Original Kurzfassung:
Recent advances in real-time music score following have
made it possible for machines to automatically track highly
complex polyphonic music, including full orchestra performances. In this paper, we attempt to take this to an
even higher level, namely, live tracking of full operas. We
first apply a state-of-the-art audio alignment method based
on online Dynamic Time-Warping (OLTW) to full-length
recordings of a Mozart opera and, analyzing the tracker?s
most severe errors, identify three common sources of problems specific to the opera scenario. To address these, we
propose a combination of a DTW-based music tracker with
specialized audio event detectors (for applause, silence/noise,
and speech) that condition the DTW algorithm in a topdown fashion, and show, step by step, how these detectors add robustness to the score follower. However, there
remain a number of open problems which we identify as
targets for ongoing and future research
