Analysis and synthesis of piano tone
Astrid Reinholdt, Erik Jansson, Anders G. Askenfelt · The Journal of the Acoustical Society of America · 1987
Signals from a grand piano, consisting of the string velocity and the sound in the room, were recorded. The signals were analyzed with regard to waveform and spectral development in time. The analysis, as well as a listening to the recording, revealed a prominent initial thump in the room signal that preceded the tonal string sound. This attack sound was not present in the string velocity signal. Piano tones were synthesized by modeling the analysis results in an additive computer synthesis. Important features in the synthesized piano tone, such as spectral envelopes, initial thump, inharmonicity in strings, and multiple stringing, are illustrated by sound examples.
