Holo-spectrogram and multi-dimensional encoding display
The theory and method of the sound holo-spectrogram are presented. An experimental system is developed, which is based on a multi-dimensional encoding display technique. The principle of the multi-dimensional encoding display is given, and the choice of encoding domain is discussed. The display maintains magnitude-greyness modulation in the conventional sound spectrogram, retains all signal information in the time-frequency domain. The holo-spectrogram is applied to the processing of speech and other acoustic signals. Some experimental results are given. The multi-dimensional encoding display can also be used in the analysis of the two-dimensional spectrum in other transform domains, such as the spatial frequency domain.<>
