Doesn't hurt to have a free product in my tool set

The best support comes from communities and blog posts, but there really is no authoritative answer for anything. You basically have to wing it. However, since there's no financial barrier to entry, everyone is creating their own help documents so you're bound to find a solution.

Audacity is a free open-source product that does a great job with audio editing, handling pretty much all files with ease. While out of the box, you may require some free plugins to process the audio file you work with, some of the functionality for more advanced tasks requires paid plugins that may not necessarily even resolve the issue. In particular, Audacity doesn't seem to have a seamless solution to remove echo, and many of the various help documents seem to suggest that a paid plugin would resolve this issue; none of them work. The interface looks very professional, but to that end, it's also intimidating to use and it's difficult to figure out how to do things at times. You may need to refer to help documents on a regular basis; for every podcast I've recorded, I've had to revisit another help issue. I've done more than 40 hours of editing since I've started but I still don't feel confident I understand how to amplify the volume in text or to reduce it. I feel like a newbie and perhaps I shouldn't be one at this "late" stage. That said, Audacity is perhaps one of the best audio solutions on the market, and it doesn't hurt that this is free.
