提出了一种利用元胞自动机进行二进制数据描述的新方法。作为一个实际的例子，进行了几次试验来描述以标准数据格式数字化的人声和音乐声数据。通过“实际聆听”、计算相对于原始声音数据的“信噪比”以及将“傅立叶功率谱”与原始声音的功率谱进行比较，对再现的声音进行评估。结果表明，该方法是一种有效的数据压缩方法，适用于任何数字数据记录和传输领域。
A novel method of binary data description using cellular automata is proposed. As an actual example, several trials are made to describe vocal and musical sound data digitized in a standard data format. The reproduced sounds are evaluated by "actual listening", by calculating "the signal to noise ratio" with respect to the original sound data, and by comparing "the Fourier power spectra" with those of the original sounds. The results show that this method is quite effective and provides a new means of data compression applicable in any field of digital data recording or transferring.
