Model-based Sparse Component Analysis for Reverberant Speech Localization

Hervé Bourlard, Volkan Cevher, Afsaneh Asaei, Mohammadjavad Taghizadeh

In this paper, the problem of multiple speaker localization via speech separation based on model-based sparse recovery is studies. We compare and contrast computational sparse optimization methods incorporating harmonicity and block structures as well as a ...

Perception and Reproduction of Auditory Spatial Impression

Andreas Walther

As audio reproduction systems evolve to incorporate many loudspeakers, the potential to evoke faithful auditory spatial impressions increases. Psychoacoustic principles of auditory spatial perception, and methods for production and reproduction of acoustic ...

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 ...

A practical formulation of 3 dimensional sound reproduction using Wave Field Synthesis

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 dimension ...

Reproducing Sound Fields Using MIMO Acoustic Channel Inversion

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Sound fields are essentially band-limited phenomena, both temporally and spatially. This implies that a spatially sampled sound field respecting the Nyquist criterion is effectively equivalent to its continuous original. We describe Sound Field Reconstruct ...

Design of a Compact Cylindrical Loudspeaker Array for Spatial Sound Reproduction

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Building acoustic beamformers is a problem whose solution is hindered by the wide-band nature of audible sound. In order to achieve a consistent directional response over a wide range of frequencies, a conventional acoustic beamformer needs a high number o ...

2011

The generation of subjectively diffuse sound fields is an essential part of creating pleasing synthetic sound fields using loudspeaker playback. A number of studies have been published presenting subjective evaluations of the diffuse sound field reproducti ...

2011

Binaural room impulse responses (BRIRs) characterize the transfer of sound from a source in a room to the left and right ear entrances of a listener. Applying BRIRs to sound source signals enables headphone listening with the perception of a three dimensio ...

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 ...
