In this paper, we present a digital method to simulate the effect of dynamic geometry modification of a simplified clarinet bore induced by tonehole closing or opening. For this purpose, we first consider a physical tonehole model where the closing of the hole is achieved by progressively reducing its radius. In the context of real-time synthesis of woodwind instrument tones obtained from digit...

Electronic pickup systems for acoustic instruments are often used in popular and contemporary music performances because they allow amplification and modification of a clean and direct signal. Strain gauge sensors on saxophone and clarinet reeds have been shown to be a useful tool to gain insight into tongue articulation during performance but also capture the reed vibrations. In our previous d...

The acoustic behaviour of wind instruments is largely determined by their acoustic impedance spectrum measured at the embouchure or 'input' to the instrument. The acoustic impedance Z is the ratio of acoustic pressure p U and its extrema identify the frequencies of resonances and antiresonances due to standing waves in the bore. (For example see [1].) Backus [2] reports measurements of the acou...

Musical timbre is a phenomenon of auditory perception that allows the recognition musical sounds. The challenging task because instrument or sound source complex and multifaceted influenced by variety factors, including physical properties source, way it played produced, recording processing techniques used. In this paper, we explore an abstract space with 7 dimensions formed fundamental freque...

In previous work, the authors presented a generalized parametric model of a pressure controlled valve, allowing the user to design a continuum of reed configurations, including “blown open”, “blown closed” and the “swinging door”. Though the generalized reed model behaved as expected, the quality of the produced sound was somewhat limited, likely due to the dependence of reed oscillation on the...

For the Schumacher model and Adachi–Sato model, which are effective physical models of wind instruments, present study introduces a more precise sound field expression using three-dimensional wave equation, instead one-dimensional analytical solutions instrument bore. The around bell section is expressed by normally differentiated Kirchhoff–Huygens formula, then boundary element method applied ...
