There are conflicting reports as to how Godzilla's footsteps were created. One claim states that they were created with a knotted rope hitting a kettle drum that was recorded and processed through an echo box. Some Japanese texts claim that the footsteps were sourced from an explosion with the ending clipped off and processed through an electronic reverb unit. However, Ifukube told Cult Movies that the footsteps were created using a primitive amplifier that made a loud clap when struck. The optical recording equipment contained four audio tracks: one for principal dialogue, one for background chatter, ambient noises, tanks, planes, and one for the roars and footsteps. An independent audio track was used to prevent bleeding over other audio.
