In my search for good audio tools, I found UJAM, a free tool for recording your voice, creating a song, converting your voice to an instrument...you name it. You can see a beta walk through on YouTube, but basically, you sign up, record into your computer's microphone, and make a few manipulations--presto, a song. You can edit chords, the song melody, add instruments, etc. Or you can turn your voice into an instrument! This might be a good tool for musicians, music teachers, and certainly for budding rock stars! Maybe it would be good for unique exercise in a poetry class...the spoken word as song.
I was amazed at how intuitive and easy this tool is to use to create quizzes. I had spent hours creating a PowerPoint quiz, and minutes to create the same quiz using this tool. Plus I had much more flexibility in kinds of questions I created--and I can gather feedback any time I want to. There is a free trial version of this tool, and then one must purchase the rights to use the tool. Try it!
