A friend of mine asked me to take his father's acetate recording from 1955 and "clean it up" for him. I tried Bias Peak Sound Soap... the results weren't great. I tried Steinberg's Denoiser... the results were marginal with a fair amount of background "chatter". So I downloaded the Redunoise demo plugin by Voxengo... it was great... the best results by far. So I ended up buying it 15 minutes later.
I was searching a pro audio forum one day trying to find a good noise reduction plugin. Someone made the comment to get over the "free" plugin mentality and spend money on a quality plugin. He suggested that Redunoise was unbelievable for the money with outstanding, accurate quality. I tried the demo and quickly purchased it. I have now also added PSL, Voxformer, CurveEQ, and Lampthruster to my line up. The results are so perfectly musical! And the prices are unheard of. I wonder how much I would need to spend on external gear to end up with the same sonic results. And all the plugins travel so nicely on my laptop when I'm out of the studio. These plugins are worth far more than is charged. Voxengo gives me the perfect sound every time. I cannot say enough about the value and quality of each plugin I've tried. Good work Voxengo.
I thought I'd drop you a note just to say that I have no negative issues with the plugins. I like using all the ones I have and love the sound. I find them easy to use and understand. The pricing seems very fair to me as well. I also wanted to especially note the look of the plugs. I prefer the straight forward layouts as opposed to very elaborate GUI's or emulations of "vintage" looking devices.
