I've been using Adobe's beta free podcast audio conversion tool. I know this will eventually become part of their paid platform so I was looking for more cost effective alternative. THIS IS IT! I uploaded my first file and the noise reduction is ridiculously fantastic. Unless you have a room which is specifically soundproofed you will end up with just passable to bad audio quality. With a tool like this, you just throw that audio file into the platform and it spits out, podcast quality sound, like magic. highly recommended!
