Where can i find measurements of “the studios” for learning

[sukoon]

where can i find the measurements (REW) of the best studios in the world, pre and post acoustics, pre and post eq
i have my room measurements and want to compare data like clarity and rt60 and more.

above all where can i find the expected ideal listening room measurements / settings to be such it qualifies for a listening studio

These measurements are rare.
Measurements on different devices like amps or speakers show often almost ideal responses.
It is very difficult to get a room measuring that way, so a lot of room designers choose not to show measurements.
On the studioforum of gearspace you see some measurements on rooms and discussions about them.

Yes you would imagine that having created a superlative room the designer ( there is a thread somewhere here with a contribution by the Northward guy) would only be too eager to share, but no.
Having said that I may still have some measurements from a few studios where I have demonstrated loudspeakers one in particular which was a room within a room built into a very unglamorous industrial unit, absorption provided by bed mattresses loads of them, which measured very well.

I don't think you will find such detailed information on many studios.

There's not necessarily an agreed upon ideal either. But there are some standards (standard in the sense that someone created them and called them a standard, not necessarily a standard in the sense that they are followed by most studios) you can look up. But they too are somewhat open to interpretation and/or allow a range.

I created similar thread some time ago but never found anything in depth. I saw some glimpses of measurements of Northward rooms made by them, but they only shared extremely smoothed response, only in the low end and only before any furniture was brought in. No spectrograms or anything. As far as decay goes, I can tell you from experience that if you manage to keep the low end below 400ms or so and the rest around 200ms (close to 100ms is claustrophobic and 300ms becomes roomy) in a small room then you're golden. Dirac ART is able to tighten the low end to 200ms, I don't think it's really possible to go below that in a room but that's extremely short, on the other hand above 500ms is rather long for music production as it's hard to judge kick length and bass instruments can sound muddy

I would not call 1/24 octave band graphs "extremely smoothed".

I'm in the middle of re-reading Floyd Toole's book...

Floyd Toole calls this The Circle Of Confusion. We don't know what the studios sound like and they don't know what our homes sound like...

He also discusses that there are differences between what a microphone measures and what we hear (above the transition frequency). Our ear/brain tends to separate the sound from the speaker from the reflected sound and sometimes "correcting" the measured response makes it sound worse because what we hear from the speaker is "not right". (At lower frequencies room measurements ARE good for identifying standing wave problems in the bass range at the listening position).

and want to compare data like clarity and rt60 and more.

And he says, mixing & mastering engineers often prefer a "dead" room for production and a more reflective room at home for listening enjoyment, especially when listening to classical or jazz.
