NOTE: iTunes doesn't accept caf files. On OS X 10.8 and up, you can open the caf file using QuickTime Player, and export directly to iTunes by choosing "Export To iTunes..." from the File menu. On OS X 10.7 and earlier, you can covert the caf file to an m4a file using QuickTime Player, then add it to the iTunes Library. To convert, open QuickTime Player, open the caf file, choose "Export..." from the File menu, save, and drag & drop the saved m4a file onto "LIBRARY" on the iTunes window or choose "Add to Library..." from the File menu in iTunes and select the saved m4a file.

Delivers ! - I am an engineer, musician, scientist and this app does exactly what I needed it for and more. I love the fact that I can save frequencies for recall later. Great job ! First Sound generator I ever used was the old desk top models and I was right at home with this virtual version. Thanks !
