A bayesian direction-of-arrival model for an undetermined number of sources using a two-microphone array

Escolano Carrasco, José; Xiang, Ning; Pérez-Lorenzo, José M.; Cobos Serrano, Máximo; López Monfort, José Javier (Acoustical Society of America, 2014-02)

Sound source localization using a two-microphone array is an active area of research, with considerable potential for use with video conferencing, mobile devices, and robotics. Based on the observed time-differences of ...
A modified SRP-PHAT functional for robust real-time sound source localization with scalable spatial sampling

Cobos Serrano, Máximo; Martí Guerola, Amparo; López Monfort, José Javier (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)

The Steered Response Power – Phase Transform (SRP-PHAT) algorithm has been shown to be one of the most robust sound source localization approaches operating in noisy and reverberant environments. However, its practical ...
Material sound source localization through headphones

Dunai, Larisa; Peris Fajarnes, Guillermo; Lengua, Ismael; Tortajada Montañana, Ignacio (MAIK NAUKA/INTERPERIODICA/SPRINGER, 2012)

[EN] In the present paper a study of sound localization is carried out, considering two different sounds emitted from different hit materials (wood and bongo) as well as a Delta sound. The motivation of this research is ...
Multichannel audio processing for speaker localization, separation and enhancement

Martí Guerola, Amparo (Universitat Politècnica de València, 2013-10-29)

This thesis is related to the field of acoustic signal processing and its applications to emerging communication environments. Acoustic signal processing is a very wide research area covering the design of signal processing ...
On the performance of multi-GPU-based expert systems for acoustic localization involving massive microphone array

Belloch Rodríguez, José Antonio; Gonzalez, Alberto; Vidal Maciá, Antonio Manuel; Cobos Serrano, Máximo (Elsevier, 2015-08-01)

Sound source localization is an important topic in expert systems involving microphone arrays, such as automatic camera steering systems, human-machine interaction, video gaming or audio surveillance. The Steered Response ...
Real-Time Sound Source Localization in Videoconferencing Environments

Martí Guerola, Amparo (Universitat Politècnica de València, 2013-02-19)

[ES] Los mecanismos de Localización de Fuentes de Sonido (SSL) han sido ampliamente estudiados. Muchas aplicaciones como sistemas de teleconferencia o realzado de voz necesitan la localización de una o más fuentes ...
Speaker Localization and Detection in Videoconferencing Environments Using a Modified SRP-PHAT Algorithm

Martí Guerola, Amparo; Cobos Serrano, Máximo; Aguilera Martí, Emanuel; López Monfort, José Javier (Instituto de Telecomunicaciones y Aplicaciones Multimedia (ITEAM)", 2011)

[EN] The Steered Response Power - Phase Transform (SRP-PHAT) algorithm has been shown to be one of the most robust sound source localization approaches operating in noisy and reverberant environments. However, its practical ...
