Automated Portable Cradle System with Infant Crying Sound Detector

This paper describes the analysis of sound signals specifically infant crying sound through audio signal digital processing for development of automated portable cradle system sound detector. The input sound signals are filtered to a certain frequency range in order to swing the cradle and then the signals are analyzed. In order to analyze the sound signals, the system undergoes a certain process which is audio signal processing. Certain signal processing techniques have been used to observe the waveform of the sound signals. The purpose is to compare between six different types of sounds visually. The results obtained shows that the sound signals are visually distinguishable with one another after applying the processing techniques.
