  1. 1. Multichannel Audio Signal Processing : Room Correction and Sound Perception

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Adrian Bahne; Anders Ahlén; Lars-Johan Brännmark; Mathias Johansson; Peter Händel; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio signal processing; multichannel sound reproduction; equalizers; human sound perception; room correction; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Abstract : This thesis concerns and combines multichannel sound reproduction, digital room correction, audio signal processing, and human sound perception. It investigates perceived sound quality and new methods to improve timbral and spatial fidelity of loudspeaker-based multichannel sound reproduction in reverberant environments. READ MORE

  3. 3. Group-Sparse Regression : With Applications in Spectral Analysis and Audio Signal Processing

    University dissertation from Mathematical Statistics, Centre for Mathematical Sciences, Lund University

    Author : Ted Kronvall; [2017-09-22]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sparse regression; group-sparsity; statistical modeling; regularization; hyperparameter-selection; spectral analysis; audio signal processing; classification; localization; multi-pitch estimation; chroma; convex optimization; ADMM; cyclic coordinate descent; proximal gradient;

    Abstract : This doctorate thesis focuses on sparse regression, a statistical modeling tool for selecting valuable predictors in underdetermined linear models. By imposing different constraints on the structure of the variable vector in the regression problem, one obtains estimates which have sparse supports, i.e. READ MORE

  4. 4. Digital signal processing methods and algorithms for audio conferencing systems

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Fredric Lindström; ; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio conferencing systems;

    Abstract : Today, we are interconnected almost all over the planet. Large multinational companies operate worldwide, but also an increasing number of small and medium sized companies do business overseas. As people travel to meet and do businesses, the already exposed earth is subject to even more strain. READ MORE

  5. 5. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Audio; Audio Pre-compensators; Causal Filters; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. READ MORE
