In the following, real and synthetic sustain pedal impulse responses are presented. The impulse response of a Steinway grand piano Model C was obtained by hitting the bridge with an impulse hammer. Resynthesized version is computed by convolving the recorded impulse hammer force with the impulse response of the designed parallel bank of resonators.

Three recorded example tones (C2, C4, and C6) are played first without the sustain pedal, then with the synthetic sustain pedal, and finally with real sustain pedal:

[ (1) no sustain pedal --- (2) synthetic sustain pedal --- (3) real sustain pedal ]

Synthetic tones (C2, C4, and C6), which were generated with a physics-based model, are processed with the proposed sustain-pedal algorithm. First the tone without the sustain pedal is played, and then the same tone is played with the sustain pedal:

[ (1) synthetic tone without sustain pedal --- (2) synthetic tone with sustain pedal ]

A synthetic C major chord is played in arpeggio style with the synthetic sustain pedal.
