Abstract: The identification of musical instruments is one of the main areas of research to provide solutions to the need for automatic tools for indexing from the contents of recorded music. This paper studies the behavior of a set of relevant acoustic characteristics together with Gaussian Mixture Model, Support Vector Machines and k-Nearest Neighbor classification methods in the recognition of 18 musical instruments. Over 115,000 samples coming from TunedIt and another set of samples recorded by the author have been used for the experiments, reaching a success rate over 90 % in both cases. The study highlights that both the relevance of the acoustic parameters and the level of difficulty in identifying a particular instrument are related to the classifier.
