Make a position-aware audio-walk, GPS-soundscape, local tourist guide or urban game with these Pure Data patches and authoring tool using MobMuPlat on your phone.
Currently the precision of floating point numbers in Pure Data is not enough (single precision) to triangulate the position exactly, this is why LocA discards the number before the decimal divider and just calculates with the floating point numbers as if they were integers. This works well if the area you placed your sounds doesn't span over coordinates.
