Abstract
Small, high-quality soundfiles are algorithmically recombined and their behavior altered to create rich, non-looping sound environments. These environments consist of sound effects as well as musical tones; for example, the sound of a single water drop or a single ocean wave can be replicated and regenerated according to algorithmic rules to create a long-running non-looping sound effect. Sonic parameters such as pitch, start time, intensity, and apparent spatial location are given initial values which are then changed in realtime via genetic algorithms to generate new values. When applied in Web-based 3D environments (e.g., VRML, Java3D, etc.), the present invention dramatically reduces the necessity for downloading large soundfiles. The present invention may also be used in real-world systems to produce long-running, interactive, non-looping sound environments. Applications of the present invention include awareness systems, entertainment systems, real/virtual interplay, and long-term auditory monitoring and display.
