Disclosed herein is a segmentation method, which divides an input audio
stream into segments containing different homogeneous signals. The main
objective of this method is localization of segments with stationary
properties. This method seeks all no-stationary points or intervals in
the audio stream and creates a list of segments. The obtained list of
segments can be used as an input data for the following procedures, such
as classification, speech/music/noise attribution and so on. The proposed
segmentation method is based on the analysis of audio signal statistical
features variation and comprises three main stages: stage of first-grade
characteristics calculation, stage of second-grade characteristics
calculation and stage of decision-making.
