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.

General Competencies

Good understanding of the problems and solutions of sound recordings and procesing, with applications to computers. Theoretical and practical knowledge about methods and techniques in measuring of sound, with applications to computers. Basic knowledge about methods and techniques in sound processing.

Forms of Teaching


Lectures are held in two cycles, 3 hours per week. After each cycle assessment is carried out.


Continuous assessment is carried out through mid-term exams and final exams. Assessment on the examinations are carried out according to schedule.

Laboratory Work

Three laboratory exercises are provided, they are graded, and take place under the supervision of an assistant.


Demonstration of some phenomena that are topics at a lecture

Experimental Exercises

More complex demonstration of some phenomena that are topics at a lecture


Consultations take place according to agreement with the teacher


Individual work for selected topic from the area of the whole course
