Audio and Computers

Course Description

The application of computers has become inevitable when sound recording and processing is concerned. The following thematic units are elaborated in detail: A/D conversion. D/A conversion. Ways of exchanging audio content and the formats used in the process. Media and formats used for storage of audio content. Characteristics of sound cards. Recording, editing and processing of audio using a computer. Computer control of musical instruments. Computer-aided sound analysis. Computer-aided sound synthesis. Computer-controlled sound reinforcement and PA systems. Computer-controlled radio-diffusion systems. Multimedia home systems. Audio content archives. Computer-aided and controlled electroacoustical measurements.
