Abstract: The present invention is a method and apparatus to control audio channels. Configuration registers configure usage of the audio channels. A plurality of channel logic circuits are coupled to the corresponding configuration registers to provide logic functions to the audio channels according to the configured usage.

Abstract: A CD player and three audio storage devices are coordinated using an interface(FIG. 1) which allows for a unique process of audio arrangement in which continuous intervals of audio are programed to be played from a CD in a specific order, each having a specific tempo and volume at which it is assigned to play. The process of forming an audio arrangement includes auditioning continuous intervals of audio directly from a CD in order to locate the precise position of desirable audio and then connecting these desirable intervals of audio so that each may be transmitted by this invention with a specific amount of timing with respect to the interval of audio that preceded it. After forming a program that specifies an audio arrangement, the CD player and the three audio storage devices can be used to further connect, blend, overlap, and otherwise mix the continuous intervals of audio read from one or several compact discs.
