Do you need different equipment and recording methods to create a “highly-produced” podcast?
The short answer is no, but we'll be taking a look at this question in more depth on this episode.

There's definitely an overlap here with recording “standard” podcasts, but it never hurts to revisit these good practices and always ensure we're recording good source material to work with.
