Abstract :
The theory and encoding display method for sound holo-spectrograms are presented. A criterion for deducing phase instability is introduced. The holo-spectrogram contains both phase and magnitude information of a signal in the time-frequency domain, which can be applied to the study of speech analysis and other forms of acoustic signal processing
