Time stretching

• Sound board model does not represent physical partials and change characteristics even if stretched only weakly

  Reason: stretching of the high number of short partials results change nosiy characteristics into tonal characteristics $\Rightarrow$ other stretching approach?

• After considerable time stretching (factor of 10) the string model change characteristics, too.

  Reason: Representation of partials of multiple piano strings with only one set of harmonic partials?

Note: You can play all sounds by clicking on the time signal!
