The students will acquire the following competences: - Know the audio signal in its analog and digital forms, and the processing pipeline for an effective and high performance conversion between both (A / D and D / A chain). - Analyze and design usual devices and equipments in the professional audio chain, covering both the processing and distribution of the audio signal: processors in time, frequency processors, dynamics processors and mixing consoles. - Know systems and interfaces for digital interconnection, and audio coding techniques that allow efficient and robust storage and transmission. - Design and deploy some fundamental applications that involve processing and distribution of the audio signal in professional environments: recording process and mixing of a sound program, stereo and multichannel sounding of audio programs, room equalization for sound reinforcement , etc..

CB1: Students have demonstrated possession and understanding of knowledge in an area of study that builds on the foundation of general secondary education, and is usually at a level that, while relying on advanced textbooks, also includes some aspects that involve knowledge from the cutting edge of their field of study. CB2: Students are able to apply their knowledge to their work or vocation in a professional manner and possess the competences usually demonstrated through the development and defence of arguments and problem solving within their field of study. ETEGISA1: Ability to construct, develop and manage telecommunication networks, services, processes and applications, such as systems for capture, analog and digital processing, codification, transport, representation, processing, storage, reproduction, audiovisual services presentation and management and multimedia information. ETEGISA2: Ability to analyze, specify, implement and maintain television, audio and video systems, equipment, headends and installations, in fixed as well as mobile environments. RA1: To acquire the knowledge and understanding of the general basic fundamentals of engineering, as well as, in particular, of multimedia communications networks and services, audio and video signal processing, room acoustic control, distributed multimedia systems and interactive multimedia applications specific to Sound and Image Engineering within the telecommunications family. RA2: Be able to carry out an analysis process to solve problems of recording, conditioning, compression of audio and video signals, acoustics of enclosures, networks, services, systems and applications in audiovisual systems. Graduates will be able to identify the problem, recognize the specifications, establish different resolution methods, select the most appropriate one and implement it correctly. They will be able to use various methods and recognize the importance of social constraints, human health, safety, the environment, as well as commercial constraints. RA3: To be competent to carry out engineering designs in their field within Sound and Image Engineering, working as a team. Design encompasses devices, processes, methods and objects, and specifications that are broader than strictly technical, including social awareness, health and safety, environmental and commercial considerations. RA4: To be able to carry out research and carry out innovative contributions in the field of Sound and Image Engineering, including bibliographic search and comprehension as well as the design and development of experiments that solve the challenges of knowledge in the field of audiovisual systems, in terms of the capture, processing, adaptation, diffusion and consumption of multimedia contents, as well as associated networks, services and applications, which justifies the scientific interest of this Degree. RA5: Be competent to apply the knowledge acquired to solve problems and design audiovisual networks and services, to configure their devices, as well as to deploy adaptive, personal audiovisual applications and services on them, bringing network intelligence to the value for the user, maximising the potential of multimedia networks and services in the different social and economic spheres, knowing the environmental, commercial and industrial implications of the practice of engineering in accordance with professional ethics.

1.- Introduction to audio signal 2.- Digital audio fundamentals. A/D and D/A conversion.

Three teaching activities are proposed: theoretical classes, exercises, and lab exercises. THEORETICAL CLASSES The theoretical class will be given in the blackboard, with slides or by any other means to illustrate the concepts of the lectures. In these classes the explanation will be completed with examples. In these sessions the student will acquire the basic concepts of the course. It is important to highlight that these classes will require the initiative and the personal and group involvement of the students (there will be concepts and particular cases that the students themselves should develop). EXERCISES Through these sessions, the student will apply the studied theoretical concepts to concrete problems and scenarios of audio systems. Sometimes, the teacher will directly solve the problems, whereas in others, the students will first solve the problem and to later discuss their answers. LABORATORY EXERCISES Basic concepts learnt during the course will be applied in the laboratory. The lab exercises will be carried out using the lab equipment (acoustic instrumentation and audio equipment) and simulation and design software. There will be guided exercises and an audio coding design exercise.
