Adjust parameters for fipple reactance model based on new analysis of measurements.
Model whistle termination as an unflanged end, rather than flanged end.
Gives better correlation with measured results.
Adjust the ranges used for interpolating nominal frequencies at different blowing levels.
In particular, significantly lower the nominal frequency of the lowest note at low blowing levels.
Use tonehole TMM from Antoine's 2010 thesis, rather than 2012 JASA paper.
Gives better agreement with measurements.
Update test data to match revised measurements and tuning model.
