The present invention provides means of identifying a sound or acoustic event and converting this into suitable information for the user. This may be used for remote monitoring, for defense, for health applications, and for helping hearing impaired people for identifying the sounds. The system may also be used by a user for source of sound authentication/identification system and method, in which authentication of a user (if the purpose) is performed by verification of the voice of the user representing his or her biometrics, unique to a desired user. The audio data is not required to be stored for the purpose, instead the statistical properties of the temporal and spectral/wavelet coefficients or the weights of the trained neural network thus ensuring security of the data and small size of the stored data making it suitable for applications such as smart cards. The system is able to function in high noise environment, and when there may be multiple events overlapping.
