Robust acoustic source localization based on modal beamforming and time–frequency processing using circular microphone arrays
TL;DR: This paper presents a localization framework based on circular harmonics beamforming and T-F processing that provides accurate localization performance under very adverse acoustic conditions and discusses the validity of the proposed approach and comparing its performance with other state-of-the-art methods.
Journal ArticleDOI
An iterative approach to source counting and localization using two distant microphones
TL;DR: A time difference of arrival (TDOA) estimation framework based on time-frequency inter-channel phase difference (IPD) and an iterative contribution removal (ICR) algorithm that successfully solves the GCC peak ambiguities between multiple sources and multiple reverberant paths.

Junhyeong Pak,Jong Won Shin +1 more
TL;DR: A DNN-based phase difference enhancement for DoA estimation, which turned out to be better than the direct estimation of the DoAs from the input interchannel phase differences (IPDs).

Real-time multiple sound source localization and counting using a soundfield microphone
TL;DR: A multiple sound source localization and counting method based on a relaxed sparsity of speech signal that achieves a higher accuracy of DOA estimation and source counting compared with the existing techniques has higher efficiency and lower complexity, which makes it suitable for real-time applications.

Evaluation of generalized cross-correlation methods for direction of arrival estimation using two microphones in real environments
TL;DR: In this article, four generalized cross-correlation methods for localization of speech sources with two microphones have been analyzed in different real scenarios with a stationary noise source, and these scenarios have been acoustically characterized, in order to relate the behavior of these cross correlation methods with the acoustic properties of noisy scenarios.

Multiple emitter location and signal parameter estimation
TL;DR: In this article, a description of the multiple signal classification (MUSIC) algorithm, which provides asymptotically unbiased estimates of 1) number of incident wavefronts present; 2) directions of arrival (DOA) (or emitter locations); 3) strengths and cross correlations among the incident waveforms; 4) noise/interference strength.

Blind separation of speech mixtures via time-frequency masking
Ozgur Yilmaz,Scott Rickard +1 more
TL;DR: The results demonstrate that there exist ideal binary time-frequency masks that can separate several speech signals from one mixture and show that the W-disjoint orthogonality of speech can be approximate in the case where two anechoic mixtures are provided.

Robust Localization in Reverberant Rooms
TL;DR: This chapter summarizes the current field and comments on the general merits and shortcomings of each genre, and presents a new localization method that is significantly more robust to acoustical conditions, particularly reverberation effects, than the traditional localization techniques in use today.

TL;DR: A power weighted two-dimensional histogram constructed from the ratio of the time-frequency representations of the mixtures which is shown to have one peak for each source with: peak location corresponding to the relative amplitude and delay mixing parameters.
