Hi,

I have found this compander' schematic:

is that this circuit is applicable for the ISD chip??

Do you know some schematics of compander that I can use with the ISD?

Thanks

I want to add a compander, I take the compander Schematics from PT-80 effect, but I think that I have to add some components.
So how can I put the compander into this analog design?:
