Adaptive Personal Tuning of Sound in Mobile Computers

An integrated methodology for enhancing audio quality in mobile computers is presented. The key features are adaptation of the characteristics of their acoustic track to changing acoustic conditions of the environment and to users’ individual preferences. Signal processing algorithms are introduced that concern: linearization of frequency response, dialogue intelligibility enhancement, and dynamics processing tuned up to the users’ hearing characteristics. The description of the algorithms implemented in the C++ programming language is provided. The processing is performed utilizing custom Audio Processing Objects (APO) installed in the Windows sound system. The sound enhancement package is managed with the user interface enabling a control over the sound system. The results of subjective evaluation of the sound processing methods and algorithms introduced to mobile computer devices are discussed.
