Gosh how can you compare the tools in Stereo tool are superb.
I just want to know what else they can do

It seems there may also be a FM declipper too. but i am still trying to figure that out . If its streamed content than you can use all the lovely things above especially with the DSP version that integrates into other players. They are all pretty amazing .
I only have problem with dehummer but I think that will be my set-up as it currently using my settings adds lots of reverb to tracks without a hum or at least this is what I have found . The only problem i had a startup was deciding what to turn on

This Dehummer is now off . Crumbs your web site radio link distorts.
