SoundCloud

SoundCloud (http://soundcloud.com/) is a free, web-based audio tool that allows users to publicly or privately share recorded or uploaded audio content. SoundCloud provides data on number of plays and profile views and can be pushed to various social networks like Twitter and Facebook. Instructors could record and distribute podcast lectures through SoundCloud, and students could themselves develop audio content to share with teachers and classmates. Free accounts require sign-up but provide 120 minutes of storage. SoundCloud is also available on the iPad, the iPhone, and Android devices.
