We present a framework to provide a quantitative representation of aspects of musical sound that are associated with musical expressiveness and emotions. After a brief introduction to the background of expressive features in music, we introduce a score to audio mapping algorithm based on dynamic time warping, which segments the audio by comparing it to a music score. Expressive feature extraction...
Musical instruments, both acoustic and electronic, can be implemented as human control interfaces for electronic game applications. The control parameters are extracted from instrument performances and further mapped to game control parameters. The authors also illustrate the details of response feedback and provide a summary.
In this paper we present a transcription method for polyphonic music. The short time Fourier transform is used first to decompose an acoustic signal into sonic partials in a time-frequency representation. In general the segmented partials exhibit distinguishable features if they originate from different ldquovoicesrdquo in the polyphonic mix. We define feature vectors and utilize a max-margin classification...
