Methods of sound card identification by recorded digital data  // Caspian journal : management and high technologies. — 2009. — №3. — pp. 22-28.

Methods of sound cards identification by sound files based on non-uniformities of hardware part are reviewed. Two methods of identification are considered: based on Gaussian mixed models and neural networks. Efficiency of both methods is shown, however accuracy of identification based on neural networks classifier is shown higher, than that based on Gaussian mixed models.

Key words: digital recording devices identification,spectrogram,linear prediction coefficients,cepstrum,artificial neural networks,Gaussian mixed models.
