We introduce a prototype of an educational web application
for comparative performance analysis based on source separation and object-based audio techniques. The underlying
system decomposes recordings of classical music performances
into note events using score-informed source separation and
represents the decomposed material using semantic web technologies. In a visual and interactive way, users can explore
individual performances by highlighting specific musical aspects directly within the audio and by altering the temporal
characteristics to obtain versions in which the micro-timing
is exaggerated or suppressed. Multiple performances of the
same work can be compared by juxtaposing and blending
between the corresponding recordings. Finally, by adjusting
the timing of events, users can generate intermediates of
multiple performances to investigate their commonalities and
di↵erences.
