Abstract: A method of sound synthesizing in which characteristics of a plurality of harmonics of a sampled sound are first absorbed into a wave-table so that a sound can be synthesized from a reduced number of harmonic envelops for efficient processing while preserving fidelity. This method is particularly good for synthesizing the sound of a string instrument.

Abstract: A coating system and method of applying coatings includes applying a first coating having an ultraviolet (UV) indicator therein to an area. The area visually inspected with a UV light and defects are remedied until the area passes the visual inspection. A second coating without a UV indicator is applied over the first coating and visually inspected, with the first coating being visible with a UV light at portions wherein the second coating does not cover the first coating. The second coating is reapplied to portions of the area not passing inspection until the second coating passes inspection. The system also includes three, four or more coating layers in some embodiments with layers having a UV alternated with layers without a UV indicator. The indicator is an inert substance that remains stable to allow for periodic visual inspection over the life of the coating.
