I downloaded Noisegator, but it keeps crashing

Hi, I saw that there is a program called Noisegator that we can download and install to minimize background noise. I checked it already and on the page, it said that it had some issues so it cannot be downloaded at the moment. I tried to download it but tue page kept on crashing.

Now, my question is that, do you know any other program that works similarly like Noisegator? I am now using a noise-reduction Logitech hheadset. Planning to buy a Plantronics soon. But for the meantime, maybe I can supplement it with a program such as Noisegator to cancel background noises.

I hope you can share what you're using. Thanks a lot. I really appreciate your inputs.
