Darth Sidious' holograms have different distortion
sounds from the rest. Do holograms have personality, just like different Podracers? How
was this created?
This report comes from the Official Star Wars Site!

I tried to make the hologram sounds relate to the character they depicted.
The Sith hologram tonality is partly made on an electronic synthesizer. Two low frequency sine waves of nearly the same frequency are played at the same time. The slight difference in frequency produces a phenomena called beats (you learn about this in Physics class). The result is a wavering up and down in pitch of the sound. I also mixed in some short wave radio sounds that you can hear between broadcasting stations. This is one of my favorite sources of sound. Finally I added a very very slowed down sound of a jet plane firing a Vulcan Cannon, an electronically driven machine gun that fires 100 bullets per second.
