AÂ short report on the workshop at Transmediale 2010 which went very well considering the various weather conditions in Berlin this week. Udo Noll the creator and developer of Radio Aporee Maps has revived the possibility of integrating a GPS locating function that works with the main website. A small application loaded onto a GPS enabled mobile phone can track your movement when enabled. Your path is then recorded and when played back, is synchronized with the existing sounds on Radio Aporee Maps. The different data layers (sounds, GPS track) are then mixed to create something of a fictional “sound walk”. While the recorded paths may stay the same the mix of sounds will continually change as new sounds are added to the map. To hear some examples, visit the Radio Aporee Maps Mobile page. Click on any of the files with ‘ctm workshop’ in the title and see some paths. Also, a number of new sounds were added during the week, particularly around Alexanderplatz, Rathauspassage and Klosterstrasse by myself and other workshop participants.
