Wavelets in elimination of distortions in the recorded violin sound for main and mixed playing techniques

摘要

The result of the research on recognition and processing of violin sound is presented in the paper. This paper shows how to achieve higher quality of recorded sound, which is closer to human's subjective perception, using signal processing and algorithms, which preserve playing techniques and individual style of the violinist. The filter, which provides the best result as well as perception and data analysis spectrum is a one-shot filter based on wavelet transform, with experimentally designated universal wavelet form for each technique. The work also delivers such information as safety and optimization way of processing audio parameters in the production code.
