Original Kurzfassung:
The goal of real-time music tracking is to follow a musical
performance on-line and at any time report the current position
in the score. To achieve this, both the score and the
performance have to be represented in a suitable way. In
this paper, we first evaluate the performance of some wellknown
features and then propose a simple but effective distance
normalization strategy for onset-emphasized features,
which greatly improves the alignment results. Finally, we
combine both harmonic and onset-emphasized features in a
fashion known from off-line audio alignment, resulting in a
combination which outperforms each individual feature regarding
robustness and accuracy.
