    In this article, alternative approaches to digital keyboard instrument synthesis are looked into. Physics-based sound synthesis, which aims at generating natural-sounding musical instrument tones algorithmically without using a large sample database, is a promising approach. It would provide high-quality music synthesis to systems that cannot afford a large memory, such as mobile phones and portab... View full abstract»

    This article focuses on modular, wave-based, discrete-time modeling of the resonator oscillations. The main advantage of using a wave-based approach is that it explicitly simulates the way in which waves build up in a real instrument and therefore inherently yields a spatial representation. The wave-based approach also happens to be computationally efficient, mainly due to the fact that lossless t... View full abstract»

    Direct numerical simulation methods have played a growing role, albeit a background one, in musical sound synthesis for some time now. Yet, they appear to be the most straightforward and general approach to physical modeling. For such general techniques applied to complex nonlinear systems, the problem of numerical stability lies on the horizon. This article has attempted to outline a more modern ... View full abstract»

    Block-based physical modeling is a methodology for modeling physical systems with different subsystems. It is an important concept for the physical modeling of real or virtual musical instruments where different components may be modeled according to different paradigms. Connecting systems of diverse nature in the discrete-time domain requires a common interconnection strategy. This contribution p... View full abstract»

    This paper introduces the concept of synthesis based on performance sampling. It explains that although sampling has been considered a way to capture and reproduce the sound of an instrument, it should be better considered a way to model the sonic space produced by a performer with an instrument. The paper presents a singing voice synthesizer, pointing out the main issues and complexities emerging... View full abstract»

    This article describes a new synthesis technology called reconstructive phrase modeling (RPM). A goal of RPM is to combine the realistic sound quality of sampling with the performance interaction of functional synthesis. Great importance is placed on capturing the dynamics of note transitions-slurs, legato, bow changes, etc. Expressive results are achieved with conventional keyboard controllers. M...

    Corpus-based concatenative methods for musical sound synthesis have attracted much attention recently. They make use of a variety of sound snippets in a database to assemble a desired sound or phrase according to a target specification given in sound descriptors or by an example sound. With ever-larger sound databases easily available, together with a pertinent description of their contents, they ... View full abstract»

    In this article, we outlined time-frequency techniques that, when brought together, form the basis for FAS. The method is based on an exact orthogonal transform, the HBWT. The FAS model can be seen as an intelligent spectrogram, i.e., as a spectrogram where the frequency bins (the HBWT subbands) are adapted to the spectrum of the analyzed sound by tuning the number of channels P to the period of t...

    In this article, oscillator algorithms for digital subtractive synthesis were reviewed. The algorithms were divided into three categories: bandlimited, quasi-bandlimited, and alias-reducing methods. In the first category, the most interesting methods are in practice those that utilize wavetable techniques. The second category consists of methods that low-pass-filter the underlying continuous-time ... View full abstract»

    Concert hall design is known to be a compromise between construction features (such as the architecture/shape of the hall and the number of seats) and sound qualities (such as the clarity, loudness, and reverberation). In this article, the physical properties of unamplified concert halls and their connection to the perception of music and reverberation by humans are discussed View full abstract»
