Speaker: Regis Rossi Alves Faria (Music Dept., FFCLRP/USP)
Date and time: Thursday, October 10, 2013 - 13:00
Place: Room B-3, IME/USP
Abstract: In this talk we will present the main references in the engineering of systems for spatial audio. We will present existing architectures, projects for development of auralization technologies and multichannel audio, with a view of our research on auralization at USP. We will also show popular commercial systems and interesting applications, ending with a discussion on the next steps in this field.

Abstract: Csound is a computer music language developed at MIT nearly 30 years ago that is still widely used. Their latest versions now support livecoding, and Csound was also selected as the audio system of the project One Laptop Per Child (OLPC). Besides its basic C API, the language can be used with Python, Java, Lisp, Tcl, C + +, Haskell and many other languages. At this talk we will discuss about how Csound can be used on devices with Android. First we will talk about solutions for non-developers that only want a basic interface, and then we will see methods for programming using Java and Csound in applications for Android.

Abstract:
In this talk we will present a paper by Joshua J. Bloch and Roger B. Dannenberg entitled "Real-Time Computer Accompaniment of Keyboard Performances" (ICMC 1985). In this paper a set of algorithms is developed to deal with real-time accompaniment of polyphonic performances.
We are in a scenario in which the computer listens to a musician's performance, compares the events of the input with the events of a score and, with a high correlation between them, infers a tempo and plays the appropriate accompaniment.
To handle with polyphonic instruments, the authors considered three design decisions: define the meaning of best association between performance and score, decide with confidence which point of the score the musician is and group disordered notes into compounds events.

Date and time: Thursday, September 19, 2013 - 13:00
Place: Room B-6, IME/USP
Abstract: In this talk we will revisit some of the main references in the conception and implementation of spatial audio systems. In a chronological journey we will approach the ideas, inventions and audio engineering solutions behind the most interesting commercial system implementations to date. We will conclude with a vision of our own research in auralization at USP and open issues for the future.

Abstract: Audio streaming is often pictured as a networking application that is not concerned with packet loss or data integrity, but is otherwise very latency-sensitive. However, some usage scenarios may be identified, such as remote recording, that shift concerns towards more conservative views regarding stream integrity. Although many streaming applications today use the UDP protocol, there are some alternative transport layer protocols that are worth investigating, especially in applications other than Voice-over-IP (VoIP) or live distributed performance. In this seminar we will compare audio streaming in local-area computer networks over four different transport protocols on the TCP/IP stack: TCP, UDP, STCP and DCCP. Each of these protocols and their features will be discussed, first from a theoretical point-of-view, and then through experimental results.
