Seminar by prof. Andrea Valle “Sound Synthesis and Algorithmic Composition: the SuperCollider development environment” (Dec 10, 2014, 14:30, room 2T), as part of the “Processing of Digital Audio” course.
Detailed information (Italian only):
Il seminario intende fornire una panoramica introduttiva alla sintesi del segnale audio in tempo reale e alla composizione/improvvisazione con il calcolatore per applicazioni musicali. A tal fine verrà presentato l’ambiente open source SuperCollider.
Ricercatore dell’Università di Torino presso il CIRMA (Centro Interdipartimentale di Ricerca sulla Multimedialità e l’Audiovisivo) il prof. Andrea Valle insegna “Audiovisione e Multimedialità” per i corsi di laurea del DAMS (Department of Fine Arts, Music and Performing Arts).
Valle è autore di alcuni libri tra cui ricordiamo:
“Audio e Multimedia” (Apogeo) libro di testo del corso di Elaborazione dell’Audio Digitale al Politecnico di Torino

The new PhD course “Multimedia Communications: Technological Advances and Social Implications” is scheduled to begin on November 20, 2014. All PhD students can participate (including “XXX ciclo” that started Nov 1, 2014). Three members of our research group (Enrico Masala, Antonio Servetti, Juan Carlos De Martin) will cover all the course topics, as better specified in the course webpage.
The thesis section of the website has been updated including 5 new theses in collaboration with companies (SYSMAN and C-System). The rules (“bando”) are available at this link. The new deadline for the application is October 20, 2014 (the linked document still reports the old deadline, which must not be considered).
The Internet Media Group is delighted to announce Simone Basso‘s presentation of his research activities developed during the course of his PhD studies. The presentation, about Neubot and network neutrality issues, will be held at the Nexa Center for Internet and Society on Wednesday Jul 9, 2014, 6pm-8pm, Via Boggio 65/a, Torino (first floor). More details on the Nexa center website.
Prof. Genoveva Vargas Solar, prof. Guadalupe Solar Quiroz, prof. José Luis Zechinelli Martini and Dr. Javier Espinosa from Universidad de las Américas Puebla (UDLAP) and LAFMIA will visit our group for one month starting May 26, 2014. Prof. David Baez-Lopez will also join them for one week starting May 26, 2014. All visits are part of the activities of the FP7 S2EuNet project. We are looking forward to welcoming and collaborating with them.
The seminar will be held on Monday 12, 2014, at 14:30, in the Department of Control and Computer Engineering (DAUIN), meeting room 5th floor.
This talk revisits the question of scalable coding. Often the same content is served at different data rates and quality levels to various users. The simplest approach is to store and transmit independent copies of the signal at different quality levels, which is obviously wasteful in resources. The alternative approach of scalable coding imposes a rigid hierarchical structure, wherein the base layer information is subsumed in the higher layer information, and is widely recognized to incur a performance penalty compared to independent encoding. Instead of assuming such a rigid structure, we propose sharing only an appropriate subset (carefully selected) of base layer information with the enhancement layer. Concepts from classical Information theory (common information as defined by Wyner and by Gacs-Korner) provide a foundation and imply that this flexibility is indeed key to achieve efficiency in storing and transmitting signals at different quality levels, by optimally sharing information that is “common” to them. As an example, we then employ this framework to audio coding with the MPEG Scalable AAC and describe an optimization scheme to jointly select parameters of all the layers. Results for this coder provide practical evidence for the utility of such a flexible framework.
Kenneth Rose joined the Department of Electrical and Computer Engineering, University of California, Santa Barbara, in 1991 after receiving his Ph.D. from Caltech. His research activities are in the areas of information theory, signal compression, source-channel coding, video/audio coding and processing, pattern recognition, and nonconvex optimization. He is particularly interested in application of information and estimation theoretic approaches to fundamental problems in signal processing, as well as in the underlying relations between information theory and statistical physics. Recent research contributions of his group include methods for end-to-end distortion estimation in video transmission and streaming over lossy packet networks, optimal prediction in scalable video and audio coding, distributed source coding and sensor networks, as well as information theoretic approaches to optimization with applications in pattern recognition, signal compression and content-based search and retrieval from high-dimensional databases. His optimization algorithms have been adopted by others in numerous disciplines beside electrical engineering and computer science, including physics, chemistry, biology, medicine, materials, astronomy, geology, psychology, linguistics, ecology, and economics. Among various professional activities, Rose has served as an Area Editor for the IEEE Transactions on Communications, as a member of the IEEE Signal Processing Society’s Image and Multidimensional Signal Processing Technical Committee, and the Multimedia Signal Processing Technical Committee, and as co-Chair of the technical program committee of the 2001 IEEE Workshop on Multimedia Signal Processing, Cannes, France. He is a fellow of the IEEE and was the recipient or co-recipient of several journal and conference paper awards.
In the context of the activities of the FP7 S2EuNet project, Antonio and Enrico will visit UDLAP, Puebla, Mexico from Feb 19 to Mar 2, 2014, together with professors from other institutions participating in the same project. All of them will also participate in the S2EuNet Workshop on Feb 25, 2014, and in the CONIELECOMP conference organized by UDLAP in the following days.
