Soundcities was the first online open source database of city sounds and soundmaps from around the world, using found sounds and field recording. There are now thousands of sounds from around the world on the website. This project allows the audience the possibility to remix the hundreds of samples recorded from cities around the world in an online database. The sounds can be listened to, used in performances on laptops, or played on mobiles via wireless networks.
