Quality Audio = More Listeners
It's a fact that listeners judge the quality of a podcast by the quality of its audio. Yes, "content" is important, but like the cover of a book, your audio quality is an easy way for listeners to tell if you've spent time on other important elements of your podcast.
This issue has three things you can do right now to make your podcast sound better. One is how you communicate with "remote" guests, there is a $35 "studio" you can build yourself in about 20 minutes, and the third is a piece of software that will "fix" problems in your recording with a single button.
Plus, something to think about if you're nervous about "big money" coming into podcasting.
I hope you're finishing out a great week! If I can do anything for you, reach out to me via Twitter.
