The Cabinet of Dr. Fritz was a 1984 binaural radio drama series produced by Thomas Lopez and the ZBS Foundation for NPR.

“Fritz” was the nickname Lopez gave to the human head-shaped microphone he and his team used to record their three-dimensional productions,[1] but its official name was the Neumann Ku81 Dummy Head.

A solid rubber head with microphones set inside the ear chambers,[2] it was designed to record sounds the way a human being would hear them.

Lopez recorded the drama on location, with actors performing for the dummy head microphone in an actual abandoned house across the Hudson River from where he lived.
