@ARTICLE{Maziewski_P._Wow_2006, author={Maziewski, P.}, volume={vol. 54}, number={No 4}, journal={Bulletin of the Polish Academy of Sciences Technical Sciences}, pages={469-477}, howpublished={online}, year={2006}, abstract={In this paper the capacity of non-uniform sampling rate conversion techniques, involving different interpolation methods, aimed at wow defect reduction, is examined. Involved are: linear interpolation, four polynomial-based interpolation methods and the windowed sincbased method. The examined polynomial methods are: Lagrange interpolation, polynomial fitting with additional noise reduction, Hermitan and Spline. The performance of an artificially distorted audio signal, restored using non-uniform resampling, is evaluated on the basis of standard audio defect measurement criteria and compared for all of the aforementioned interpolation methods. The chosen defect descriptors are: total harmonic distortion, total harmonic distortion plus noise and signal to noise ratio.}, type={Artykuły / Articles}, title={Wow defect reduction based on interpolation techniques}, URL={http://www.journals.pan.pl/Content/111742/PDF-MASTER/(54-4)469.pdf}, keywords={Wow defect reduction, audio signal restoration, linear interpolation, Polynomial interpolation, sinc-based interpolation, nonuniform sampling rate conversion}, }
