    Particularly in general I do not need this program. It was I already pre-installed on the laptop (Lenovo) and I somehow did not pay attention. And removing it, I have not noticed any changes not in terms of sound quality. Especially because there are many more useful tools for improving and sound filtering.

    Here is a question for you why would I want to download another verison when the one I pay monthly for does not work and I have to turn it off?
    Does this one do the same thing?
