Monday 6/6 11:00am-12:15pm, 3:30-5:00pm:
- Completed Matlab script to plot best fit line with Power Series of Amplitude and display slope
- Helped teach Arcs applet to Boys and Girls Club in Albany
- Students constructed circular wigwams
- Located points on life-sized grid (outside)
- Attached saplings to grid using ties through holes drilled in saplings
- Students seemed more comfortable with finding points on graph
- Knew if given (-4,3), would have to move 4 in one direction and 3 in another from (0,0)
- Often did not distinguish between x and y and positive and negative, especially for 3rd and 4th grade
- Students enjoyed building wigwam
- Offered an impromptu lesson on finding area using life-sized grid
Tuesday 6/7 10:10-10:40am:
- Began researching methods for finding instantaneous pitch of audio signal
- Aim is to find power series of pitch
- Analyze various musical genres and other audio building on Voss and Clark work (Nature, Vol 258 Nov. 1975, p. 317-318)
Wednesday 6/8 10:20-10:50am, 1:30-3:15pm:
- Continued researching methods for finding instantaneous pitch
- Did not find any algorithms for using solely zero-crossing
- Began testing algorithm using "subharmonic to harmonic ratio" (geared towards speech)
- Attended weekly planning/review meeting
- Goals for next week:
- Tues 6/14: Research pitch-detection algorithms
- Wed: Test algorithms and compare performances; prepare for meeting
- Thurs: Help compile report on teaching Anishinaabe Arcs at Albany Boys and Girls Club
- Fri: Successfully compute instantaneous pitch of short audio clip using chosen method
- Mon: Load longer (~7 min) classical composition piecewise into Matlab;
- Compute amplitude power series
- Compute instantaneous pitch
- Tues: Catch up; prepare for meeting
- Next goal: compute power series of instantaneous pitch
