Perceptual and Analytical Analysis of the effect of the Hammer Impact on the Piano Tones

This paper presents a model of the excitation corresponding to the hammer impact in a hybrid piano model. An experimental setup permits the measurement of the signal at the bridge location. The signal is separated into an excitation and resonant contribution. This work focuses on the modeling of the excitation part using both physical and perceptually relevant parameters. The resulting model can be used both in analysis/synthesis and transformation. Important piano performance parameters such as position and velocity of the hammer are inherent in the model.
