| MDFourier deserves to be far better known, and widely used.

| I am interested in characterizing the notes of a particular

| frequency of the note. Then repeat for every note. The goal is to
| understand how different build dimensions and materials for the
| instrument effect the frequencies of the notes.
|
| Obviously, I could just do a fourier transform on each recording.
| But I am wondering if there are specialized libraries or software
| that make this easier, or do other interesting calculations or
| visualizations that are currently in my unknown unknowns.
