Content and learning outcomes
Course contents *
Two- and three-dimensional sound reproduction, surround formats. A/D and D/A conversion for audio in detail. Studio signal processing. Data reduction methods. Integrated circuits for audio. Hard disks and audio. Optical disks in audio. Sound quality assessment. Software architectures for audio. Audio in broadcasting. The course assignment involves writing an in-depth article on a self-selected sub-topic in audio. Several guest lecturers contribute with their expertise. For a detailed description, please see the home page of this course.
Intended learning outcomes *
The participants shall upon completion of this course
- be able to specify at a block diagram level the functions/components that must or may be included in audio systems for various applications; with regard for technical constraints such as channel count, converter types, data reduction methods, power requirements and storage
- be able to assess audio systems with regard to sound quality and suitability in given applications
- be acquainted with how real-time audio data are usually managed in audio software and in operating systems
- have obtained basic experience with using a mixing desk and its major peripherals such as dynamics processor, reverb unit and equaliser
- be able to understand the first few pages of data sheets for audio integrated circuits
- be able to participate in the planning, deployment and maintenance of new and existing systems
- have a broad perspective on how transforms, signal theory, discrete mathematics, information theory, electronics and physics all come together in audio applications

Literature and preparations
Specific prerequisites *
Single course students: 90 university credits including 45 university credits in Mathematics or Information Technology. English B, or equivalent.
Recommended prerequisites
The prerequisite knowledge varies with the background of the participant. This course is elective for Media 3-4, E4 and D4. In the Media Technology programme, the course is taken as part of a major (with thesis) or a minor (without thesis) in Sound.
For Media 3-4: DT1175 Sound and DT1130 Spectral transforms for Media.
All others: some fundamentals of electrical engineering with signal theory and signal processing, and some acoustics. If in doubt, please e-mail the examiner with your course record.
Media Technology: the theory for perception of sound and for what is communicated to the listener. Electrical Engineering: the theory of audio signals and digital technology in audio systems. Computer Science: the theory for sound-based man-machine interaction, and systems programming.
