  2. 11. On the Enhancement of Audio and Video in Mobile Equipment

    Author : Andreas Rossholm; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Audio enhancement; video enhancement; active noise cancellation; video coding; mobile equipment;

    Abstract : Use of mobile equipment has increased exponentially over the last decade. As use becomes more widespread so too does the demand for new functionalities. The limited memory and computational power of many mobile devices has proven to be a challenge resulting in many innovative solutions and a number of new standards. READ MORE

  4. 12. An investigation of qualitative research methodology for perceptual audio evaluation

    Author : Dan Nyberg; Natanya Ford; Luleå tekniska universitet; []
    Keywords : HUMANIORA; HUMANITIES; 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

  5. 13. Parameter and State Estimation with Information-rich Signals

    Author : Magnus Evestedt; Alexander Medvedev; Fredrik Gustafsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; information-rich signals; audio; video; acoustic echo cancellation; steel production; LD-converter; Kalman filter; covariance windup; recursive parameter estimation; Automatic control; Reglerteknik;

    Abstract : The complexity of industrial systems and the mathematical models to describe them increases. In many cases, point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. READ MORE

  6. 14. Perceptual and Squared Error Aspects in Speech and Audio Coding

    Author : Harald Pobloth; Bastiaan Kleijn; Gernot Kubin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; speech coding; audio coding; auditory models; perceptual distortion measures; squared error; Signalbehandling; Signal processing; Signalbehandling;

    Abstract : In the process of quantization, speech and audio signals are changed. This thesis contains four papers concerned with comparing and minimizing different measures to quantify the changes introduced. Before quantization the signal can be transformed to another domain. Transforms related to the discrete Fourier transform allow for e. READ MORE

  7. 15. Participant Reference in Three Balochi Dialects : Male and Female Narrations of Folktales and Biographical Tales

    Author : Maryam Nourzaei; Carina Jahani; Stephen H. Levinsohn; Henrik Liljegren; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Balochi; Coastal Balochi; Koroshi Balochi; Sistani Balochi; folktales; biographical tales; participant reference; default and marked encoding; orality; Iranska språk; Iranian Languages;

    Abstract : The aim of the present study is to investigate how men and women in three Iranian Balochi dialects, Coastal Balochi, Koroshi Balochi and Sistani Balochi, refer to 3rd person participants in oral narratives of two genres: folktales and biographical tales. The stories that are analysed were recorded during several field trips to Iran and the approach used is that of Levinsohn (1994, 2015). READ MORE
