Look at them, with their recorders and headphones, running around, asking people to perform actions so they can record them. They are like us, but smaller! ;P
So we dedicated a full session for participants to learn how the recorders work and practice their new acquired knowledge around the school. This was a preparation for the task of taking the recorders home, and go on recording sounds from their daily life.
And they have collected quite some interesting sounds indeed. Below you can hear a few of them, and don’t forget to visit our Freesound SonicSnaps pack for the rest of them: http://www.freesound.org/people/thecityrings/packs/10902/
Oh! we did not remove , from the sounds, the voices of the participants when they announce what they are going to record. Of course we will not use those voices during the Sonic Postcard composition, but we found it could be interesting for you to hear some tiny Spanish and Catalan voices at work.
