The Complete Classical Music Companion v0.9

We present a first integrated prototype towards our long-term goal of building a complete classical music companion. When listening to a live performance of classical piano music, our system is able to almost instantly identify the piece that is being played, and the position within the piece. It then tracks the performance via an accurate and robust score following algorithm and shows the sheet music accordingly. Furthermore, the system continuously re-evaluates its current position hypotheses within a database of scores (roughly 1,000,000 notes!) and is capable of detecting arbitrary 'jumps' by the performer (e.g., leaving out repetitions, re-starts at any position, etc.) - not only within a piece, but within the complete database of classical piano scores.
