Gentlemen, we are sorry for the "audio hampering", but without it TO SOME PEOPLE, the product is fully useable, along with an editor.
I am speaking from clear experience as we didn't do audio hampering in our DNoise demo we released several years ago. Within a week, our sales dropped to less than 1/20th and never came back up, even though this was the best noise removal tool on the market. In several more months, we found a French web site with over 40,000 downloads. So, you don't see DNoise in our price list today because it was basically put in public domain... as a very useable demo.
We will probably never attempt to remove reverb-echo, because many professional reverb boxes create DIFFERENT sounds for the left and right channel, making it impossible to remove with the current technology. This was pointed out to us by a musician / audio engineer schooled in the art of adding reverb.
We could set the amplitude of the audio hampering lower, and that will be considered. Thanks for the feedback.
