I have just bought HF 2017 and there is a promo on the website with one paragraph on how great the new Audio features are. But I don't know how to do what I want to do. In Audacity you can sample a section of audio that should be silent and then apply that noise reduction to your whole clip. Works great. Is there a similar function in HF? Also, is there a wise and generous person who has or is going to make some video tutorials on using the great new audio features in HF 2017??
