Audiosystems

Course Description

Audio signal transfer in audio communications begins and ends with an audio system, regardless of the transfer mode and type. Because of its importance it is necessary to understand: Studio and control room audio technology. Digital audio transfer systems. Recording media for audio signals. Home audio components. Audio quality based on perceptual measuring techniques. Audio signal processing. Perceptual coding of high-quality digital audio systems. Digital audio system architecture. Input-output audio system components. Audio signal analysis. Audio signal synthesis. Digital communication audio systems. Interfaces for connecting audio system components. Processing and editing of audio signals in multichannel systems. Measurements on audio systems

General Competencies

The subject gives the necessary qualifications for understanding audio signal transfer in audio communications through different audio systems.
