In this paper, we describe the concept of music scene description and address the problem of detecting melody and bass lines in real-world audio signals containing the sounds of various instruments. Most previous pitch-estimation methods have had difficulty dealing with such complex music signals because these methods were designed to deal with mixtures of(More)
This paper describes the design policy and specifications of the RWC Music Database, a copyright-cleared music database (DB) compiled specifically for research purposes. Shared DBs are common in other research fields and have made significant contributions to progress in those fields. The field of music information processing, however, has lacked a common(More)
Current retrieval systems can handle tens-of-thousands of music tracks but new systems need to aim at huge online music collections that contain tens-of-millions of tracks. ABSTRACT | The steep rise in music downloading over CD sales has created a major shift in the music industry away from physical media formats and towards online products and services.(More)
This paper describes the design policy and specifications of the RWC Music Database, a music database (DB) that is available to researchers for common use and research purposes. Various commonly available DBs have been built in other research fields and have made a significant contribution to the research in those fields. The field of musical information(More)
A musical boundary is a transition between two musical segments such as a verse and a chorus. Our goal is to automatically detect musical boundaries using temporally-local audio features. We develop a set of difference features that indicate when there are changes in perceptual aspects (e.g., timbre, harmony, melody, rhythm) of the music. We show that many(More)
The statistical multipitch analyzer described in this paper estimates multiple fundamental frequencies (F0s) in polyphonic music audio signals produced by pitched instruments. It is based on hierarchic4al nonparametric Bayesian models that can deal with uncertainty of unknown random variables such as model complexities (e.g., the number of F0s and the(More)

This paper describes a method for obtaining a list of repeated chorus ("hook") sections in compact-disc recordings of popular music. The detection of chorus sections is essential for the computational modeling of music understanding and is useful in various applications, such as automatic chorus-preview/search functions in music listening stations, music(More)
