For years, I used the (free) and highly effective Spitfish VST for de-essing.
The site which hosts it appears to be abandoned. Alas, I see no possibilities of it becoming a 64-bit plug-in. I have tried using it in 64-bit Sonar X1 but the settings simply do not get saved(!).
I am looking for an alterantive VST. Ideally, something free/low cost and very similar to Spitfish in its functionality.
Ideas?
