Virtual audio reality environments have in recent years become popular in such fields as computer music, acoustics, multimedia, and telecommunications [1]. There are often computational constraints that lead to very simplified systems that faintly resemble the physical reality. We present a distributed expandable virtual audio reality system that can accurately yet efficiently model room acoust...

For architects, real-time 3D visual rendering of CAD-models is a valuable tool. The architect usually perceives the visual appearance of the building interior in a natural and realistic way during the design process. Unfortunately this only emphasizes the role of the visual appearance of a building, while the acoustics often remain disregarded. Controlling the room acoustics is not integrated i...

Parametric analysis, modeling, and equalization (inverse modeling) of reverberant and resonating systems find many applications in audio and acoustics. These include room and concert hall acoustics, resonators in musical instruments, and resonant behavior in audio reproduction systems. Estimating the reverberation time or the modal decay rate are important measurement problems in room and conce...

MUSC 113. Live Audio Engineering. 3 Credits. This course covers fundamentals of live audio engineering, rudimentary acoustics, auditory perception and psychoacoustical concepts. Students will learn to assemble sound reinforcement systems for small and large ensembles and examine how sound is perceived by the human ear. Topics such as signal flow, cabling, mixing, busing and monitoring will be a...

This paper presents an ongoing project for augmenting acoustic instruments with active acoustics. Active acoustics are defined as audio-rate vibration driven into the instruments physical structure, inducing air-borne sound output. The instrument’s acoustic sound is thus doubled by an electronic soundscape radiating from the same source. The article is centered on a case study on two guitars, o...
