The sound-spatial environments integrate into a wider frame of acoustic topology and data visualization concepts. Artificial landscapes are formed, that sometimes seem to mimic the corresponding natural ones, such as valleys or ocean surfaces, or, due to the change of scale they belong, micro-landscapes that are not visible to the naked eye. They are a sort of cartography of sound. They are based on sound data analysis of certain areas, musical compositions, or experimental modulations of a single sound source (like a musical instrument) into such ways that affect drastically its visualization. The strategy being used here begins with the mapping of sound on to a two-dimensional surface whose, length and width (two spatial values) are replaced by time (duration of sound) and frequency (two properties of sound). Then, based on the volume data of the sound throughout the frequency range and duration, the 2-dimensional mappings are extruded so the final surface obtains a third dimension. Using different approaches next, formatting these surfaces, a new series of surfaces, objects and shells are produced where sound becomes concrete, tangible and accessible.
