The present code is a Matlab function that implements a novel technique named “statiogram” concerning the estimation of the short-time stationarity frame duration of a given nonstationary signal. The technique gives an answer what should be the length of the frames into which a nonstationary signal is divided, so that the signal be considered as short-time stationary. This is of particular importance when one is going to perform some kind of time-localized analysis or processing e.g., STFT, short-time energy or zero-crossing rate computation, speech processing etc.
A few examples are given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.
The code is based on the theory described in:
