A percussionist can alter the harmonic content of a tunable acoustic drum to provide a desired sound. By analysis of different aspects in construction of a drum the specific sound can be implemented. Through a Fast Fourier Transform of electronically acquired audio data an analysis of a drum can be performed at many stages of its construction. By dissecting the drum construction into various la...

At ICAD'96, a real-time virtual audio reality model was presented, which included model-based sound synthesizers, geometric room acoustics modeling, binaural auralization for headphone and loudspeaker listening, and high-quality animation. The DIVA environment is an integrated implementation of a virtual reality system currently aiming at a virtual symphony orchestra performance. In the current...

In this article, we present the current state of art in binaural audio with focus on head-related transfer functions (HRTFs) and valuation methods virtual acoustics descriptive attributes. This combination provides a methodology, which delivers basis for research studies reality (VR) individual non-individual functions. Based largely explored localization perception static signals, review offer...

The problem of the rigid-piston radiator mounted in an infinite baffle has been studied widely for tutorial as well as for practical reasons. The resulting theory is commonly applied to model a loudspeaker in the audio-frequency range. A special function, the Struve function H1 (z), occurs in the expressions for the rigid-piston radiator. This Struve function is not readily available in program...

Digital equalisation of room acoustics based on inverse filtering of measured response functions, introduces a number of theoretical and practical challenges. To overcome such problems, inverse filtering based on modified measured responses is proposed, derived via their complex Transfer Function smoothing, so that the processed responses are more perceptually compliant, of lower order and less...

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 ...

This review paper discusses the literature on perception and synthesis of environmental sounds. Relevant studies in ecological acoustics and multimodal perception are reviewed, and physicallybased sound synthesis techniques for various families of environmental sounds are compared. Current research directions an d open issues, including multimodal interfaces and virtal environments, automatic r...

Auralization and binaural technology is a strongly growing field in acoustics and audio signal processing [1]. Measurements and models of head-related transfer functions (HRTF) of human subjects or dummy heads are the source of information for the research of auralization and spatial hearing (see, e.g., [2], for a good review on these subjects). The information contained in HRTFs measured at va...

Our work is dealing with alternative interaction modes for visually impaired and blind people to use computers. The aim of the proposed approach is to exploit the human hearing capabilities to a better degree than this is done by customary screen-readers. A surrounding, three-dimensional audio interface is potentially increasing the information flow between a computer and the user. This paper p...
