Violin timbre is a very complex case of study.The sound properties that distinguish an historical violin from a modern one are still not clear.The purpose of this study is to understand what are these properties, by means of feature-based analysis.We extract audio features related to timbre and we exploit feature selection techniques in order to investigate what are the most characterizing ones.We compare different feature selection algorithms and we illustrate how we applied their outcome to a classification task with historical and modern instruments.Results show that the classification performance improves when using the selected features.
