News and Events

Registration for the Neuro Music Hack Day is now open!
15 Apr 2013 - 15 May 2013

In addition to the regular Music Hack Day track, this year’s BCN Music Hack Day includes a special Neuro-track that aims at providing a set of useful tools, hardware and APIs to encourage hacks that bring together music, brain signals and other physiological sensors.

Through this approach, we want to encourage the creation of new ways of music creation and interaction using physiological signals. In the same line, the MHD will offer a pre-event introductory workshop on June 12th where the different hardware devices (BCI, Enobio, and other physiological sensors), which will be made available to participants of the MHD, and the related APIs will be presented to all participants interested on developing hacks within the neuroscience track.

In the registration form you can either choose the Regular Music Hack Day Track or the Neuro Music Hack Day Track, depending on your background and/or hacking interests. Space for this event is limited so we can't guarantee everyone a spot. We'll try to keep things on a first come, first served basis, whilst at the same time ensuring that we have a good mix of people who are prepared to build something or contribute in some other valuable way. We'll send out a confirmation email as the date approaches and will accommodate as many hackers as we can.

Freesound: 8th anniversary

Today is the 8th anniversary of Freesound! Congratulations to the researchers, developers, moderators, donors and users who have been and are part of this project for the success achieved so far. Thanks to the collaboration of this great community we have now more than 160.000 free sounds from all over the world.

Freesound was started in 2005 in our research group. One of the first aims behind it was to create an open repository of sounds to be used for scientific and artistic research, but quickly became a very popular site used by a wide variety of people to share sounds and the experiences around them. Users upload sounds recorded or created by themselves and share them under Creative Commons licenses. The sounds in Freesound have good quality, are free and legal, so professionals from different fields (cinema, music, videogames, software...) as well as amateur users, use them in their works.

Freesound has now 3.5 million registered users around the world, about 40.000 unique visits a day, and the total number of unique visits in those eight years has been more than 57 million, coming from almost all the countries of the world.

There are many successful usages of the sounds in Freesound, for example in the movie Children of Men and in a song of the internationally known band The Prodigy. Freesound has received several awards, such as a BMW award, a Barcelona City award and a Google research award twice. But what is most important, during all those years users have shared really amazing sounds. Find the opinion of the community about the coolest sounds on Freesound:

The interest for sharing sounds keeps growing and the community of active users of Freesound is also growing. For the MTG, Freesound offers an exceptional framework with which to carry research in the context of semantic web technologies. But we are specially proud of being able to offer a very useful service to the society.

TONAS: a new dataset of flamenco a cappella sung melodies with corresponding manual transcriptions

As a little Friday gift, we're glad to announce the release of a new dataset of flamenco singing: TONAS

The dataset includes 72 sung excerpts representative of three a cappella flamenco singing styles, i.e. Tonás (Debla and two variants of Martinete), together with manually corrected fundamental frequency and note transcriptions.

This collection was built by the COFLA team in the context of our research project for melodic transcription, similarity and style classification in flamenco music.

Further information about the music collection, how the samples were transcribed and by who, is available on the dataset website, where you can of course download the audio, metadata and transcription files.

We hope that you find this collection useful, whether for automatic transcription of the singing voice or any other research topic (e.g. pitch estimation, onset detection, melodic similarity, singer identification, style classification), and we hope this dataset will increase the interest of our scientific community on the particular challenges of flamenco singing.

We would be very interested to receive your feedback.

Best regards,

The COFLA team

Barcelona Music Hack Day 2013 - Neuroscience and Music (Special Track)
13 Jun 2013 - 14 Jun 2013

Barcelona Music Hack Day 2013
13th - 14th June 2013 - Sonar Festival (Sonar+D)

Neuroscience and Music (Special Track)

Get the chance to develop a new application interfacing music with the brain at the Barcelona Music Hack Day 2013!! We are looking for a new connection between neuroscience and music.

