This article gives a perfect example of how AudioBoom was used in a classroom of 2nd graders to improve reading fluency. To start using AudioBoom, click here and sign up.

What I like is that you can Upload any audio file and share it with an auto-generated web link and an uploaded picture, or you can click the Record tab and record your audio live with any microphone, and then save and post/share it online. AudioBoom keeps track of your posts on your Dashboard. Here is an example of what my first post looked like:
Here is how the Record screen looks in the web version.
