cfxr is a Mac port of DrPetter's sfxr. In his own words:
Its original purpose was to provide a simple means of getting basic sound effects into a game for those people who were working hard to get their entries done within the 48 hours and didn't have time to spend looking for suitable ways of doing this.
There already was a Mac port, but I felt a sudden urge to make one with a native Mac UI, add some proper save/load, and learn Core Data and Bindings while at it. My version's called cfxr (as in "Cocoa sfxr").
ITISTODAY Oh man this is awesome! Very fun to play with. I'm not making any games right now but I can see how this would be incredibly useful. Thanks for making it! (Version 0.1.5)
