Industrial Automatic Control Systems and Controllers Annotation << Back Determining the Type of the Codec Applied While Compressing an Audio Message A.V. Scurnovich, A.A. Dvilyansky, A.P. Ryzhkov, A.A. Borsch, A.M. Revyakin The article describes a one of the options for composing a recognition system to solve the problem of determining the type of MP3 codec used in the compression of audio data. The basis of the proposed system is the Bayes classifier, and the statistical characteristics of the elements of the block of service data of MP3 files are used as signs for recognition. The results of the experiments to assess the effectiveness of the proposed approach are presented. Keywords: type of codec, MP3 format, informative features, recognition.
