A Coupled Duration-Focused Architecture for Real-Time Music-to-Score Alignment
Abstract--The capacity for realtime synchronization and coordination is a common ability among trained musicians performing a music score that presents an interesting challenge for machine intelligence. Compared to speech recognition, which has influenced many music information retrieval systems, music's temporal dynamics and complexity pose challenging problems to common approximations regarding time modeling of data streams. In this paper, we propose a design for a realtime music to score alignment system. Given a live recording of a musician playing a music score, the system is capable of following the musician in realtime within the score and decoding the tempo (or pace) of its performance. The proposed design features two coupled audio and tempo agents within a unique probabilistic inference framework that adaptively updates its parameters based on the realtime context. Online decoding is achieved through the collaboration of the coupled agents in a Hidden Hybrid Markov/semi-...
