Abstract [en]

A system is described that aims to modify the performance of a musical recording (classical music) by changing the basic performance parameters tempo, sound level and tone duration. The input audio file is aligned with the corresponding score, which also contains extra information defining rule-based modifications of these parameters. The signal is decomposed using analysis-synthesis techniques to separate and modify each tone independently. The user can control the performance by changing the quantity of performance rules or by directly modifying the parameters values. A prototype Matlab implementation of the system performs expressive tempo and articulation modifications of monophonic and simple polyphonic audio recordings.
