Hands-on session


“do we have time?”

“it’s working now”

We walk the talk


The team had first contacts with GPS datalogging, strange GHz sounds, bats not flying, etc. and a range of different recording options. I downloaded their walk and Bram -our wizard for on-the-fly-speed-coding- did some magic.

Wow. We have a first augmented animated walk. Above you see the static screenshot, our appetizer of the day.

Feel free to comment! That’s what blogs are for.

I am looking forward to our today’s hand-on session to get deeper into the thing … maybe some video would be cool …


Pictures and sounds…

As a reminder, here is the set of sounds on freesound, tagged with the tag “smc2009”:

A geotagging “shortcut” to porto:

Update from natural interactive walking in Porto group


during the second day we have been working on finding some interesting spots in Porto to record. We have discussed the various approaches and alternatives and what each group member was interested on, together with a common strategy to achieve a satisfactory end result till the deadline tomorrow.



Automatic classification and segmentation of Sound of Porto

Hi all,

Our workshop group is working on sound retrieval, exploring how the current technology available for signal analysis of musical sound could be used also to understand important features of non-musical sound (natural, mechanical, voices, non melodic events). We want to explore how to compose soundscape using classification and segmentation information to organise database material for the soundscape generation, or design a sort of feedback control through sound content analysis to modify the generating soundscape.

We also want try to use a tangible table user interface for tracking fiducial markers and for finger tracking to built and interactive application for soundscape composition and spatialisation starting for the content information obtained with the signal analysis techniques.

Right now we have organised recording query in the city, we have choose different part of the city for each of us trying to collect as more as possible sound variety in order to create several interesting classification class to be studied with the Marsyas. A framework aims at signal content analysis.

Next step for today will be hearing, editing, and think about the collecting material to create the classification class to find sound features similarities through the Marsyas framework.

Robotic Gamelan: Nicole, Joe, Matthew

We are interested in combining Porto’s ambient sonic landsape with the challenge of making the robotic gamelan sound “not gamelan-ish.” We are designing an installation where an analysis of sound files featuring Porto’s wind and waves (its natural soundscape) combined with recordings of the sounds of its traffic (its man-made or artifical soundscape) drives the gamelan to generate its own soundscape in the acoustical environment of the Casa da Música. The system will be open to user interaction and listeners will have an opportunity influence the soundfiles under analysis and the mapping between the analysis and the robotic response.

Our group’s work is currently divided into three areas: 1) designing the user interaction for the system, 2) choosing the soundfiles and the method for their analysis, and 3) the creation a set of tools for high-level control of the instrument itself. We’ve decided to begin with an open design process guided by the movement of visitors through the Casa da Música, the discovery of interesting source recordings and promising high-level control sets. Once we are able to make observations based on these explorations we’ll drawn inspiration from them and select interesting aesthetic areas for concentration and refinement.

Thanks in advance to Stephan, as we’re beginning by given a listen to his vast recording repository and then branching out from there.
