prerequisites: pyyaml sounddevice soundfile pthon-rtmidi

export PYTHONPATH=${HOME}/src/picadae/control/app python p_ac.py -c p_ac.yml

Data collection

Record a sequence of notes of decreasing dynamic level

python p_ac.py # start the interactive data collection program

Capture note 60 and 61 using the full_pulseL[] and holdDutyPctD{} from the p_ac.yml

c 60 61

python plot_seq_1.py p_ac.yml ~/temp/p_ac_3_od manual_db

Interpolate across the min and max db values to form the min/max curves for the complete set of keys. The anchor points for the curves are taken from cfg record manuMinD,manualAnchorPitchMinDbL, and manualMaxDbL.

      # select the event (takeId, eventIdx) to use to represent the min value for each pitch
      manualMinD: {
        36: [2, 10],
        48: [2, 10],
        60: [2, 10],
        72: [2, 10],
        84: [2, 10]
        },

      # leave 60 out of the min anchor point list
      manualAnchorPitchMinDbL: [ 36,48,72,84 ],
      
      manualAnchorPitchMaxDbL: [ 36,48,60,72,84 ],
