Upcoming research seminars

Title: Machine listening and learning for musical systems

Speaker: Nick Collins, University of Sussex

Host: Perfecto Herrera

Date: Thursday June 7th, 2012, 15:30pm

Location: room 52.321, Roc Boronat building

Abstract: Musical articial intelligences are playing an important role in new composition and performance systems. Critical to enhanced capabilities for such machine musicians will be listening facilities modeling human audition, and machine learning able to match the minimum 10000 hours or ten years of intensive practice of expert human musicians. Future musical agents will cope across multiple rehearsals and concert tours, or gather multiple commissions, potentially working over long musical lifetimes; they may be virtuoso performers and composers attributed in their own right, or powerful musical companions and assistants to human musicians.

In this presentation we'll meet a number of projects related to these themes. The concert system LL will be introduced, an experiment in listening and learning applied in works for drummer and computer, and electric violin and computer. Autocousmatic will be presented, an algorithmic composer for electroacoustic music which incorporates machine listening in its critic module. Large corpus content analysis work in music information retrieval shows great promise when adapted to concert systems and automated composers, and the SuperCollider library SCMIR will be demonstrated, alongside a new realtime polyphonic pitch tracker.


Title: Percussive/Harmonic/Singing Separation on Monaural Music Signals

Speaker: Pedro Vera Candeas and Francisco Jesús Cañadas Quesada, Universidad de Jaén

Host: Emilia Gómez

Date: Friday June 8th, 2012, 11:00am

Location: room 55.410, Tànger building

Abstract: This seminar is divided into two parts. In the first part, a brief review of current percussive/harmonic/singing separation techniques is presented. In the second part, a preliminary unsupervised algorithm for separating percussive, harmonic and singing voice components from monaural polyphonic signals is shown. The proposed algorithm, based on a modified Nonnegative Matrix Factorization (NMF) procedure, does not require any training stages to distinguish between percussive, harmonic and singing voice bases because useful information from percussive, harmonic and vocal sounds is integrated into the decomposition process. In this process, NMF is performed by assuming that harmonic sounds exhibit spectral sparseness and temporal smoothness, percussive sounds exhibit spectral smoothness and temporal sparseness while singing voice sounds is characterized by a source/filter model in which the constraint “only one source is active” is integrated. Promising results are obtained when the proposed approach was compared using commercial real-world signals.

MAKE, PLAY, SHARE: The future of MusicTech

MTG is coorganizing, together with BMAT and Stromatolite Design Lab, a panel discussion in the frame of MIReS project which will take place at SonarPro next 14th June at 13.30 pm, just after the Companies' presentations at the Barcelona Music Hack Day.

The MIReS panel discussion intends to look into the future of the Music Industry from three perspectives: (i) Search & Discovery, (ii) Creativity and (iii) Rights Management. MIReS panel main aim is gathering first-hand feedback from relevant industry players which will serve as an input for the roadmap.

The list of panel speakers is as follows:

  • Alex Loscos, co-founder & CEO at BMAT
  • Scott Cohen, Founder and VP International at The Orchard
  • Hunter Williams, Senior Vice President Strategic Development/Distribution & Research Operations in SESAC
  • Michael Breidenbrücker, CEO at RjDj
  • Matthew Hawn, Vice President, Product at
  • Michela Magas, innovation catalyst at Stromatolite Design Lab

Master's projects exhibition at Sonar festival

MTG is organizing an exhibition at Sonar festival in order to promote the work of students that developed master's projects focused on audio. The works are the result of different masters from the UPF, including Sound and Music Computing, and Digital Arts from IdEC, and also a Phonos granted project (Prefall135).

One of the works that will be shown in the exhibition is The EyeHarp, by Zacharias Vamvakousis, currently PhD student in the MTG. The EyeHarp is an interesting instrument controlled by the movement of the eye, enabling to create music to those people with a motor disability.


All the projects will be displayed in the form of interactive installations, where music and sound will be central features. The exhibition will take place in the frame of the Sonar Pro section within Sonar Festival in Barcelona, from the 14th to 16th of June.

Barcelona Music Hack Day 2012

Music Hack Day is a two-day international event that convene enthusiasts of music, technology and creativity. This initiative presents an ideal ecosystem for networking, as its activities aim at creating new digital applications and projects based on music technology compatible with different devices (tablets, PCs, smartphones, etc.).

Specifically, the MHD involves the following activities:

  • Presentation of the most advanced music technologies by leader companies in the field of digital music.
  • a 24-hours hack session where participant will create innovative applications related to music technology.
  • Presentation of the applications created during the hack sessions.
  • Prizes for the best applications, awarded by MHD sponsors.

The MHD have shown to be an outstanding initiative to express the creativity of the music technology community, as it fosters innovation and the creation of new cross-platform applications. In the last 3 years, there have been more than 20 MHDs around the world. After its first edition in London 2009, it has been organized in cities such as Berlin, Amsterdam, Boston, Stockholm, San Francisco, Barcelona, New York, Cannes, Sydney and Montreal. The MHD is an exciting event that has gathered more than 2000 participants, who have developed hundreds of hacks with the support of more than 125 companies of music and technology.

The MTG has organized all MHDs in Barcelona, starting on october 2010. As in 2011, this year the MHD will be organized in collaboration with the SonarPro Festival, taking advantage of its important exposition (in 2011 it gathered more than 79.000 attendees, 833 companies and more than 1000 journalists from 515 media companies). SonarPro is a platform created by Sónar for visualizing, experimenting and getting updated with the latest news coming from the technology applied to music creation. That is why Sonar Pro is the perfect place to organize the Barcelona MHD; an environment where professionals and the general audience can learn about the latest technological innovations promoted by creative industries.

Due to the success of the MHD 2011, this year the event will take place in the Antic Teatre (main venue of Sonar Pro), fact that will allow to host up to 90 hackers and 10 artists to maximize the development of applications. Also, this year companies will be able to present all kind of technologies and hardware useful for creation of music Applications (not just APIs as in other MHD editions) and MHD attendees will get a welcome pack and a free pass for Friday night session at Sónar Festival.
