The introduction of modern technologies, starting with recording, transduction and amplification techniques, to the most recent digital synthesis and encoding techniques, and internet, has had an extraordinary impact on the ways in which vocal and musical messages are created, transmitted and enjoyed.

Simultaneously, computer simulation techniques of acoustic phenomena, and increasing knowledge of the characteristics of the human auditory system, contribute to a better understanding of the fundamental factors that determine the perception of sounds and the acoustic signal in general.

The main objective of the course DASP, is to present the basic elements for studying the perceptual patterns of the listener, the listening environment; circuits and algorithms for capturing, processing, synthesizing, and reproducing high-quality audio signals.

Required prerequisites

There are no particular prerequisites other than the basic topics of mathematics, calculus, and algebra, typical of the two years of engineering and other scientific faculties.

Course objectives and skills acquired by the student

Study of specific methods for capturing, processing, synthesis, of multichannel audio signals in all possible application scenarios.
