CSDT Work Monday 6/20-Sunday 6/26

Monday 6/20 9:15am-12:15pm:
  • From last Friday, calculated fractal dimension was not matching input fractal dimension
    • This is because analysis was being limited to a certain frequency range within the whole power spectrum
    • Analysis of whole power spectrum confirms calculated fractal dimension equals input fractal dimension
  • Produced graphs of various known power distributions

Tuesday 6/21 9:30am-12:45pm:
  • Measured processing time for analysis script for audio samples with various numbers of datapoints
  • Found processing time increased quadratically with number of datapoints
    • Nearly all time spent on calculating instantaneous pitch
  • Tested ways of decreasing processing time
  • Worked on computing instantaneous pitch in parts and concatenating

Wednesday 6/22 10:15am-11:00am, 12:30pm-3:45pm:
  • Continued work on computing instantaneous pitch piecewise
  • Attended weekly team meeting
  • Last week's goals accomplished up to loading the entire classical piece
    • Need to edit script to allow loading audio piecewise
  • Goals for next week:
    • Today, Thursday:  Finish editing script to process pitch of long audio files by breaking into parts
    • Friday: Minimize processing time for algorithm; analyze 7 minute classical piece
    • Monday: Repeat some of the analysis done in Professor Eglash's paper
      • Analyze several samples of poetry reading, prose reading, and a Capella music
      • Chart fractal dimension for each sample
    • Tuesday: Analyze rhythm produced using CSDT rhythm wheels
    • Wednesday (6/29): Prepare for meeting
Thursday 6/23, 10:00am-3:00pm:
  • Compiled photos, arc coordinate printouts, and screenshots from teaching Anishinaabe Arcs at Albany Boys and Girls club into zip archive
  • Finished script for analyzing wave files piecewise
    • Need to read the file piecewise
    • Script run time based amount of data Matlab has in workspace (not necessarily in scope)
  • Corrected fractal dimension calculation
Friday 6/24, 12:00pm-12:30pm, 3:30pm-5:45pm
  • Optimized script to find size of pieces to use to minimize run time
  • Tested script on known fractal dimension-audio and short Mozart audio clip
