I could swear that someone had a patent and was working on an audible crack detector but I can't seem to find it.
US Patent 4,602,147
"This invention is directed to a cooking control method and apparatus for food products which emit sounds through the explosive release of steam and gases generated by the cooking process. The system includes automatic control circuitry which is enabled by the detection of the audio energy created by the cooking food products and which provides a control signal upon the cessation of the noises generated by the cooking process. This control signal may be used to energize an indicator but in preferred embodiments, the control signal is used to terminate application of cooking heat.
By way of example, this specification is directed to a device for roasting coffee, one of the food products for which the noise responsive timing means is designed."
