calcimpy

Input impedance calculation for air column ( wind instrument ) by python.

Plan

This is going to be new python programs written from scratch.

Dependancy

Python3, Numpy, Scipy, Pandas, Numba.

Documentation

1. Basics : Basic concept of caclimpy.

2. Webster equation memo : Simple memo about Webster equation for basic calculation of input impedance.

3. Loop impedance memo : Simple memo about impedance lcalculation of looped multi-column.

Sample and examples

sample/ Some simple sample XMEN files.

practice/ Example of calculation and its study (jupyter notebooks).

Programs

calcimpy.py CUI program for input impedance calculation of given XMEN file.

calcprs.py CUI program for calculation of pressure along with mensur.

printmen.py CUI program for printing XMEN file. Converting to L, D data can be done.

xmensur.py Module for handling XMEN file.

imped.py Module for calculation subroutines.

impcore.py Numba powered core routine for imped.py
