Solid-state Halloween controller and how to build a Haunted House

Step 6 Create the soundtrack

Once you have a design in mind, create the soundtrack. Using a wave file editor, I sample, cut, and paste sounds from Halloween CDs. The best ones are meant to be copied and the sounds are separated into individual tracks. Heres the mpeg soundtrack to one of mine: halloween2002soundtrack.mp3 below. First, theres the sound of an angry mob; then a clap of thunder; a guillotine blade falls and someone screams; finally, maniacally laughter fades into the darkness. Heres another that simulates a car crash on my front porch: halloween2001.mp3, also below.

An easier way to get a pretty good soundtrack is to play two sound-effects discs from different stereos at the same time. In isolation, one Halloween sound-effect after another sounds stilted, but two reinforce each other to create the perfect mood.
