[LAD] Is there an LV2 plugin that can add echo like echo added by large cathedrals?

[Yuri]

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
