz resonators...I plan to upgrade my system by this DSP of Choueiri an acoustic genious..
The time domain for the human ears perceiving act must not be confused with the Fourier mapping of linear frequencies analysis of abstracted factors as phase , frequency and period etc ...The ears/brain work non linearly , in the opposite the Fourier analysis work with abstract concepts which are linearly related .. This is why we had not understood all hearing mysteries to date and why there exist competiting complementory theories of hearing... Go and read about ECOLOGICAL theory of perception for example and try to understand why these theories exist in the first place...
There is no such thing as a tuned acoustic room. The best you can do is Boston Symphony Hall and I doubt you are going to stick one of those in your house.
In APPLIED acoustics, there is a great difference in using the same laws and principles when you work in THE ARCHITECTURE of great Hall Acoustic and very small room acoustic ... You dont use time measured parameters in the same way for example...You dont use the pressure zones distribution the same way either...
When i spoke about TUNING a small room , i was speaking not ONLY about material passive classical balanced treatment in absorption/reflection/diffusion, i was thinking of working with a distributed grid of 100 mechanically tunable Helmholtz resonators... Do you catch ?
My brother is a MIT Ph.D. acoustician and he never uses his ears for anything!
My mother is a very good cook , i am not at all a good one... 😊
The problem is not the ear or ears. It is the brain connected to them.
What are you talking about ?
The brain of a musician and of an Applied room acoustician who work for customers wanting to design small acoustic room for themselves is TRAINED by ears , they dont used only DSP and tools...They listen... Ask Floyd Toole ...or any acoustician working in APPLIED acoustics...
Acoustician teaching in university taught mathemathical formulas and basic experiments and work in refined scientific projects... Their job is not designing small room with tools and ears...
Ears/brain is the basic object of study in psycho-acoustic...The brain is no more a problem than the ears they are coupled and tested in experiments about the way human perceive LARGE band frequencies bundles called human speech or singing not in the abstract Fourier time linearly MAPPING domain but in the real concrete time domain... The map is not the territory... Do you catch ?
Then recommending to people that they must forgot about their allegedly deceptive brain/ears and trust ONLY tools , saying that audiophiles must not train their listening of sounds through simple experiments and through listening classical music , (non amplified) or jazz etc but must use ONLY DSP is preposterous ignorance...
Electronics EQ is useful but do not replace ears nor small room acoustic... Eq and Ears do not work the same way ...Simple... They are complementary tools in acoustic room design ... it is so evident i cannot say more...
