I am a member of a team that has developed a user-friendly, web-based recording and collaboration studio called Soundtrap. It has been appreciated by hundreds of schools around the world, for music education and production, for making podcasts etc
One reason for being popular, except that it is easy to use, is that it can be used for free. Most features, including a video chat, are available free of charge.
Soundtrap was awarded "Best Website for Teaching & Learning 2015" by American Association of School Librarians.
Could this be interesting for the educators attending the Global Education Conference?
Here are some articles describing how Soundtrap could be used:
