Source-resonator approach (see section 1.)
Analysis and resynthesis of the vibration of single or multiple struck strings using single or coupled digital waveguides respectively (see section 2.2).
The original signals (velocity signals) are measured on the experimental setup (see section 2.4), using an accelerometer at the bridge.
One string
The original signals (velocity signals) are measured on the piano (see section 2.5), using an accelerometer at the bridge.
Excitation signal obtained by deconvolution for three different hammer velocities (see figure 12)
Static spectrum and error term (see section 3.2.1)
Synthesis of the vibration of a single struck string using single digital waveguide and the excitation model for three different hammer velocities. The original signals (velocity signals) are measured on the experimental setup, using an accelerometer at the bridge.
