In this paper the basics of data predictive modeling (using the method of minimization mean square error) for lossless audio compression are presented.The described research focuses on inter-channel analysis and setting range of prediction in dependencies of frame size.In addition, the concept of data flow using inter-channel dependencies and an authorial, effective and flexible method of saving prediction coefficients are presented.In this way we obtain a difference signal in which the distribution of errors e(n) has a character similar to Laplace distribution, which allows for efficient coding using one of M Analysis of inter-channel dependencies in audio lossless block coding
