An integrated methodology for enhancing audio quality in mobile computers is presented. The key features are adaptation of the characteristics of the acoustic track to the changing conditions and to the user's individual preferences. Original signal processing algorithms are introduced, which concern linearization of frequency response, dialogue intelligibility enhancement, and dynamics processing tuned up to the user's preferences. The principles of the algorithm implemented in the C++ programming language are provided. The processing is performed utilizing custom Audio Processing Objects (APO) installed in Windows sound system. The sound enhancement bundle is managed with a User Interface enabling control over the sound system. The results of subjective evaluation of the introduced methods are discussed.
