Place: Auditório do CCSL, IME/USP
Abstract: In this talk we present the SuperCopair package, which is a new way to integrate cloud computing into a collaborative live coding scenario with minimum efforts in the setup. This package, created in Coffee Script for Atom.io, is developed to interact with SuperCollider and provide opportunities for the crowd of online live coders to collaborate remotely on distributed performances. Additionally, the package provides the advantages of cloud services offered by Pusher. Users can share code and evaluate lines or selected portions of code on computers connected to the same session, either at the same place and/or remotely. The package can be used for remote performances or rehearsal purposes with just an Internet connection to share code and sounds. In addition, users can take advantage of code sharing to teach SuperCollider online or fix bugs in the code.

Abstract: In games, a common strategy to provide a more engaging player expericence is to allow the game's soundtrack to react, in real-time, to the happenings inside the virtual universe, since that provides a complementary interaction to the user beyond the conventional expression through visual aspects. However, given the non-linearity of this audiovisual media, many challenges of artistic, practical and technological order arise from this dynamic approach. In this work, we look for a middleware solution capable of mitigating such complexities, specially having composers and sound designers in mind as final users.

Date and time: Monday, June 29, 2015 - 13:00
Place: Auditório do CCSL, IME/USP
Abstract:

In this talk we will present an application that can send all events from any sensor available on an Android device using OSC and through Unicast or Multicast network communication. Sensors2OSC permits the user to activate and deactivate any sensor at runtime and has forward compatibility with any new sensor that may become available without the need to upgrade the application for that. The sensors rate can be adjusted from the slowest to the fastest, and the user can configure any IP and port to set receivers for OSC messages. The application is described in detail with some discussion about Android device limitations and the advantages of this application in contrast with so many others that are available on the market. The audience is invited to use the application during the demonstrations.

Place: 144-B
Abstract:

In this seminar we present the paper "A Influência do Conteúdo Espectral na percepção de acordes Consonantes e Dissonantes e seu reflexo na Atividade Cerebral" (The Influence of Spectrum Content in the Perception of Consonant and Dissonant Chords and its reflex on Brain Activity) developed in partnership with Antonio Goulart and Micael Antunes, that tackles the basis for the musical consonance analysis and its relationship with the spectral content of chords present in the tonal system and, based on this, propose an experiment that explores through electroencephalography a relation between the harmonic nature of musical instruments and the brain response to the auditory stimulus.

Abstract:

Audio processing applications can and do suffer from overload situations. This results in unwanted sound events: strong distortions, clicks and interruptions. For practical reason it is not always possible to resolve such problems always with more computational ressources. In this talk we will present ideas which try to take another approach. We want to flexibilise the computational costs of the elements of the audio processing chain to control them dynamically thus avoiding overload situations of the system. This flexibilization is realized by means of a trade-off between computational costs and the quality of the audio output.

In this seminar we will present an introduction to the subject as well as our first ideas and some preliminary proposals of our research.
