I've heard a lot of positive comments on here re software such as iZotope for noise removal. I have the below audio from a wedding recently where many times when the bride spoke a door somewhere at the back of a (large!) London church was crashing shut. I've tried to improve it with my limited noise removal skills using Audacity, but without anything like success. So...wondering if anyone here can do anything with it? Frankly I'll be amazed, but then I'm no audio guru! Link below.
