  1. 1. An investigation of qualitative research methodology for perceptual audio evaluation

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Dan Nyberg; Luleå tekniska universitet.; [2012]
    Keywords : HUMANIORA; HUMANITIES; Qualitative methods; Audio; Sound; Audio technology; Subjective assessment; Naive Listeners; Information technology - Other information technology; Ljudteknik; Kvalitativa metoder; Ljudkvalité; Lyssningstest; Informationsteknik - Övrig informationsteknik; Ljudteknik; Audio Technology;

    Abstract : This thesis investigates whether a qualitative research method, using phenomenological interviews and analysis, can be successfully applied to perceptual audio research, a field heretofore that has mainly used quantitative methods. The method is investigated by studying the types of information elicited by the method and the information’s usefulness and relevance to the conducted study. READ MORE

  2. 2. Towards flexible audio coding

    University dissertation from Stockholm : Signaler, sensorer och system

    Author : Renat Vafin; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Audio coding; multistage coding; waveform coding; parametric coding; sinusoidal coding; Elektronik; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Abstract : thesis is about audio coding and improving flexibility thereof. Audio coding is used to reduce the bit rate needed to represent audio signals in digital format. When the available bit rate is low, parametric coding methods that use models to describe perceptually-important features of audio signals have shown their efficiency. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Simon Widmark; Uppsala universitet.; [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

  4. 4. Enabling audio-haptics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kirsten Rassmus-Gröhn; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synskador och blindhet; Haptiska gränssnitt - Virtual Reality;

    Abstract : This thesis deals with possible solutions to facilitate orientation, navigation and overview of non-visual interfaces and virtual environments with the help of sound in combination with force-feedback haptics. Applications with haptic force-feedback, sp... READ MORE

  5. 5. User Centered Design of Non-Visual Audio-Haptics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kirsten Rassmus-Gröhn; Lund University.; Lunds universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Haptic; audio; non-visual; user-centered design; school; drawing; children;

    Abstract : The following article reports result from an extensive study with 25 blind users from Italy and Sweden performed during the summer 2001. The tasks reported here test recognition of geometrical objects, recognition of VRML objects, mathematical surfaces and navigation in a traffic environment. READ MORE
