Rules for evaluation and completion of the course
It is obligatory to work through all laboratory exercises in regular or alternative terms to complete the course. Other forms of checked instruction are specified by a regulation issued by the guarantor of the course and updated for every academic year.
Aims
After course completion, students are to:
- describe the structure of the mixing console, explain its operation and use it for recording or sound reinforcement,
- explain the principles of measurement of level and other parameters of analog and digital audio signals,
- describe the structure and operation principle of the basic types of audio effects, describe the type of transformation which occurs in them, and use them for audio processing,
- explain the principle of digital audio signal processing and transmission,
- explain the principle and structure of digital audio signal hard disc recording (HDR),
- describe the structure of various types of audio interfaces and structure of digital audio workstations (DAW),
- describe the structure of the MIDI protocol, enumerate the messages it uses, and use them for controlling studio equipment,
- describe the types of synchronization signal, choose the proper type of synchronization for a given system,
- describe the structure of the DMX512 protocol and use it for controlling light and stage equipment.
