The individual trials are combined into a single file for analysis in Mathematica:

pid9049-13.ma


Analysis Data

The absolute beat times in the music are extracted from pid9049-13.avg and stored in a plain text file. The following data is useful for generating clicktracks for the audio recording of the performance.

The average beat file pid9049-13.ma is missing.

Next, the offsets analyzed in Mathematica are added to each individual trial in another combined trial file for use in further analysis of the individual trials. The average values of the data in the following file whould give you the average performance times listed in the above file:

The combined file pid9049-13-abs.ma is missing.


Score Alignment Data

The beat times are first attached to the original score:

the file pid9049-13.btime is missing

Then the times of sub-beats are interpolated from the beat times:

the file pid9049-13.time is missing


Performance Analysis Data

Finally, the timing information for all individual notes in the score are extracted to a file for use in automatic note identification in an audio file of the performance:

the file pid9049-13.notes is missing

Where the columns represent the following information about a note:

  1. abstime -- average absolute time in milliseconds of human beats where the note is expected to be in the audio file.
  2. duration -- expected duration in milliseconds of the note based on score duration.
  3. note -- MIDI note number of pitch (60 = middle C, 61 = C-sharp/D-flat, etc.).
  4. metlev -- metric level of the note: 1 = occurs on a downbeat; 0 = occurs on another beat in the measure; -1 = occurs on an offbeat.
  5. measure -- The measure number in which note occurs.
  6. absbeat -- The absolute beat from starting beat at 0 for the first beat of the composition.
  7. mintime -- minimum absolute time of human tapping for this note.
  8. maxtime -- maximum absolute time of human tapping for this note.
  9. sd -- standard deviation of human tapping time in milliseconds.
