Galata Electroacoustic Orchestra

The MTG participates in the Galata Electroacoustic Orchestra project, a European Erasmus Intensive Programme coordinated by Conservatorio Niccolò Paganini. The institutions partnering in this project are Istanbul Bilgi Üniversitesi (Istanbul), Istanbul Teknik Üniversitesi (Istanbul), Universitat Pompeu Fabra (Barcelona) and Conservatorio Statale di Musica “G.P. da Palestrina” (Cagliari)

The GEO IP project (Galata Electroacoustic Orchestra) is inspired by the historical relations between Genova and Istanbul. The first edition of GEO is taking place in Genova between the 15th and 26th of July, 2013.

A total of 7 MTG PhD students and SMC master students are participating in workshops, labs and lectures about traditional music of the three involved countries (Turkey, Spain and Italy), focused on ethnomusicological, technological, performing and compositional disciplines.

The general objectives of GEO IP are:
- To create the Galata Electroacoustic Orchestra, a small group orchestra based on an idea of live collective composition;
- To merge of the Western Classical tradition of score based music and the Improvisational techniques, in particular of Turkish Maqam Music.

The project also includes a final concert of the Galata Electroacoustic Orchestra at old port of Genova on Friday 26th at 9PM.

Seminar by Julio José Carabias on audio to score alignment
13 Jun 2013

Julio José Carabias Orti from University of Jaén will give a seminar titled "RealTime Audio to Score Alignment System using Spectral Factorization and Online Time Warping" on Thursday, June 13th, at 15.30 in room 52.321.

Abstract:
In this work, we present a realtime score follower based on spectral factorization and online Dynamic Time Warping (DTW). The presented system has two separated stages, preprocessing and alignment. On the first one, we convert the score into a reference audio signal using a MIDI synthesizer software and we analyze the provided information in order to obtain the spectral patterns (i.e. basis functions) associated to each combination of notes. These basis functions are learned from the synthetic MIDI signal using a method based on NMF with Beta-divergence where the gains are initialized as the ground- truth transcription inferred from the MIDI. On the second stage, a realtime signal decomposition method with fixed basis functions per combination of notes is used over the magnitude spectrogram of the input signal resulting in a distortion matrix that can be interpreted as the cost of the matching for each combination of notes at each frame. Finally, two online DTW approaches are proposed to find the path with the minimum cost and then determine the real duration of the MIDI states. Our system has been compared to other state-of the-art systems obtaining reliable results.

Biography:

Julio José Carabias-Orti received the M.Sc. degree in computer science and the Doctor of Science degree from the University of Jaen, Jaen, Spain, in 2006 and 2011, respectively. He is currently working as a research fellow at the Telecommunication Engineering Department, University of Jaen. His research topics include automatic music transcription, sound source separation, factorization algorithms and machine learning.

Award by the Japan Institute of Invention and Innovation (JIII)

Dr. Jordi Bonada has been awarded with the 'National Commendation for Invention' by the Japan Institute of Invention and Innovation (JIII) for one of the patents obtained as outcome of a joint research work in singing voice synthesis carried out by the MTG (UPF) and Yamaha Corp. in Japan. Dr. Bonada, one of the inventors and the responsible person of this R&D project, has been invited to the awards ceremony which will take place on June 18, 2013 in Japan.

This Commendation has been held since 1919 by JIII for the purpose of contributing to the progress of science and technology and the development of industry in Japan. This award intends to commend persons who have accomplished extremely excellent inventions full of originality, rendered distinguished services in the working of inventions and greatly contributed to the promotion of excellent technology and to the guidance and development of human resources.

This award is a recognition to the research collaboration between the MTG and Yamaha Corp. initiated 15 years ago. As a result of this collaboration there is a great number of patents (more than 40) as well as commercial products such as the popular Vocaloid which represents an entirely new music industry paradigm.

Seminar by Jordi Navarra on auditory processing
16 May 2013

Jordi Navarra, from Fundació Sant Joan de Déu, gives a talk on "Temporal & spatial re-encoding of sound" on Thursday May 16th 2013, at 3:30pm in room 52.321.

Abstract: Our perception is always a reconstruction of our surrounding World. Two of best examples to illustrate this idea are the 'temporal recalibration of sensory signals' and the 'spatial encoding of pitch'. Regarding temporal recalibration, we showed that our response to auditory stimuli can speed-up or slow-down after adaptation to audiovisual asynchrony, perhaps reflecting that the processing of auditory signals accommodates to the visual processing time (see Navarra et al., PNAS, 2009). This may be due to the fact that visual information provides the perceiver with a better estimate of the time of occurrence of distant (audiovisual) stimuli. Regarding the spatial encoding of pitch, I am currently investigating how the "ups and downs” (in pitch) in complex auditory signals such as music or speech are remapped into spatial coordinates. In a recent study, we demonstrated that the spatial representation of high and low tones embedded in melodies can influence the spatial processing of visual stimuli.

Music and sounds from the brain
23 May 2013

On Thursday May 23rd, scientists who study the brain, along with sound researchers and musicians, will join together in the Centre de Cultura Contemporània de Barcelona (CCCB) to offer one of the most innovative and exciting shows of recent times. The human brain responds to the melody and rhythm by changing connections between its neurons, and now science and technology allow us to see this process in real time in the show the “Brain on Stage".

During the event, we will present this year's Music Hack Day with focus in Neuroscience and also listen to some of the "Sound Fictions” created by more than 300 young adults in the workshops "Sounds, science and technology" in the frame of the Sons de Barcelona project and follow up the activities that are carried out in the KiiCS European project (Knowledge, Innovation and Incubation in Creation for science) that explores how to encourage innovation and creation by the intersection between art and science.

The event is organized by the Observatori de Comunicació Científica (OCC) from Universitat Pompeu Fabra (UPF) in collaboration with Synthetic Perceptive, Emotive and Cognitive Systems (SPECS) and the Music Technology Group (MTG) from the same university, Phonos Foundation and Institut Municipal d’Educació de Barcelona (IMEB). The workshops "Sounds, science and technology" have the financial support of Fundación Española para la Ciencia y la Tecnología (FECYT).
