Abstract

An audio management application includes a recombiner and aggregation rules to manipulate and recombine segments of a musical piece such that the resulting finished composition includes parts (segments) from the decomposed piece, typically a song, adjustable for length by selectively replicating particular parts and combining with other parts such that the finished composition provides a similar audio experience in the predetermined duration. The architecture defines the parts with part variations of independent length, identified as performing a function of starting, middle, (looping) or ending parts. Each of the parts provides a musical segment that is integratable with other parts in a seamless manner that avoids audible artifacts (e.g. “pops” and “crackles”) common with conventional mechanical switching and mixing. Each of the parts further includes attributes indicative of the manner in which the part may be ordered, whether the part may be replicated or “looped,” and modifiers affecting melody and harmony of the rendered finished composition piece.
