Jeff and I recently had the pleasure of working on a fantastic animated project that featured an incredibly vibrant city park filled with pets. There were dogs, horses, cats, sheep--you name it. When Jeff met with the creator, she expressed that she loved the idea of having human vocalizations covering the main pets on screen. Jeff and I completely agreed since it really spoke to the hand-made, warm, and contemporary feeling of the animation.
In fact, we loved the idea so much that we decided to create our own custom sound effects for all of the animals using just our own voices and a microphone. Thus began what I now like to think of as The Day Our Neighbors Realized We Were Completely Crazy.
