Title
Score Following for Piano Performances with Sustain-Pedal Effects.
Abstract
One challenge in score following (i.e., mapping audio frames to score positions in real time) for piano performances is the mismatch between audio and score caused by the usage of the sustain pedal. When the pedal is pressed, notes played will continue to sound until the string vibration naturally ceases. This makes the notes longer than their notated lengths and overlap with later notes. In this paper, we propose an approach to address this problem. Given that the most competitive wrong score positions for each audio frame are the ones before the correct position due to the sustained sounds, we remove partials of sustained notes and only retain partials of “new notes” in the audio representation. This operation reduces sustain-pedal effects by weakening the match between the audio frame and previous wrong score positions, hence encourages the system to align to the correct score position. We implement this idea based on a state-of-the-art score following framework. Experiments on synthetic and real piano performances from the MAPS dataset show significant improvements on both alignment accuracy and robustness.
