Abstract
A system for selectively combining numerous audio tracks recorded on an optical disk, including subtracting, by phase inversion, particular tracks from a full mix. Each track might contain a recording of an individual instrument, or a group of instruments. When the disk is played, the player provides the user with menu choices--which tracks should be played and mixed together. In this way, the user can create his/her own orchestral mix, perhaps omitting an instrument in a "play along" application, or playing one instrument alone to be mimicked for practice purposes. The disk further includes track definitions in multiple languages so that the same disk can be distributed throughout the world, with menu choices being given in a language selected by the user.
