New algorithms were developed for discriminating wow from natural musical effects, such as: periodicity detection by means of autocorrelation signal, algorithm employing AR model for power line hum frequency detection and algorithm for estimating pitch variation curve employing wow tracking based on recording bias detection in magnetic recordings. Moreover, non-uniform resampling routine was implemented and applied to wow compensation. The developed algorithms were studied using real audio examples allowing a comparison of their effectiveness.
