Automatic Synchronization between Audio and Partial Music Score Representation.

In this paper we propose an algorithm namely ParSi (Partial Synchronization) which aligns different PCM executions with a partial music score representation. Generally, most synchronization algorithms require a complete score representation; despite of them, our algorithm is able to synchronize different PCM audio executions with a partial music score codified in MIDI. Therefore, only one MIDI instrument -chosen by user- is used during audio-score alignment. The audio analysis is performed using a notch filter. A set of conveniently parameters are used during the decisional phase. The analysis of synchronization results is provided. It shows we can have a good automatic synchronization even if just a partial score is available. [ABSTRACT FROM AUTHOR]
