For many decades, hybrid devices have been used to connect 2-wire local circuits and 4-
wire long distance circuits in telephone lines. This leads to a weIl known problem, whereby …

Telecommunication systems and human-machine interfaces start employing multiple
microphones and loudspeakers in order to make conversations and interactions more …

A unified view of algorithms for adaptive transversal FIR filtering and system identification
has been presented. Wiener filtering and stochastic approximation are the origins from …

A stereo teleconferencing system provides a more realistic presence compared to monaural
systems. It helps listeners distinguish who is talking at the other end by means of spatial …

Stereophonic acoustic echo cancellation (SAEC), has been studied since the early 1990s.
Because of spatial realism, two‐channel audio is now becoming more interesting in a …

In this paper, we present a distributed affine projection (AP) algorithm for an acoustic sensor
network where the nodes are acoustically coupled. Every acoustic node is composed of a …

The article reviews, with technical depth, the history of research in audio and
electroacoustics, including electroacoustic devices, noise control, echo cancellation, and …

This chapter provides an introduction to adaptive signal processing, covering basic
principles through the most important recent developments. After a brief example for, we …

Stereophonic sound becomes more and more important in a growing number of applications
(such as teleconferencing, multimedia workstations, televideo gaming, etc.) where spatial …

Stereophonic acoustic echo cancellation has been found more difficult than echo
cancellation in mono due to a high correlation between the two audio channels. Different …
