Seminar on repovizz at McGill

A seminar by Esteban Maestre, Marie Curie Fellow, McGill University + Universitat Pompeu Fabra;
With assistance by Quim Limona, Universitat Pompeu Fabra

DATE: Tuesday June 10, 2014 at 12:30pm
LOCATION: Room A832, New Music Building, 527 Sherbrooke Street West (CIRMMT)

ABSTRACTrepovizz is an integrated online system capable of structural formatting and remote storage, browsing, exchange, annotation, and visualization of synchronous multi-modal, time-aligned data. Motivated by a growing need for data-driven collaborative research, repovizz aims to resolve commonly encountered difficulties in sharing or browsing large collections of multi-modal datasets. At its current state, repovizz is designed to hold time-aligned streams of heterogeneous data: audio, video, motion capture, physiological signals, extracted descriptors, annotations, et cetera. Most popular formats for audio and video are supported, while CSV formats are adopted for streams other than audio or video (e.g. motion capture or physiological signals). The data itself is structured via customized XML files, allowing the user to (re-) organize multi-modal data in any hierarchical manner. Datasets are stored in an online database, allowing the user to interact with the data remotely through a powerful HTML5 visual interface accessible from any current web browser; this feature can be considered a key aspect of repovizz since data can be explored, annotated, or visualized from any location.

repovizz has been developed by the Music Technology Group of Universitat Pompeu Fabra in the context of large-scale research projects over the past few years, and now it is close to launching as beta. In this seminar we'll give an overview of the main capabilities of repovizz and its current state of development, followed by a short tutorial.

Sonar Festival 2014
12 Jun 2014 - 14 Jun 2014

Following the tradition, the MTG is behind a bunch of interesting events at Sonar Festival in Barcelona. For this year’s edition, that will take place from June 12th to 14th at Fira de Montjuïc, the MTG organises a great number of activities in the frame of the Sonar+D section.

MTG ACTIVITIES AT A GLANCE:

Music Hack Day (MHD) – Thursday, June 12th at 9AM to 13th at 6PM (Thu to Fri)

This year’s edition presents news and some changes, here’s a little flavour of what’s happening:

  • We count with the participation of 20 amazing and innovative technologies, like the kickstarter Mogees that turns daily objects into music instruments or Xth sense that allows the sonification of muscles (among others).
  • The Giant Steps European project plays an important role this year, sending two challenges to hackers and carrying out user studies to better understand the creative process that participants follow for the conceptualisation of their hacks.
  • Thanks to the collaboration with Made makerspace, we’re facilitating the onsite design and manufacturing of anything needed by hackers.
  • Wayra, the popular startup incubator, is also putting their two cents in the MHD by helping hackers preparing the 3’ presentations.

We are really grateful to our sponsors for helping us putting this edition on: 7Digital, Deezer, GiantSteps, Kiics, MusixMatch, Native Instruments, Patchblocks, Rdio, Sendgrid, TECNIO and Universal Music.

Check out the MHD website for further details

‘MTG & FRIENDS’ stand at Market Lab – from June 12th to 14th (Thu to Sat)

Exhibition of several installations and demos of our technologies, spin-offs, students and Phonos-MTG grant:

With the occasion of the 5th anniversary of the Music Hack Day initiative, we are also exhibiting in our stand some of the best hacks in MHD since its first edition in London 2009. The list of best hacks was carefully selected by a group of MHD veterans and experts and is as follows:

Together with the selection of the best hacks, people visiting the MTG stand will also have the chance to try new interactive musical interfaces based on brain activity. Two of the hacks developed within the Neuro-track in last year’s MHD will be expanded both in technological and business aspects. The two selected applications are Play your Mood, a music explorer based on the users’ emotional states, and BrainLoops, a musical interface for patients with locked-in syndrome.

These projects will be technologically supported by Starlab, whereas Barcelona Activa will provide business support to the selected creators. This initiative is promoted by KiiCS, and the Observatori de Comunicació Científica (OCC) of UPF.

Further details available here.

Giant Steps panel discussion – June 12th (Thu) from 18.30 to 19.30

Sergi Jordà, Principal Investigator of the project, will chair a panel discussion about several topics related to the Giant Steps project in which will participate two experts in electronic instruments design from Native Instruments experts and two Red Bull Music Academy musicians.

Check out the GiantSteps project website for further details

Spectral Diffractions – Mies van der Rohe pavilion – June 12th to 14th (Thu to Sat)

The SMC master student Antònio Sa Pinto collaborates with the artist Edwin van der Heide in the sound installation “Spectral Diffractions”.

new COFLA project

The MTG contributes to a new project on Computational Analysis of Flamenco Music (COFLA) coordinated by José Miguel Díaz Bañez (Escuela Técnica Superior de Ingeniería - Universidad de Sevilla) and funded by the Andalusian Government. The project started in February 2014 and has a duration of 4 years.

The MTG tasks will be devoted to of automatic transcription, similarity computation, automatic classification and synthesis of flamenco singing. Researchers involved are Nadine Kroher, Jordi Bonada, Sergio Oramas & Emilia Gómez.

New IEEE/ACM TASP paper on multi-feature beat tracking

Our article on multi-feature beat tracking for the IEEE/ACM Transactions on Audio, Speech and Language Processing is now available online! This is a work carried leaded by Jose R. Zapata for his PhD thesis in collaboration with Mathew Davies from the SMC group in Porto, based on the idea of combining different experts, represented by periodicity from different onset detection functions, for beat estimation. This is a simple and clever idea, already used to combine different beat tracking algorithms and evaluate the difficulty of the task, that has been integrated in a different method.

Zapata, J. R., Davies M. E. P., & Gómez E. (2014). Multi-feature beat tracking. IEEE/ACM Transactions on Audio, Speech, and Language Processing. 22(4), 816 – 825. RTF, Tagged, XML, BibTex, Google Scholar


Abstract: A recent trend in the field of beat tracking for musical audio signals has been to explore techniques for measuring the level of agreement and disagreement between a committee of beat tracking algorithms. By using beat tracking evaluation methods to compare all pairwise combinations of beat tracker outputs, it has been shown that selecting the beat tracker which most agrees with the remainder of the committee, on a song-by-song basis, leads to improved performance which surpasses the accuracy of any individual beat tracker used on its own. In this paper we extend this idea towards presenting a single, standalone beat tracking solution which can exploit the benefit of mutual agreement without the need to run multiple separate beat tracking algorithms. In contrast to existing work, we re-cast the problem as one of selecting between the beat outputs resulting from a single beat tracking model with multiple, diverse input features. Through extended evaluation on a large annotated database, we show that our multi-feature beat tracker can outperform the state of the art, and thereby demonstrate that there is sufficient diversity in input features for beat tracking, without the need for multiple tracking models.
