Editing a Podcast

My brother asked me to edit one of his podcasts that he did with one of his friends. My brother recorded it using the program I use, which is Audition. 

My brother's friend is a professional axe smith. My brother is wanting to learn the ways of axe making and knife making. 

He is starting to interview many different blade smiths. I am helping him edit out the "um"s and "uh"s. 

The podcast was sixteen minutes long, and I haven't finished editing it yet. I'm at nine minutes so far into editing, so there's lots more to do.
