Active control of sound and vibration is a relatively new and fast growing field of research
and application. The numbers of papers published on the subject have been more than …

Modern systems for acoustic man-machine communication, such as teleconferencing
equipment or speech dialog systems, will have to provide hands-free voice interfaces with …

In this paper, we present an efficient real-time implementation of a broadband algorithm for
blind source separation (BSS) of convolutive mixtures. A recently introduced generic BSS …

Adaptive filtering based feedback cancellation is a widespread approach to acoustic
feedback control. However, traditional adaptive filtering algorithms have to be modified in …

We propose a method for nonlinear residual echo suppression that consists of extracting
spectral features from the far-end signal, and using an artificial neural network to model the …

The frequency-domain adaptive filter (FDAF) is widely used in echo cancellation systems
due to its low complexity and fast convergence rate. However, the FDAF algorithm with a …

In this chapter, we develop an analytical top-down approach to the problem of blind
dereverberation of speech and audio signals based on TRINICON (TRIple-N Independent …

Acoustic echo cancellation (AEC) is significantly more challenging in the case of
multichannel reproduction compared to the single-channel case. This is mainly due to the so …

While the semi-blind source separation-based acoustic echo cancellation (SBSS-AEC) has
received much research attention due to its promising performance during double-talk …

Echo cancelers typically employ control mechanisms to prevent adaptive filter updates
during double-talk events. By contrast, this paper exploits the information contained in time …