The Music Hack Day (MHD) is a 24 hour hacking session in which participants conceptualize, create and present their projects. Any Music Technology, i.e. software, mobile applications, hardware, artworks, web development, goes as long as it is music related. The MHD has been a great way to demonstrate the creativity around music that comes from the tech community. The past three years have seen more than 20 MHD events taking place around the world. Starting in London, it has spread across the world to Berlin, Amsterdam, Boston, Stockholm, San Francisco, Barcelona, New York, Sydney, Montreal... The MHD has gathered over 2000 participants, building hundreds of hacks and with over 125 music and tech companies supporting the events. The Music Technology Group (MTG) of Universitat Pompeu Fabra (UPF) has hosted the MHD in Barcelona since 2010, and currently it is organized in the frame of Sónar festival.

With the support of the EC funded project KiiCS (Knowledge Incubation in Innovation and Creation for Science) this year the Barcelona MHD will include a special neuroscience track that will aim at providing a set of useful tools and APIs to encourage hacks that bring together music, brain signals, Brain-Computer Interfaces, and other physiological sensors. Through this approach, we want to encourage the creation of new ways of music creation and interaction. In the same line, the MHD will offer a pre-event introductory workshop where the different hardware devices (BCI, Enobio, and other physiological sensors), which will be made available to participants of the MHD, and the related APIs will be presented to all participants interested on developing hacks within the neuroscience track.

This initiative is lead by the Music Technology Group (MTG) in collaboration with the Science Communication Observatory at UPF through the KiiCs project, and it is supported by the research group Synthetic, Perceptive, Emotive and Cognitive Systems (SPECS), also from UPF, and by Starlab Barcelona SL.

Seminar by Jordi Janer on music signal source separation

Jordi Janer, from the MTG, gives a talk on "Methods for Music Signal Source Separation of Professionally Produced Recordings" on Thursday February 14th 2013 at 15:30h in room 52.321 of the Communication-Poblenou Campus of the UPF.

This presentation addresses the topic of Music Signal Source Separation. We show the outcome of an industrial joint-research project at the Music Technology Group of UPF. From an initial goal of removing the lead instrument from a professionally produced music recordings, we worked on a general framework for music signal modeling and separation. These methods introduce some novelties over the state-of-the-art, extending on approaches such as Non-negative Matrix Factoriztion (NMF). We present timbre classification for predominant pitch detection, vocal residual treatment, monophonic and polyphonic polytimbral source/filter models, harmonic/percussion separation. Our methods can be grouped in two different categories depending on the field of application: a) low-latency/low-computation and b) high-latency/high-computation. Several demos and potential uses of music source separation will be introduced in our talk.

Jordi Janer is researcher at the Music Technology Group of the Universitat Pompeu Fabra in Barcelona. His research interests cover: audio signal processing with a focus on the human voice, source separation, applications for real-time music interaction and environmental sound analysis and soundscape modelling. Graduated in Electronic Engineering (2000), he started his career as DSP engineer at Creamware GmbH, (Germany, 2000-2003), designing and developing audio effects and virtual synthesizers. Joining later the UPF, he obtained the PhD degree in 2008. As a visiting researcher, he stayed at McGill University (Canada, 2005) and at Northwestern University (USA, 2009). His activity as a researcher and project manager in the past years involves various public-funded research projects (2004-2013), and joint-research collaborations with Yamaha Corp. (Japan). He is also cofounder in 2011 of Voctro Labs, a spin-off company specialized on voice processing solutions for the audiovisual media industry.

Seminar by Geoffroy Peeters on annotating MIR corpora

Geoffroy Peeters, from IRCAM, will give a seminar on "Annotated MIR Corpora, MSSE search engine for music, Perceptual Tempo" on Thursday, January 24th, at 3:30pm in room 52.321.

In this talk I will focus on three recent topics studied at IRCAM.
The first concerns a proposal for the description of annotated MIR corpora. Considering that today, annotated MIR corpora are provided by various research labs or companies, each one using its own annotation methodology, concept definitions, and formats, it is essential to define precisely how annotations are supplied and described. We propose here a proposals for the axis against which corpora can be described.
The second concerns our experience in integrating music indexing technologies in a third-party search and navigation engine (Orange MSSE search engine). We explain the work performed for this in terms of – choice of the technology, - development of annotated corpora for training the systems, - HIM development, user tests.
The third concerns the estimation of perceptual tempo and the reduction of the so-called octave errors of tempo estimation algorithms. Using the data from Last-FM perceptual experiment, we model the relationship between a set of four audio features to the perceptual tempo using a GMM Regression technique. We show that this technique allows outperforming current tempo estimation algorithms.
