Physical Modeling Synthesis of the Recorder

Hiroko Terasawa $<$hiroko at ccrma$>$ (CCRMA)

Hi,

In the DSP seminar tomorrow, I will be presenting about physical modeling synthesis of recorder sound, which I worked on last year, and which I will present in ASA Nashville meeting next week. It will be a short presentation (3:30 - 3:50). Please drop in if interested. Your feedback will be greatly appreciated!

Thank you, - Hiroko

-- ABSTRACT --

A time-domain simulation of the soprano baroque recorder based on the digital waveguide model (DWM) and an air reed model is introduced. The air reed model is developed upon the negative acoustic displacement model (NADM), which was proposed for the organ flue-pipe simulation [Adachi, Proc. of ISMA 1997, pp. 251-260], based on the semiempirical model by Fletcher [Fletcher and Rossing, The Physics of Musical Instruments, 2nd ed. (Springer, Berlin, 2000)]. Two models are proposed to couple DWM and NADM. The jet amplification coefficient is remodeled for the application of NADM for the recorder, regarding the recent experimental reports [Yoshikawa and Arimoto, Proc. of ISMA 2001, pp. 309-312]. The simulation results are presented in terms of the mode transient characteristics and the spectral characteristics of the synthesized sounds. They indicate that the NADM is not sufficient to describe the realistic mode transient of the recorder, while the synthesized sounds maintained almost resemble timbre to the recorder sounds.

Today, after Hiroko presents her upcoming ASA talk, Eric Lindemann will talk about his generalized sampling synthesis based on reconstructing phrase segments. Then after that, Arvindh Krishnaswamy will talk about his recent experience with nonlinear string synthesis algorithms. - Julius
