Modeling the statistics of the violin

? Model the process, not a realization of the process!

• Time domain violin signal
  • instance of the wave-form is not controlled by the player.
  • phase is neither perceivable nor predictable.
    ? model does not generalize with respect to the control input.

• Short-term power spectrum of the signal
  • spectral characteristics are controlled by the player.
    ? generalizes with respect to the control input.
