Estimating room impulse responses (RIRs) has a number of applications, including
personalized audio, analyzing and improving acoustic behavior of concert halls, listening …

This paper presents a robust acoustic echo cancellation (AEC) system in the short-time
Fourier transform (STFT) domain using adaptive crossband filters. The STFT-domain AEC …

In this paper, we propose a formal methodology for tuning the parameters of a single-
microphone speech enhancement system for hands-free devices. The tuning problem is …

Acoustic echo cancellation (AEC) is a fundamental requirement of signal processing to
increase the quality of teleconferences. In this paper, a system that combines the Laguerre …

This paper addresses the challenging scenario for the distant-talking control of a music
playback device, a common portable speaker with four small loudspeakers in close …

In this dissertation, we build a foundation for what we refer to as the system approach to
signal enhancement as we focus on the acoustic echo cancellation (AEC) problem. Such a …

This paper introduces an approach to cluster and suppress acoustic echo signals in hands-
free, full-duplex speech communication systems. We employ the instantaneous recursive …

In this work, we propose an optimization framework for tuning the parameters of a speech
enhancement system to maximize its performance while constraining its computational …

Given the widespread use of miniaturized audio interfaces, echo control systems are faced
with increasing challenges to address a large variety of acoustic conditions observed by …

The trend in media consumption towards streaming and portability offers new challenges
and opportunities for signal processing in audio and acoustics. The most significant …
