The Automated Music Performance Analysis and Comparison Toolkit for the MATLAB programming environment automatically analzyes performance data from recordings where a score is available By using the information available in the score about what notes are expected in the performance and the order in which they occur.

AMPACT provides estimates of note onsets and offsets for tones with non-percussive onsets (e.g., vocalists) that are more robust than blind onset detection algorithms The alignment algorithm and the analysis portion of toolkit are be available in AMPACT Version 0.3. The analysis portion for monophonic audio includes the extraction of various performance parameters: inter-onset intervals between notes and tempo information; relative dynamic level between notes; mean frequency for each note and interval sizes in cents; vibrato rate and depth. For polyphonic audio, AMPACT produces estimates of onsets and offsets for all of the voices in notated simultaneities.
