Automatic Music Synchronization Using Partial Score Representation Based on IEEE 1599

Abstract

This article proposes the new algorithm ParSi, for Partial Synchronization, which aligns different PCM executions with a partial music score representation. While in general most synchronization algorithms require a complete score representation, this 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 needed for audio-score alignment. The MIDI file is selected by taking into account the related IEEE 1599 file. Audio analysis is performed using a notch filter. A set of convenient parameters is used during the decisional phase. Analysis of synchronization results is provided, showing that it possible to have a good automatic synchronization, even if just a partial score is available.
