Smile: Fletcher-Munson based de-harsher

Here’s a spin off product from Fletchy-Muncher, with Fletchy-Muncher we used knowledge of the Fletcher-Munson effect to spot harshness. What we did with Smile was to invert the curve and by that create a plugin to get rid of harshness. To make it more musical we added a transient recovery that keep the most prominent transients around 3.5KHz and a tube emulated distortion around 400Hz, just to warm things up a bit. We also included a LP and HP filter to filter out the very low and high-end that, depending on the material, can get out of control. In the donation version you also have mid/side processing which is essential when trying to sweeten a mix in a transparent manner.
So in short, Smile is a Fletcher-Munson based de-harsher.
