We used DELAY (U_2) to put the phase shift on 3kHz sine wave.

You may see spectrums by choosing "Open a Monitor" on each FFTMON.

And you can save the sound into a Wave file by choosing "Tools" -> "Save Wave" on the menu.

That's it for this class. Some people say the phase shift is important for the quality of music. However, normal people cannot hear the effect of the phase shift.
