Separation of voice and music is an interesting but difficult problem. It is useful for many other researches such as audio content analysis. In this paper, the difference between voice and music signals is carefully studied. It is proposed that the harmonic structure stability is the key difference between them. A separation algorithm based on this theory is proposed. The main idea is to learn the...
This paper describes the construction of a system called i-Ring that can generate a polyphonic ringtone based on a user's humming input. Algorithms used in the system for music transcription and chord generation include various techniques in speech and music signal processing, such as pitch tracking and dynamic programming, which are explained in the paper. Experimental results demonstrate the feasibility...
