Audio Technology

Audio Technology has both technical and artistic approaches and addressing the various elements of audio production for various media including live context, and how the audible result is affected.

Audio Technology has evolved from traditional academic disciplines and artistic needs related to the recording, processing and reproduction of sound. Audio Technology designed to make technology and content to interact within the sound field to allow for different listening experiences. It is an important part of sound engineering methods for evaluating sound quality. Over the years, a development occurred from measurements of physical properties to include the listener's assessment of perceived quality characteristics. In addition, the relationship between physical properties, sound technical methods and perceived sound quality an important part.

The research focuses on assessing quality audio and sound recording technology. This includes development of evaluation methods and the utilization of the results of these evaluations. In addition to recording techniques and artistic övverväganden occurring elements such as music, acoustics, electronics and psychology. In research, this is visible through an assessment of the perceived performance of eg microphone configurations and algorithms for audio processing / encoding.

Research is conducted in cooperation with several universities and commercial companies. Business-related research concerns such as quality testing of applications, or intended to be commercially available, and the previous examples include mp3PRO and MPEG-4 aacPlus.

Research The profile also includes evaluation of other properties of sound - such as developing methods for evaluating the perceived characteristics of music and changes in musical parameters that may be useful in applications where music is an important part, eg in computer games.

Honorary doctor and sound engineer Bruce Swedien is dead

The American sound engineer Bruce Swedien is dead. He worked with producer Quincy Jones on several of Michael Jackson's albums. He also worked with jazz legends such as Count Basie, Duke Ellington and Dinah Washington. He was awarded an honorary doctorate at Luleå University of Technology in 2001.

Sound art in interaction with nature

Musicians have always been inspired by nature and living environment in their creative process. Few have, however, created music in direct interaction with the surroundings, but that was exactly what the researchers in the sound art project Invisible Sounds: Piteå Port did when visiting Pite Harbor in search of sounds that cannot be perceived with the bare ear.

Even sound levels may require legislation

Many have certainly noticed that the volume may be commuting on the radio or felt compelled to adjust the volume when the sound level suddenly changes during television broadcasts. Differences in perceived noise levels have long been a problem in both radio and TV, but new research at Luleå University of Technology can help to minimize the problem.
