We propose a time difference of arrival (TDOA) estimation framework based on time-
frequency inter-channel phase difference (IPD) to count and localize multiple acoustic …

In this paper, we consider the problem of joint direction-of-arrival (DOA) and fundamental
frequency estimation. Joint estimation enables robust estimation of these parameters in multi …

In this paper, the problem of joint multi-pitch and direction-of-arrival (DOA) estimation for
multichannel harmonic sinusoidal signals is considered. A spatio-temporal matrix signal …

This paper introduces a modification of phase transform on singular value decomposition
(SVD-PHAT) to localize multiple sound sources. This work aims to improve localization …

In this paper, spatio-temporal filtering methods are proposed for estimating the direction-of-
arrival (DOA) and fundamental frequency of periodic signals, like those produced by the …

The performance of conventional acoustic source localization and tracking system reduces
significantly when reverberation, noise, and acoustic interference are present. In this paper …

We introduce a new and intuitive algorithm to characterize and localize multiple harmonic
sources intersecting in the spatial and frequency domains. It jointly estimates their …

Traditionally, direction-of-arrival (DOA) and pitch estimation of multichannel, periodic
sources have been considered as two separate problems. Separate estimation may render …

The steered response power with phase transform weighted (SRP-PHAT) is a robust sound
source localization method based on microphone array. Multiple source localization has …

The task of localizing single and multiple concurrent speakers in a reverberant environment
with background noise poses several problems. One of the major problems is the severe …
