Audio systems

Course Description

The course will offer knowledge on the following topics: Audio data storage technologies. Advantages and disadvantages of analogue and digital audio systems. Perceptual encoding of audio signals and audio data reduction. Digital interfaces for connecting audio systems. Multichannel audio systems. Binaural audio systems with and without head position tracking. Multi microphone systems for sound field recording. Microphone arrays. Analysing audio signals based on extraction of audio signal features. Audio forensics.

Learning Outcomes

  1. classify typical studio and control room audio system components
  2. analyze media and formats for storage of audio signals
  3. demonstrate perceptual encoding of audio signals
  4. use different digital interfaces for connecting audio systems
  5. analyze input and output audio system components
  6. analyze audio signals using chosen signal features
  7. apply norms for measuring audio systems

Forms of Teaching

Lectures

The theory of audio systems is explained. These phenomena are also explained through demonstrations, where applicable.

Seminars and workshops

Independent processing of a selected topic from the areas covered in the course.

Laboratory

Through exercises in small groups, students will analyze the elements of the audio chain and the functionality of advanced audio systems.
