hi,
looking out for ott style compression abstraction/patch.
that's it.

@breze Multiband compressor.
First problem is splitting the signal into ranges and preserving the phase relationship.
That was done here........ https://forum.pdpatchrepo.info/topic/7006/multiband-compressor/4 in the patch posted by @seb-harmonik.ar "multiband_compressor.pd"
You will need some externals... at least the iem library, maybe others.

You could replace the [pd compressor] sub-patches with the one to be found in the Pd audio examples folder...... pd/doc/3.audio.examples/I05.compressor.pd
That will do very OTT without having to set envelopes... good or bad depending on what you want to be able to do.

@whale-av
thank you very much!

i'm on ios plugdata.
i think i cannot use the iem lib filters.
but i also think any lp hp would do.
butterworth3~ from vanilla?

the compressor used in the multiband example is from
http://pd-tutorial.com/english/ch03s09.html

a very interesting chapter about limiter, compressor, expander.
think i will start from there.

the other example you mentioned from pd audio examples...
somehow very strange kind of compressor:)

and
i tried from the else library else/norm~, which seems to do sort of normalising/expansion thing.
