I remember listening to the talk of researchers who were traveling to
different old cathedrals, particularly to Hagia Sophia in Turkey, and
measuring echo in these cathedrals. Such buildings add a lot of deep and
very prolonged echo which depends on the building's shape and materials.
They were quantifying the noise response too.
Are there LV2 plugins that can add same or similar echo as cathedrals add?
Thanks,
Yuri

It sounds like what you're looking for is a "convolution reverb", if you
want to get the exact sound of a space, or just any reverb plugin if you're not too
fussed.
Normal digital reverbs use combinations of different sized delays to provide a dense
"wash" of sound. By twatting about with the phase through allpass filters and
having combinations of very long and very short delays that don't sync up - at least
one has to be modulated to stop it sounding "pingy", you can get a very
realistic reverb effect.
Convolution reverbs effectively multiply each individual sample of the incoming audio with
every individual sample of an "impulse" which is a recording of a loud bang in a
reverberant space. So, for each input sample you've got an output a few seconds long.
One single pulse - just a one-sample click - would play out the impulse, and a sustained
sound would sound like it was being played in that space. There are tricks to make it
less insanely computationally expensive, but that's basically the size of it.
Now even if you don't have exactly the answer, you've got the right words to put
into Google :-)

You are looking for impulse response (IR) / convolution plugins.
Some of such plugins:
KlangFalter from DISTRHO Ports:
https://distrho.sourceforge.io/ports.php/
https://github.com/DISTRHO/DISTRHO-Ports
Convolver reverb plugins shipped with Guitarix:
https://guitarix.org/
IR.lv2:
https://github.com/Anchakor/ir.lv2
and probably many more.
The impulse response files (the echo/reverb recorded) can also be found
online free and paid. Some may be shipped with the plugins (Guitarix
comes with 'greathall.wav' file).

You could ask CCRMA for the Hagia Sophia IRs.
Alternatively https://www.openair.hosted.york.ac.uk/?page_id=36 has a
few very nice ones.
St. Mary's Abbey has a very long reverb tail, as does the Hamilton
Mausoleum. Also check out the Spokane Woman's Club.
The Lady Chapel of the Ely cathedral is amazing, too:

Any convolver will do. Apart from the ones that others have already
mentioned:
https://lsp-plug.in/ has a very efficient and reliable one with plenty
of controls. If you want a simple one with presets-only (incl. the
openairlib) check out: https://x42-plugins.com/x42/x42-zconvolver
Cheers!
