25   
26      This package is used for the calculation of the frequency response of wind 
27      music instrument. It is based on the discretization of instrument air  
28      columns into cylindrical and conical sections, with and without toneholes.  
29

41      The Instrument class and CalculateImpedance functions, defined in the Inst 
42      module, contains the core of the methode. The Waveguides, ToneHole, and 
43      Radiation modules implement the transmission matrices used in the 
44      calculation. Boundary layer losses are taken into account.
