Music Signal Spotting Retrieval by a Humming Query Using Model Driven Path Continuous Dynamic Program

摘要

In this paper the authors propose a search method for finding within various time series for acoustic analysis patterns for music the similar periods in a search query consisting of a time series of pitch differences (intervals) extracted from humming. The proposed method (model driven path Continuous Dynamic Programming) is an extension of continuous DP which allows for spotting searches and has the benefit of having the time series for the reference model directly identify the form of the slope limitations used in continuous DP. In this paper the authors perform humming query experiments for 20 songs of popular music and demonstrate the effectiveness of their proposed method.
