One Hundred Thousand Landscapes is a multi-channel sound installation that creates a perpetually evolving sonic landscape from an online database of over 100,000 sound samples. The system searches for sounds that fit certain descriptions to create a sonic environment. This ruleset functions as the “DNA” of the piece, providing an organizing principal to the evolution of the sonic environment. In addition, the system also informs its own progression as each new sound influences the next using spectral descriptors of the sound file to search for other sound files that sound similar.
