Anotation:
The course deals with topics from electro acoustics, sound reinforcement, related signal processing in conjunction with psychoacoustic aspects. It prepares experts for studio practice, design of sound reinforcement and specialized field in signal processing.
Study targets:
Students acquire knowledge on analysis and synthesis of electro acoustic systems and acoustic field including sound reinforcement. In the signal processing part they learn the influence of psychoacoustic phenomena in audio signal analysis and synthesis.
