Seminar at Speech, Music and Hearing:

Physics-based modeling of the piano

Heidi-Maria Lehtonen, Department of Signal Processing and Acoustics, Helsinki University of Technology, TKK

Abstract

Digital pianos have become increasingly popular among consumers, offering excellent sound quality and many practical features like always being well tuned. The predominating sampling technique is, however, not suitable for all applications of piano synthesis, e.g. mobile devices and games, since it requires a large database from which tones are played back. Physics-based modeling avoids database constraints and gives better controllability in performance. The presentation gives an overview of research related to the piano that has been conducted during the past four years at the Dept. of Signal Processing and Acoustics, TKK. Topics discussed include digital waveguide modeling of string motion, dispersion due to string stiffness, multiple decay from coupled strings, beating effects, and modeling of the influence of the sustain pedal.
