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.

Excellent App, Excellent Developer!

I’ve used this app for many years. It has frequently come in handy for many different kinds of audio work. It is highly configurable, and has a massive feature set. Works very well, and is very easy to understand.

Such a bargain! I don’t know what I’d do without this app!

Does one thing. Does it perfect.

Everyone who uses their Mac for serious audio needs this simple, intuitve, and solid app. From generating (and exporting!) waves, noise, frequency sweeps, phase alignment and more, this is the go-to app you need to quality reference and test tones.

Frequency sweep time doesn't work

Very disappointing. Sweep time is fixed at 10 seconds no matter what I put in the sweep time dialog box.
