Spreaker is a service for creating podcasts and broadcasting them to the world as live or recorded productions. If you want to simultaneously broadcast live and record your podcast for re-release later, you can do that too. The Spreaker virtual mixing board provides tools for mixing in buffer music and editing voices. The video below provides a brief introduction to Spreaker.
Applications for Education
Spreaker could be a useful service if you want students to record podcasts, but you don't have quality recording software installed on your school's computers. Spreaker has free Android and iOS apps that your students can use to record too.
