One of the tools I fond in my web 2.0 tools research was the one called MYNA. It is the Aviary’s browser-based audio editor. Aviary is a powerful suite of browser-based design tools for people who create. It's free to try their tools or sign up! You do not need to download the program!
Some of the uses are to remix music track and audio clips. I have not used personally, but the demo is very convincing! I hope to present this to my colleagues to put it into practice in our classes.
Myna has a powerful clip editing. It also has effects. You can import or export your audio files to your desktop. You can also collaborate with other users. For more information watch the following video.
