Computer Optimization of Brass Wind Instruments
Computer optimization of brass wind instruments combines knowledge in several different areas. Usually the performance of those instruments is described by musical terms. Characteristics like intonation, response, pitch variability, sound timbre or efficiency have first to be objectified and mapped to acoustical properties which can be measured and properly predicted by computer simulation.
متن کاملNumerical Techniques for Acoustic Modelling and Design of Brass Wind Instruments
Preface. When H. Bouasse published his Instrumentsà Vent in two volumes in 1929–30, he set the starting point for what can be regarded as modern research on musical acoustics. Some 40 years later, the stock of published papers could be counted in their hundreds. However, it is only during the last two or three decades that our physical understanding, in combination with the development of compu...
متن کاملModelling the Wall Vibrations of Brass Wind Instruments
The vibration of the walls of brass wind instruments has been a subject of study in the field of musical acoustics throughout the last decades. The amplitude of such vibrations, stimulated by the oscillating air pressure inside the instrument bore, is very small compared to the dimensions of the instrument. However, it has been recently shown that at the flaring regions of the bell of brass ins...
متن کاملExtending Brass & Woodwind Instruments with Acoustic-Aggregate-Synthesis
This article discusses progress and advances in the Acoustic-Aggregate-Synthesis project (first described in Proceedings from ICMC, 2012). Acoustic-Aggregate-Synthesis is a real-time performancetool which fuses synthetic and acoustic sound sources in order to achieve semi-acoustic re-synthesis of a pre-defined acoustic model. This technology functions most effectively, from a cognitive stand-po...
متن کاملAcoustic pulse reflectometry for the measurement of musical wind instruments
The bore profile and input impedance of a musical wind instrument provide valuable information about its acoustical properties. The time domain technique of acoustic pulse reflectometry can be used to measure the input impulse response of a tubular object, such as a wind instrument, from which both its bore profile and input impedance can be calculated. In this thesis, after a discussion of the...
