We know how important it is for producers to get feedback about their work. We would really love to provide notes and critiques to every one of our producers, but unfortunately we don't have the editorial staff to do so.
We always suggest enlisting your friends and colleagues for feedback. If you're just starting out and don't have a lot of radio/podcast colleagues, try expanding your network by joining a local podcast club. Also check out organizations like AIR, which is a community of independent producers.
