In answer to Richard's question, Denis Brassard writes: >>>>> One equation used to find the frequency of a note is the following: I took the next 2 formulas from Dr. Albert Sanderson: (1.b) I=Bn^2 B is the inharmonicity constant and n is the partial number. <<<<< From my own empirical studies, I have found that the n^2 term in the equation for inharmonicity does not agree with actual measurements. I suggest using, instead of n^2, the following lookup table: n C[n] (instead of n^2) -------------- 1 1.000 2 4.000 3 8.450 4 13.18 5 19.72 6 27.27 7 35.53 8 46.25 9 57.12 10 69.43 11 83.22 12 96.60 13 109.8 14 125.4 15 139.5 16 156.1 This is, in fact, what is used by TuneLab Pro and TuneLab Pocket. -Robert Scott Real-Time Specialties
