Digital waveguides are generalized to the multivariable case with the goal of maximizing generality while retaining robust numerical properties and simplicity of realization. Multivariable complex power is defined, and conditions for “medium passivity” are presented. Multivariable complex wave impedances, such as those deriving from multivariable lossy waveguides, are used to construct scatteri...

This paper describes the long-distance reproduction of professional-level piano performance by transmission of redundant indexed UDP packets containing MIDI data over the Internet. Our project was developed with the express intent of enabling remote instruction of piano Master Classes where highly accurate and subtle musical gestures must be reproduced. With MIDI grand pianos on both ends of a ...

A real-time virtual audio reality model has been created. The system includes model-based sound synthesizers, geometric room acoustics modeling, binaural auralization for headphone or loudspeaker listening, and high-quality animation. The design goals of the overall project have been to create a virtual musical event that is as authentic as possible both in terms of audio and visual quality. No...

In this paper we present a new method for the decomposition of musical sounds into causal and anticausal contributions. The algorithm is based on a particular separation of zeros of the Z-Transform (ZZT) of signal frames, currently used in speech processing for glottal source parameters estimation. Acoustics of two particular continuous interaction instruments (CII) – trumpet and violin – is di...

Modal representations have been used successfully in the context of musical sound synthesis based on linear and time-invariant physical models. It is also particularly simple, from such a representation, to deduce estimates of computational complexity in a discrete time simulation from modal density: the operation count, as well as memory requirements may be related directly to the audio sample...

This paper presents the results of a study on quadruple flutes (multiple pipes) from UNESCO World Heritage Centre Teotihuacan, Mexico, based thorough examination fragmented, restored and partly reconstructed archaeological finds manufacture subsequent test series playable reproductions with refined reconstructive design. For latter, organological features, such as diameter, number position fing...
