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 ...
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 ...
Procesado de señal en array para el análisis de ruido exterior en vehículos ferroviarios

Guarch Pérez, Elena (Universitat Politècnica de València, 2015-06-01)

[EN] Design an own tool that generates a sound map of a railway vehicle to detect the main external noise source
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 ...
Two-microphone multi-speaker localization based on a Laplacian Mixture Model

Cobos Serrano, Máximo; López Monfort, José Javier; Martinez Perez, David (Elsevier, 2011-01)

A method for multiple speaker localization using a two-microphone array is presented. Based on the disjointness property of speech signals in the time-frequency (TF) domain, the proposed approach models the distribution ...
Visualization of measured sound source directivities

Asensi Peiró, Marta (Universitat Politècnica de València, 2020-03-24)

[ES] Tanto en las fuentes de sonido como en los receptores podemos cuantificar el compor-tamiento dependiente de la dirección y frecuencia por medio de los patrones de directi-vidad. Sabemos que estos patrones tienen una ...
