Automatic Music Performance Analysis & Comparison
Journal of New Music Research article published
An article entitled “Estimating Onset and Offset Asynchronies in Polyphonic Score-Audio Alignment" has been published in the Journal of New Music Research that describes the polyphonic algorithm available in AMPACT Version 0.3. The specific functions that implement this algorithm are: runPolyAlignment.mgenPolyTrans.m, and genMeansCovars.m.
