Seminar by Lonce Wyse on Audio and Interaction
31 Oct 2013

Lonce Wyse, from National University of Singapore, gives a talk on 'Audio and Interaction through the Browser' on Thursday Oct 31st, 2013 at 15.30h in room 52.321

Abstract: Emerging web standards are just beginning to address the vast unrealized potential for sound on the browser platform. The first small steps toward a capable sound synthesis system have been made with the Web API, but there are many shortcomings in its performance and usability. With faster engines and good libraries, Javascript has become the lingua franca for client side programming, and is making inroads on the server side as well, though issues remain from the perspective of sound. In this talk, I will discuss recent developments of the web platform for sound, and present several projects from my lab that are moving toward creating an ecosystem of support for sound design, synthesis, interaction, collaboration, and performance with sound on the web.

Biography: Lonce Wyse received his PhD in Cognitive and Neural systems from Boston University in 1994 with a dissertation on pitch perception. He is now an Associate Professor of Communications and New Media at the National University of Singapore. He also directs the Arts and Creativity Lab and an Art/Science Residency Program at the NUS Interactive and Digital Media Institute. He is currently spending a semester sabbatical visiting the Music Technology Group at UPF.

ESSENTIA wins the Open-Source Competition of ACM-Multimedia

ESSENTIA, an audio analysis software library developed at the MTG, wins the Open-Source Software Competition of ACM Multimedia 2013, the worldwide premier multimedia conference that took place in Barcelona from October 21st to 25th 2013. 

The ACM Multimedia Open-Source Software Competition celebrates the invaluable contribution of researchers and software developers who advance the field by providing the community with implementations of codecs, middleware, frameworks, toolkits, libraries, applications, and other multimedia software. The criteria for judging all submissions include broad applicability and potential impact, novelty, technical depth, demo suitability, and other miscellaneous factors (e.g., maturity, popularity, student-led, no dependence on closed source, etc.).

ESSENTIA is an open-source C++ library for audio analysis and audio-based music information retrieval released under the Affero GPLv3 license. It contains an extensive collection of reusable algorithms which implement audio input/output functionality, standard digital signal processing blocks, statistical characterization of data, and a large set of spectral, temporal, tonal and high-level music descriptors. ESSENTIA is behind a number of commercial applications and has been used by many academic research projects. It is responsible for the audio similarity search functionality of

Participation to the IEEE AASP Challenge

Gerard Roma, Waldo Nogueira and Perfecto Herrera have participated in the Challenge for Detection and Classification of Acoustic Scenes and Events organized by the Audio and Acoustic Signal Processing comittee of the IEEE. One of their submitted algorithms obtained the best accuracy for the scene classification problem involving 10 different acoustic scenes. The MTG algorithm scored well above both the baseline and the other 16 submitted algorithms. The strengths of the approach lie in taking advantage of recurrence quantification analysis features computed from MFCC.
This research is presented during this week at the 2013 Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA), that is held in Mohonk Mountain House, New Paltz, NY, USA.

Seminar by George Tzanetakis on Physical Modelling
24 Oct 2013

George Tzanetakis, from University of Victoria (Canada), gives a talk on "Physical Modelling Beyond Sound Synthesis: three case studies" on Thursday October 24th at 15:30h in room 52.321.

Abstract: Physical modelling synthesis refers to a set of sound synthesis techniques in which the generated sound is computed as the output of a set of equations describing the actual physics of sound production of musical instruments. It can be viewed as a virtual simulation of the physical world. Physical modelling synthesis has many advantages including rich realistic sound, meaningful control parameters (such as the length of a string), and computational efficiency. One of the main challenges is that, similarly to actual acoustic music instruments, the control of physical models is not trivial as there are many regions of the parameter space that produce undesirable output sound. In this talk I will describe three case studies of combining concepts from different research areas (namely New Interfaces for Musical Expression and Music Information Retrieval) and physical modelling synthesis that attempt to address this control issue:

  1.  the SoundPlane which is a multi-touch pressure sensitive surface  that provides rich control possibilities
  2. the hybrid Gyil (an African Xylophone from Ghana) in which the buzzing gourds are physically modeled on a computer but the actual wooden bars are retained and
  3. Vivi, a virtual violinist that is taught how to bow a physical violin model similarly to how a beginner player learns to bow an actual acoustic violin.

Seminario sobre Cante Flamenco y Música Andalusí
16 Oct 2013

El miercoles 16 de Octubre a las 15:00h en la sala 55.309 del Campus de la Comunicación de la UPF tendremos una conferencia sobre el Cante Flamenco, impartida por José Miguel Díaz-Báñez y Joaquin Mora (Universidad de Sevilla) y otra sobre la Música Andalusí impartida por Amin Chaachoo (Tetouan-Asmir Center).

"Apuntes sobre el Cante Flamenco. El Caso de las Tonás"
José Miguel Díaz-Báñez y Joaquin Mora (Universidad de Sevilla)
Esta charla pretende ofrecer una introducción al cante flamenco pasando de lo general a lo particular, describiendo los aspectos generales que se requieren para realizar una incursión en el marco del flamenco y particularizando después en un grupo de "cantes",  conocidos como  "cantes por tonás", que se interpretan a capela y poseen una riqueza ornamental heredada de la cultura mediterránea.
"La Música Andalusí. Historia, Identidad y Características"
Amin Chaachoo (Tetouan-Asmir Center)
Se la conoce como Música andalusí, o Al-Ala, o Música Hispano-Musulmana o Música Arábigo-Andaluza. Se la define como la Música de Al-Ándalus, el patrimonio musical que los andalusíes descendientes de los expulsados de la península ibérica, conservaron y trasmitieron con cariño, amor, y sobretodo, con orgullo. Pero ¿cómo fue esa música? ¿Cómo se desarrolló en la Península? ¿Cómo llegó a ser una de las músicas más ricas y complejas? ¿Qué influencias y aportes contribuyeron en su formación? ¿Y cuál fue su destino en los países de acogida de los andalusíes?
Todas estas preguntas serán tratadas por Amin Chaachoo en la charla titulada “LA MÚSICA ANDALUSÍ. HISTORIA, IDENTIDAD Y CARACTERÍSTICAS” y que tratará de los distintos aspectos de esta música: sus componentes históricas, las fases de su desarrollo, su repertorio, sus tendencias, sus modos musicales, sus orquestas, etc. La conferencia incluirá además proyecciones de vídeo y audiciones de grabaciones que manifiestan y dejan ver la verdadera identidad de la música andalusí.
