The organization Transom is a wonderful resource to learn more about radio-making, podcast equipment, storytelling techniques and functions as a public media performance space.
Their website features tools, techniques, workshops and their very own podcast, HowSound, on radio storytelling.
"Transom channels new work, voices, and ideas into public media through the Internet and workshops. Our goal is to be useful and inspiring. Transom is a performance space, an open editorial session, an audition stage, a library, and a hangout. Our purpose is to pass the baton of mission and good practice in public media through tools, philosophy, and technique.
