i-Ring: a system for humming transcription and chord generation

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 of i-Ring as a handy tool for computer assisted music composition for polyphonic ringtones
