OTT was a multiband compressor setting. It was called “over the top” or short OTT. For about 15y now it’s been an industry standard for EDM. Technically a lot of other compressors might be able to replicate (assuming they simulate the same crossovers and upward as well as downward compression), but it still is a very specific configuration.
Hey, I have a lot of experience with music production but I’m not familiar with OTT, from a cursory search it seems to be a multiband compressor?
Calf multiband compressor is very good but it is GTK2 based so you have to use a generic UI in the latest version of Ardour.
What DAW are you using on Linux?
I think the special thing about OTT is that it does upward and downward compression at the same time.
Looks like LSP Multiband compressor has an upwards mode but you might need to chain two instances to do both upwards and downwards: https://lsp-plug.in/?page=manuals§ion=mb_compressor_stereo

Hope this helps.
