Happy Baby Screech Machine
This piece uses the circuit from a “super smart” baby doll. It has a communication panel on its chest that it uses to “talk” with other “super smart” babies and big sisters and puppies etc. I patched some of the signals from the communication board into the main sound board. This created two sound sources, the sound made by amplifying signals from the communication board and the sounds from the baby sound effect chip.
It’s one of the best random screeching noise circuits I’ve ever found. It does rhythms, evolving patterns, piercing noise, and every once in a while you’ll hear a child’s voice say something like “I love mommy” or “I’m hungry”. You have to listen to the samples to understand the variety and intensity of sounds this piece can make.
