you do realize that operations such as level shift e.g.
require buffered input . . . for all input components e.g. the level , the shift :D (actually not funny if you don't realize on time)
- i think . . . thus i am .. though there are a lot of such in your chain
- it seems your very input comes unbuffered + all op amps can't manage "level calculations"
how you track your phases anyway

I have no idea what you are talking about. Care to show and describe some examples where more buffers should be used?

e.g ? do my job -- then you can come and say "Look what i did!" (ordered) -- just like my dad , muhahaa :D
you do understand that this starts from veryfing the types of OpAmps used for this design for being capable of what they're doing there - individually - stage by stage
starting from - i have no idea what an audio compressor is - though i can track some ~ac arithmetic from single input to output
