Encoding Performance Data in MEI with the Automatic Music Performance Analysis and Comparison Toolkit

This paper presents a new method of encoding performance data in MEI using the recently added \texttt{<extData>} element. Performance data was extracted using the Automatic Music Performance Analysis and Comparison Toolkit (AMPACT) and encoded as a JSON object within an \texttt{<extData>} element linked to a specific musical note. A set of pop music vocals has was encoded to demonstrate both the range of descriptors that can be encoded in <extData> and how AMPACT can be used for extracting performance data in the absence of a fully specified musical score.
