Vacaroo is a one of the quickest way to record an audio file.  Students an record their voice during fluency reading practice or make an introduction podcast and embedding it on their own blogs or class website.  Vacaroo is a very simple site to use and navigate around.  To start, click record and when you are finished download it, embed it, and/or share it on certain social medias.  Vacaroo is completely FREE, so I encourage you to try it out.
