[Poster Presentation] Estimation of playing position from music and speech sources based on music database
Satoshi Inui, Toru Takahashi (OSU)
Abstract (in Japanese) (See Japanese page) 
(in English) We describe about music information retrieval (MIR) system in real environment. In the environment, music and non-music signals are simultaneously occurred by different points. We investigate that MIR system in the simplest real environment, where music and voice signals are simultaneously occurred by two different points. The system must identify music and estimate the position in the music from received signal that is mixture signal of music signal with voice signal. The proposed system uses sound source localization and separation techniques to capture the target music signal. Then, the most likely music and its position are estimated based on a similarity between the captured signal and entry in the predefined database. The similarity is defined by acoustic feature named binary chroma spectrum. We examine MIR performance of typical single channel based system and microphone-array based system. F-measure is calculated to evaluate performance of the systems. It is confirmed that microphone-array based system is outperform typical single channel based system. We conclude that binary chroma spectrum is suitable for sound source separation.
