A novel method of sound data description by means of cellular automata andits application to data compression

A novel method of binary data description using cellular automata is propos ed. As an actual example, several trials are made to describe vocal and mus ical sound data digitized in a standard data format. The reproduced sounds are evaluated by "actual listening", by calculating "the signal to noise ra tio" with respect to the original sound data, and by comparing "the Fourier power spectra" with those of the original sounds. The results show that th is method is quite effective and provides a new means of data compression a pplicable in any field of digital data recording or transferring.
