The National Audio Theatre Festivals (NATF) is a US-based organization sponsoring a yearly, five-day workshop on audio drama, voice-over, the audio arts, and other special training. Participants take classes on subjects such as voice-over and voice acting, audio engineering, Foley and special effects, audio playwriting and podcasting, and more. The workshop is helmed by professionals in the field and is frequently held in the city of West Plains, Missouri.
The last day of the festival is a live performance of audio drama, carried over local television and radio, as well as streamed live over the internet. The night's entertainment includes original radio plays performed by attendees, and a short workshop play written and produced by first-time conference participants.
