Seminar by Daniel Erro on voice conversion

Next thursday, January 22nd 2008, Daniel Erro will give a seminar with the title "Voice conversion: state of the art, recent improvements and remaining challenges" at 3pm in the França Auditorium.

Voice conversion, which consists of modifying the voice of a speaker to be perceived as that of a different specific speaker, is probably the most complex type of voice transformation. Its development opens the door to very interesting applications: building multi-speaker or multi-emotional speech synthesis systems, creating special voices or virtual clones of famous people for videogames, films, toys, chat rooms, speaking aids for people suffering from voice pathologies, etc. During the seminar, I will give an overview of the voice conversion world. I will talk about the techniques applied by state-of-the-art systems and I will focus mainly on the work carried out at UPC to overcome some of the traditional limitations of voice conversion: the quality degradation and the lack of flexibility in terms of training requirements. Finally, I will list some of the future challenges for researchers in this area and I will show some preliminary results of my current work at the Aholab group (UPV/EHU).

Erro received the Telecommunication Engineering degree from the Public University of Navarra (Pamplona, Spain, 2003) and the PhD degree from the UPC (Barcelona) in june 2008. He is currently working as a post-doctoral researcher at the Aholab group (University of the Basque Country, Bilbao). He is interested in everything related to voice transformation and conversion, signal models for speech and music waveform analysis, modification and reconstruction, and speech synthesis.

LoopMash by Steinberg, developed in collaboration with the MTG, is announced

At the NAMM show, one of the world’s largest music trade shows, Steinberg Media Technologies GmbH has announced the release of Cubase 5, the newest version of its well known music production software. In cooperation with Yamaha Corporation, the Music Technology Group (MTG) of the Universitat Pompeu Fabra in Barcelona played an important role in the research and development that led to one of its new features, LoopMash, a powerful creative tool for slicing and instant re-assembling of sound material.

LoopMash originates from a joint research project between MTG and Yamaha, a project that aimed at developing the next generation of music production tools. In particular it focused on the manipulation of sounds in a way similar to the creation of mosaics, a process that is now known as audio mosaicing. With the techniques developed, existing sound material can be recycled and recomposed using computational tools; first by automatically extracting sound snippets from existing music, then analyzing the similarity between them, and finally recombining the snippets in musically relevant ways.

The outcome of the project was a software prototype that used this technique as a musical instrument, remixing the snippets intelligently and automatically, typically from drum-loops, under interactive control of the musician. This prototype showed that potential of these techniques for making music based on reusing existing sound material and thus giving deejays and contemporary electronic musicians a new level of control.

In a team effort, MTG, Steinberg and Yamaha successfully have converted the resulting prototype into a real product. LoopMash is now a VST3 Instrument, integrated into Cubase, and thus adding to Cubase a unique and innovative way of creating music.

Graduate programs on SMC for 2009-2010
The registration for the official Master in Sound and Music Computing 2009-2010 is now open and the first registration period ends on January 30th, 2009 (check application calendar).

A part from the SMC Master, in the academic year 2009-10 the ESMUC and the UPF will jointly offer specialized professional programs in the area of Sound and Music Computing. Specifically in the period September to December 2009 an intensive course on Music Production Technologies and Techniques will be offered and another one on Interactive Music Systems Design will be offered from January to April 2010. The official information about these courses should be available in January 2009.

Demos and software from the finished EmCAP project
EmCAP (Emergent Cognition through Active Perception) was an EU research project that finished on September 2008 in which the MTG participated. The goal of the project was to investigate cognitive behaviour in artificial systems and its emergence by interacting with the environment. The project finished with a public workshop at the end of september 2008 in which most of the outcomes of the project were presented. The talks of the workshop are available as videos.

Recently the consortium has made public here all the demos and software that were created for the project. The MTG has contributed with the Emerge Demo developed by Richard Marxer, with the Real-time What/when Expectation System developed by Amaury Hazan, with the Statistical Learning Experimenter Package developed by Amaury Hazan and Piotr Holonowicz, with a number software libraries available in here, and data collections available here.

Seminar by Rafael Ramirez at City University London

Rafael Ramirez will give a seminar with the title "The ProSeMus Project: from Expressive Performance to Cognitive State Decoding"as part of research seminar of the Music Informatics Research Group of City University London on Monday December 15th 2008.

Abstract: In this talk we present current research carried out within the ProSeMus project. In particular, we present research on (1) expressive music performance computational modeling using machine learning techniques, (2) style-based automatic performer identification, and (3) automatic instantaneous cognitive state decoding based on a person functional magnetic resonance imaging (fMRI) data. We discuss the results and describe some areas of future research.

New research project: Music 3.0
The MTG has started a new research project funded by the program Avanza Contenidos of the Spanish Ministry of Industry, Turism and Trade. The main goal of the project Music 3.0 is to develop an experimental web-based system for music creation, interaction and socialization. Such system should integrate the most recent technologies of the Web 2.0, advanced on-line tools for music creation, and large sound and music repositories. For such system there will be a need to develop social networking models specific for music, models for the treatment of music content and also models for the creation of new content.

Updated version of SMS code
Rich Eakin, Master student working at the MTG, has updated the open source Spectral Modeling Synthesis C software library originally developed by Xavier Serra for his PhD thesis in 1989. The library, called libsms, is distributed with source code and under GNU license and it has been tested with Ubuntu. Rich has also added a Pd (Pure Data) library of externals alongside libsms to be used for real-time applications.
