Simulation and spectral analysis of inharmonic tones of musical instruments
Varsha Shah, Rekha S. Patil · International Conference on Signal Processing · 2008
Simulation and spectral analysis of harmonic and inharmonic pure tones of musical instruments is undertaken. It is shown how the basic wave such as sine can be used to simulate various harmonic and inharmonic sound signals of different instruments generating different timbres. It is shown that even the modest value of inharmonicity coefficient is sufficient to raise the frequency of inharmonic spectrum by a partial step more than that of the harmonic spectrum thus deviating the spectrum from strictly harmonic case. Listening tests of the simulated tones are also conducted which proves that the perception of inharmonicity depends on the number of partials present in the sound.
