ACME? Meep meep 
This sounds like a 60 Hz mains power hum. You can only solve this if you know where it comes from.
Is it really the compressor? Do a direct loop test first (audio interface outputs --> audio interface inputs) then substitute it with another effects unit.
Is the hum still present with the input jacks disconnected?
No? Then either "garbage in garbage out" applies, or you could have a ground loop which is a huge topic in itself.
Yes? If this is an old unit, its capacitors in the power section might have gone bad. Or this is natural for this device and you boosted the recording level far over what's normal: pilot error. Analog tube stuff always has mains hum to some extent.
Any way, we need more information and you need to do some tests.

We are the KVR collective. Resistance is futile. You will be assimilated.
