    Abstract: A method includes receiving, from a portable recording device, multiple recordings of sounds made by an elevator during operation of the elevator, the multiple recordings generated at different times. The method includes analyzing, by a sound analysis circuit, the multiple recordings generated at the different times to detect changes in an elevator characteristic over time and generating, based on detecting the changes in the elevator characteristic over time, a notification to perform an action on the elevator.
