Abstract: A digital audio processing system determines characteristics of an electronic presentation to generate a musical composition that is unique to the electronic presentation by adjoining digital audio stems in accordance with the characteristics of the electronic presentation. Embodiments enable a user to define an order for displaying images and a level of importance of the images with respect to one another. For example, the user may designate a specific one of the multiple images as a “highlight image” for emphasizing during the electronic presentation. Then, the system may arrange numerous musical segments adjacent to one another so that the intensity (e.g., energy level) of a resulting musical composition coincides with key events (e.g., a highlight image being shown) of the particular electronic presentation. The intensity of a particular musical segment may indicate a relative note structure density as compared to other musical segments that are defined within the stem data.

Abstract: Described herein is a system for automatically mixing music. An ordering component receives information regarding a set of songs, obtains pre-analyzed metadata about songs in the set of songs, and, based upon the pre-analyzed metadata orders the songs into a mix based upon an analysis of beats-per-minute and song key. A cue point component, based upon a user preference, selects one or more cue points from the pre-analyzed metadata for transitions into and/or out of the songs in the mix. A transition component, based upon the user preference and information derived from the pre-analyzed metadata for each section of a particular song, configures transitions between songs in the mix. The system can store metadata about the mix for playback.
