Audio Signal Classification Using Support Vector Machines

Abstract

As the internet community grows larger, digital music distribution becomes widely available and is made easier than ever. Artists from all over the world can make their songs available by a single click. Websites, containing varieties of music style for download, charge only a fraction of the cost of a CD for the service. With the incredible amount of music pieces available, it is impossible to classify each piece by its style manually. A procedure is proposed using the support vector statistical learning algorithm to achieve the task autonomously. Digital music files are converted, partitioned and processed to obtain the desirable input vectors for the algorithm. As the machine learns the features of each music genre, it is capable of classifying input vectors from unknown pieces. A simulation was carried out to evaluate the efficiency of the algorithm. Results from the simulation are presented and discussed in this paper. Conclusions are drawn by comparing other algorithms against the proposed method.
