Motivation

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.  

The course is taught in English


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.


 

Final exam modalities

 

The exam consists of a discussion of an assigned project (home-work or “tesina”) (max 24pt) and some theoretical questions (max 6pt). 

 

The home-work is assigned to the student at the course end (during the year, when required), and typically the student can choose the project from a list of possible topics.

 

The project can also be done by a group of maximum 3 students. In this case the task of each individual student must be well specified.


The final discussion of the project is done at the teacher's office (or remotely with g-meet/zoom)  by appointment at any period of the year. For the final exam the student must:

1) present a report (in the form of a short scientific paper) on the project carried out;

2) give a short presentation (using slides, demos, etc.) in which the results and the acquired skills are highlighted.
