I think what they want is a test tone used for calibrating your recording with someone else's audio system.

This is a pure sine wave which oscillates at 1,000 cycles per second (1kHz).

There is no way that I know of to do this within GarageBand, but it may be possible with the help of an additional program.

Does anyone know of an application for the Mac that can be used to generate test tones?

I found something:

Maybe this will help someone else

If you don't have a sound file with a -12dB 1khz sine wave test tone, Audacity can make one for you, go to the "generate" menu and choose "tone." The generator has an odd control for level, not in dB but in increments between 0 and 1, but you can always make the tone, then go to the "effect" menu, "normalize" it, then reduce the gain by 12 dB with the "amplify" effect. Then export that as a .wav file and keep it to insert in future sessions as a reference.
