How to improve the sound quality of the acoustic synthesis process?

The sound quality of the variable speed sound synthesis process of MANATEE software might be lower in case of spectral leakage in the signal.

For synchronous machines one should not have any spectral leakage. On induction machines in loaded conditions the leakage can be reduced by increasing the number of revolution Input.Simu.Nrev. The leakage is cancelled at no load condition of induction machines.

More realistic results are obtained by increasing the maximum frequency for the vibroacoustic model up to maximum audible frequency. By doing this, you also need to increase the time discretization (and therefore computation time) to keep meaningful results :

Input.Simu.freq_max_spec=20000;
