Abstract: A system (200) for processing a sound signal (212) that allows dynamic customization of perceived spatial positions and sound qualities of sound components associated with the sound signal (212). The system provides apparatus for processing a sound signal (212) that includes an input to receive the sound signal (212), a sound unmixer (204) coupled to the input to receive the sound signal (212) and unmix at least one sound stream (216) from the sound signal (212) based on at least one unmixing instruction (214), and an output coupled to the sound unmixer (214) to output the at least one sound stream (216).

Abstract: A method and apparatus for an audio scrubbing system for synchronizing audio to an asynchronous clock while preserving pitch utilizes a phase-vocoder to implement time-scaling without pitch-shifting.

Abstract: A movable support for positioning a left/right hand during the application of polish to a user's four fingernails in the use of which the user's thumb on an adjacent support surface steadies the four-finger support against movement from the polishing position.
