24r was a collaborative sound piece designed by tsonami&arsomnis, where 24 recorders/artists/people around the world recorded one hour of their soundscapes.

All recordings were to be carried out during the same day, September 21st 2011, following GMT standard time, for the day's entire duration.

While recording each participant reveals himself in the soundscape by playing a sound alternated with silence during 2:30 minutes. The sound could be produced by any means. A 60' small pulsing derivative was produced when all these sounds were pasted. 

24r was presented at the VI Tsonami Sound Art Festival.
