Parametric analysis, modeling, and equalization (inverse modeling) of reverberant and resonating systems find many applications in audio and acoustics. These include room and concert hall acoustics, resonators in musical instruments, and resonant behavior in audio reproduction systems. Estimating the reverberation time or the modal decay rate are important measurement problems in room and conce...

The IRCAM Musical Acoustics Team is not only focused on the musical instruments modelisation research but also on the computer implementation of these models and the evaluation of the musical interest that the computer implementation may have. The physical modelling sound synthesis software Modalys is an environment where virtual acoustical instruments may be imagined, performed and manipulated...

Traditionally, the average professional musician has owned numerous acoustic musical instruments, many of them having distinctive acoustic qualities. However, a modern musician could prefer to have a single musical instrument whose acoustics are programmable by feedback control, where acoustic variables are estimated from sensor measurements in real time and then fed back in order to influence ...

Recent research in physical modeling of musical instruments for purposes of sound synthesis is reviewed. Recent references, results, and outstanding problems are highlighted for models of strings, winds, brasses, percussion, and acoustic spaces. Emphasis is placed on digital waveguide models and the musical acoustics research on which they are based.

Choir acoustics is but one facet of choir-related research, yet it is one of the most tangible. Several aspects of sound can be measured objectively, and such results can be related to known properties of voices, rooms, ears and musical scores. What follows is essentially an update of the literature overview in my Ph.D. dissertation from 1989 of empirical investigations known to me that deal sp...

In the context of musical acoustics, physical models of musical instruments have to be more and more sophisticated. For string models, realism is obtained by taking into account tension, flexion, shear, rotation and coupling phenomena but also nonlinear effects due to large displacements. The sound synthesis modal method is extended to the nonlinear case using Volterra series. The inverse probl...

The paper attempts to give a contribution to the dynamic analysis of musical instruments through application of a multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena. The systematic organization of the multidisciplinary study proposed by MUSICOS and some preliminary results related to bowed instruments, with particular reference to viol...
