WIDER is great. Simple to use and works as promised. I love this thing.
I paid for Nugen Stereoizer, but was tired of licensing crap...and what if the company goes out of business? I'm stuck with useless software.
The additional benefit of WIDER, which I see less and less of these days, it's that it's a no-strings attached DLL you drop in and use. There are some paid ones (Klanghelm, Brusfri, etc.) that I have paid for and also are this simple.
I would pay for WIDER. It's that good.
I'm over "management layers" or "licensing layers" or buying into an ecosystem. Drag and drop DLLs that do the job...and do it well, are my future.
