Abstract:

L’audiodescripció (AD) ja no és considerada un servei exclusiu d’accessibilitat, dedicat a una petita fracció d’individus, sinó que s’entén com un servei inclusiu, dirigit no només a les persones amb discapacitats sensorials, sinó també a altres audiències, com els ancians o els nens. És probable que la demanda d’aquest servei creixi en un futur pròxim. Encara que en el mercat s’observa un interès en augmentar cada cop més la oferta de productes audiovisuals accessibles, no s’hauria de deixar de banda la qualitat de l’experiència de l’usuari.

Abstract:

The development and improvement of 3-D immersive audio is gaining momentum through the growing interest in virtual reality. Possible applications reach from recreating real world environments to immersive concerts and performances to exploiting big data acoustically. To improve the immersive experience several measures can be taken. The recording of the sound field, the spatialization and the development of the loudspeaker arrays are some of the greatest challenges. In this thesis, these challenges for improving immersive audio will be explored. First, there will be a short introduction about

Abstract:

In immersive audio environments with distributed microphones, Independent Component Analysis (ICA) can be applied to uncover signals from a mixture of other signals and noise, such as in a cocktail party recording. ICA algorithms have been developed for instantaneous source mixtures and convolutional source mixtures. While ICA for instantaneous mixtures works when no delays exist between the signals in each mixture, distributed microphone recordings typically result various delays of the signals over the recorded channels. The convolutive ICA algorithm should account for delays; however, it re

Abstract:

The Generalized Sidelobe Canceller is an adaptive algorithm for optimally estimating the parameters for beamforming, the signal processing technique of combining data from an array of sensors to improve SNR at a point in space. This work focuses on the algorithm’s application to widely-separated microphone arrays with irregular distributions used for human voice capture. Methods are presented for improving the performance of the algorithm’s blocking matrix, a stage that creates a noise reference for elimination, by proposing a stochastic model for amplitude correction and enhanced use of cross

Genom att ta in information med hjälp av olika medel som exempelvis ljudeffekter och animationer kan spelaren göra snabba och reaktiva beslut.

Abstract:

Virtual Reality (VR) can potentially transport the user to another world. Outside of VR, musical soundtrack is usually placed outside of the scene, referred to as non-diegetic sound. In VR, this could potentially break immersion. Other ways to implement music have to be tested. A test was created consisting of three scenes with a wide selection of “listening modes”, or musical configurations. The listening modes ranged from non-diegetic stereo music via headphones to diegetic, played from speakers inside the VR spaces. 10 respondents played through the scenes in VR, experiencing every listenin
