Sound Shuffler X 1.7Free
Sick of the default alert sounds that came with your Mac? We are too. This application will allow you to randomize the beep, each time it occurs. You can also insert your own sounds to the mix. Everytime your system throws an alert beep at you, you'll be welcomed with a randomly picked sound effect instead.
What's new in this version:
Added new 'Get More Sounds' button, which takes you to our site with lots of archived sounds.Improved the installer.
