This work extends previous research on numerical solution of nonlinear systems in musical acoustics to the realm of nonlinear musical circuits. Wave digital principles and nonlinear state-space simulators provide two alternative approaches explored in this work. These methods are used to simulate voltage amplification stages typically used in guitar distortion or amplifier circuits. Block level...

The codings of speech and music are different and in some ways complementary. The voice operates on acoustical principles distinctly different from those of (other) musical instruments. This paper explains how and poses the question: are the different codings the result of the different acoustics, or vice versa? What if the instruments came first? This paper develops the conjecture that the pit...

This work discusses the Hellenistic origin of some concepts underlying modern harmonic science. The framing ancient works in a long-term perspective allows us to highlight with particular evidence drastic cultural break, which occurred around middle second century B.C., following important conceptual tools for theoretical modeling musical acoustic phenomena, such as coincidences, resonances and...

AcMus is an integrated software platform for musical room acoustics. A preliminary version of the software was developed as a MATLAB prototype of acoustical analysis functions. The prototype processes measurements recorded from a room and outputs calculations that help us assessing the quality of the room for musical performance. We have measured a number of musical rooms ourselves and are curr...

This article contains a description of rules controlling the singing synthesis at the Department of Speech Communication and Music Acoustics at the Royal Institute of Technology (KTH) in Stockholm. In our research, synthesis of singing has played an important part for a long period of time. The rules controlling the singing synthesiser MUSSE DIG are implemented in a programming environment orig...

Acoustics in the 1850s combined listening, observation and notation. This was “real-time”, catching any phenomenon as it appeared. If it was repeatable, one could prepare for it. Continuous data rather than observation data enabled a very different analysis from observation and notebooks. Édouard-Léon Scott’s invention of the phonautograph enabled this. A surface moved below a stylus that was v...

The functioning of the first type, the flue or labial pipe, was already investigated within previous extensive research projects. The second pipe type, the reed pipe, is less often installed in pipe organs, and only little research was done in this field so far. This is why this pipe type is now the focus of research of the working group ‚Musical Acoustics ‘ at the Fraunhofer Institute for Buil...

This abstract describes a submission of the ThinkIT Speech Lab at Institute of Acoustics, Chinese Academy of Sciences to the onset detection contest of the Music Information Retrieval Evaluation eXchange (MIREX) 2006. This submission presents an algorithm using spectral flux to detect musical onsets. Firstly, a detection function is generated via spectral flux. Then, a peak picking procedure is...
