Automatic Optimization of a Musical Similarity Metric Using Similarity Pairs

With the growing amount of multimedia data available everywhere and the necessity to provide efficient methods for browsing and indexing this plethora of audio content, automated musical similarity search and retrieval has gained considerable attention in recent years. This paper presents a system which combines a set of perceptual low-level features with appropriate classification schemes for the task of retrieving similar sounding songs in a database. A methodology for analyzing the classification results to avoid time consuming subjective listening tests for an optimum feature selection and combination is presented. It is based on a calculated "similarity index" that reflects the similarity between specifically embedded similarity pairs. The system’s performance as well as the usefulness of the analyzing methodology is evaluated through a subjective listening test.
