A Probabilistic Framework for Multiple Speaker Localization

This paper presents a novel probabilistic framework for localizing multiple speakers with a microphone array. In this framework, the generalized cross correlation function (GCC) of each microphone pair is interpreted as a probability distribution of the ti ...

Spatial Acoustic Signal Processing

Mihailo Kolundzija

A sound field on a line or in a plane has an effectively limited spatial bandwidth determined by the temporal frequency. Similar can be said for sound fields from far-field sources when analyzed on circular and spherical apertures. Namely, for a given freq ...

Practical 3 dimensional sound reproduction using Wave Field Synthesis, theory and perceptual validation

Hervé Lissek, Xavier Falourd, Lukas Rohr

Sound ﬁeld reproduction using Wave Field Synthesis has been so far limited to the positioning of virtual sources and listeners in the horizontal plane only although the underlying formulation (Kirchhoﬀ-Helmholtz) describes the reproduction of 3 dimensional ...

Baffled Circular Loudspeaker Array With Broadband High Directivity

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Super-directional loudspeaker arrays can be used to achieve high directivity in a limited low-frequency range. As opposed to microphone arrays, the distance between the loudspeakers has to be relatively large, resulting in aliasing starting at relatively l ...

Spatial echogram analysis of a small auditorium with observations on the dispersion of early reflections.

Hervé Lissek, Xavier Falourd, Lukas Rohr

Classical room acoustics are based on the interpretation of different sound attributes such as reverberation time, clarity and spatial decay. Based on echograms calculated from a microphone array, the dispersion of early reflections is measured and the ref ...

Visual Speaker Localization Aided by Acoustic Models

The following paper presents a novel audio-visual approach for unsupervised speaker locationing. Using recordings from a single, low-resolution room overview camera and a single far-field microphone, a state-of-the art audio-only speaker localization syste ...

Method And Device For Removing Echo In A Multi-Channel Audio Signal

Christof Faller

Acoustic echo control and noise suppression is an important part of any "handsfree" telecommunication system, such as telephony or audio or video conferencing systems. Bandwidth and computational complexity constraints have prevented that stereo or multi-c ...

Spatio-temporal analysis of spontaneous speech with microphone arrays

Guillaume Lathoud

Accurate detection, localization and tracking of multiple moving speakers permits a wide spectrum of applications. Techniques are required that are versatile, robust to environmental variations, and not constraining for non-technical end-users. Based on di ...
