Query-by-tapping systems are content-based music retrieval systems that allow users to tap or clap in a microphone the rhythmic pattern of the melody requested. In this paper, a new query-by-tapping system is described. This system is based on adaptations of alignment algorithms successfully applied for melodic similarity estimation. A similarity score is computed according to the cost of the elementary...
In analyzing polyphonic signals, the handling of overlapping partials is one important problem. The assumptions usually made for partial overlaps are the additivity of the linear spectrum or that of the power spectrum. In this study, the expected amplitude of two overlapping partials is derived based on the assumption that the partials overlap at the same frequency and the phase is uniformly distributed...
This paper suggests the application of the Receiver Operating Characteristics (ROC) graph to assess the performance of any speech/music discrimination method. ROC graphs are applied in the field of speech/music discrimination to assess the Time Series Events (TSE) method. The discrimination problem is viewed as two detection problems: detection of speech and detection of music. It was found that the...
This article describes how semantic Web technologies can be used to interlink musical data sources that have traditionally been isolated and difficult to integrate.
