Place: Room B-3, IME/USP
Abstract:
In this talk I will present three applications of coupled audio/sensor signal processing I worked with in the first two years of my PhD, which are summarized below:
- Sennheiser microphone prototype (Tahoe): I will present what I did during my internship at Sennheiser Palo Alto on the Tahoe microphone. The Tahoe microphone functions as a wireless microphone and doubles as a midi controller, integrating several different sensors on the body for the musician to control effect gear or software on a computer in the same device, allowing more expressiveness when performing live.
- BeachTracker: A tracking system I developed for tracking beach volleyball players and the ball from videos taken with a static camera from the audience. The tracking method uses a particle filter approach and was a project together with the Technical University of Munich and the German Beach Volleyball Association.
- Improvement of spatial audio in hearing-aids: I will present the basic idea about my project with Phonak explaining the advantages and disadvantages of hearing-aid types, and the goal of combining the advantages of the different hearing-aid types in order to improve the spatial perception of the user.

Abstract:
In this talk will be presented a proposal of a tool to control audiovisual resources in artistic expressions using open projects like the Open Lighting Architecture (OLA), which provides communication by the standard protocol of lighting equipment, DMX512, and the visual programming language Pure Data, widely used for sound processing. The goal is to reduce the equipment cost and make more accessible the technical knowledge needed to manipulate them, also providing new possibilities of interaction between visual and sound elements.

Abstract:
In this talk we will introduce elementary concepts referring to random audio signal processing. This expression should not be confused with any reference to a sound/timber property or a characterization of a signal's contents, but as a reference to signal models and hypotheses related to signal description. Deterministic and stochastic approaches for classical problems such as prediction and interpolation will be compared, and solutions for stochastic filtering problems with the methods of Wiener and Kalman will be presented. Besides, connections will be established between the introduced concepts and traditional sound processing problems, such as ADPCM compression, morphing, dereverberation and noise reduction.

Abstract:
This seminary will present an architectural view of real time network music tools. This architectural model is being researched in a PhD thesis and resulted into the development of a network music tool called Medusa.
Medusa works with different audio and MIDI APIs and also uses different transport protocols. In a close future this tool will support also different addressing methidologies and OSC communication.
In this seminar we will present a discussion about Medusa architectural elements and how these choices can influence performance and utilization.

Abstract:
MOD is a linux-based LV2 plugins processor and controller. Musicians access it via bluetooth and setup their pedalboards by making internal digital connections between audio sources, plugins and audio outputs. After a pedalboard set is saved, it can be shared with other users at the MOD Social network. The software components are Open Source, which means you can also run it on any linux machine, not only on MOD hardware. The presentation aims to introduce the device to the community and discuss how its development may interact with plugins development and the development of the LV2 standard itself.
