Karlheinz Brandenburg and Mark Kahrs With the advent of multimedia, digital signal
processing (DSP) of sound has emerged from the shadow of bandwidth limited speech …

In speech communication systems, such as voice-controlled systems, hands-free mobile
telephones, and hearing aids, the received microphone signals are degraded by room …

Interactive systems, virtual environments, and information display applications need
dynamic sound models rather than faithful audio reproductions. This implies three levels of …

Scattering-based numerical methods are increasingly applied to the numerical simulation of
distributed time-dependent physical systems. These methods, which possess excellent …

Modern graphics processing units (GPUs) are massively parallel computing environments.
They make it possible to run certain tasks orders of magnitude faster than what is possible …

Background A musical instrument should be" alive" in the hands of the performer. A
performance is naturally an interaction between the player and the instru-ment. While the …

The feedback delay network (FDN) has been proposed for digital reverberation, The digital
waveguide network (DWN) is also proposed with similar advantages. This paper notes that …

This article gives an overview of selected developments in musical sound synthesis based
on physical models of musical instruments–sometimes called “virtual acoustic” sound …

Due to recent increases in computing power, room acoustics simulation in 3D using time
step** schemes is becoming a viable alternative to standard methods based on ray …

The digital waveguide mesh has been an active area of music acoustics research for over
ten years. Although founded in 1-D digital waveguide modeling, the principles on which it is …
