Elimination of distortions in the recorded sound of the violin using cascade-integrator-comb filters based on Gabor transform and pitch-shifting algorithm

Abstract

The topic of sound recognition of violin playing is still at the top of research. This paper shows how to achieve higher quality of recorded sound using signal processing and algorithms, which is closer to human's subjective perception such as — safekeeping of using violin playing techniques and behavior of the player. The filter, which provided the best result as well as perception and data analysis spectrum is a cascade filter based on Gabor transform, with experimentally designated coefficients for each technique.
