Tracing the reverberation lag in the hard state of black hole X-ray binaries [PDF]
, 2015 We report results obtained from a systematic analysis of X-ray lags in a sample of black hole X-ray binaries, with the aim of assessing the presence of reverberation lags and studying their evolution during outburst.

Reverberation suppression algorithm for LS beamforming based on Wiener post-filter
Dianzi Jishu Yingyong, 2018 Reverberation causes speech signal time and frequency to blur, and speech is difficult to understand when serious. In order to improve the speech quality, this paper presents a least squares beamforming reverberation suppression algorithm with Wiener ...

Noise-robust blind reverberation time estimation using noise-aware time-frequency masking [PDF]
arXiv, 2021 The reverberation time is one of the most important parameters used to characterize the acoustic property of an enclosure. In real-world scenarios, it is much more convenient to estimate the reverberation time blindly from recorded speech compared to the traditional acoustic measurement techniques using professional measurement instruments.

An Evaluation of Three-Stage Voice Conversion Framework for Noisy and Reverberant Conditions [PDF]
arXiv, 2022 This paper presents a new voice conversion (VC) framework capable of dealing with both additive noise and reverberation, and its performance evaluation. There have been studied some VC researches focusing on real-world circumstances where speech data are interfered with background noise and reverberation. To deal with more practical conditions where no
