A method to author music. The method includes generating, based on a collection of media clips stored on a device, an audio component for an audio/video (A/V) presentation, determining a plurality of locations within the audio component where a beat, onset, segment boundary, or stinger occurs within the audio component, selecting a particular location in the plurality of locations as a transition location, generating, based the collection of media clips and the transition location within the audio component, a video component for the A/V presentation, and generating the A/V presentation based on the audio component and the video component.

Synchronizing audio and video components of an automatically generated audio/video presentation

Some embodiments provide an audio authoring method that provide a set authoring tools for specifying rules for combining sections of a first song to generate a second song. The set of authoring tools allow an array of cells to be arranged in first and second directions, and allow each body section to be associated with one set of cells that are arranged in the first direction and another set of cells that are arranged in the second direction. At each cell that belongs to one set of cells arranged in the first direction for a first body section and another set of cells arranged in the second direction for a second body section, the set of tools also allow the user to specify whether the second body section is allowed to follow the first body section. Some embodiments provide a method for compositing audio. The method receives (1) several song sections, and (2) for each particular song section, a priority value and a set of succession rules that identify a set of song sections that cannot follow the particular song section. Based on the priority values, the method adds the song sections to the first song until a desired first-song duration is reached without exceeding the duration or until all song sections have been examined for adding to the first song. The method then analyzes a sequence of song sections in the first song to remove any song section that violates a succession rule.

Audio authoring and compositing

Some embodiments provide an application that can automatically generate a movie from a collection of media clips stored on a device or accessible by the device. The movie creation process of some embodiments uses novel video and audio compositors that dynamically composite video and audio components of the movie. The video compositors process explores different combination of media clips and media-clip arrangements to produce an interesting video presentation. The audio compositor receives the duration of the video presentation, and dynamically generates a song for the video presentation based on this duration. Another novel interaction is that in some embodiments the audio compositor provides the starting location of its last segment to the video compositor so that the video compositor can align the start of the last video segment with this ending segment. In some embodiments, the video and audio compositors also synchronize fade-out effects that they apply to their respective presentations with each other. Also, in some embodiments, the video compositor can ask the audio compositor for one or more audio onsets that are near a particular time in the presentation. In some of these embodiments, the audio compositor returns (1) a list of onsets that are near a time that is specified by the video compositor, and (2) a priority for each of these onsets. The video compositor then uses this list of onsets to align an edit point in the composite video's definition to the location of one of the onsets based the specified priority value(s) and the desirability of the video edit at the onset location.

A method and apparatus for editing recorded sounds. The method and apparatus provides representations of audio clips. The method and apparatus provides a set of user interface tools for selecting a source audio clip and a target audio clip. The user interface tools determine a maximum voice volume of each clip. Based on the maximum voice volumes, the user interface tools adjust the volume of the target audio clip. The adjustment changes the maximum voice volume of the target audio clip to match the maximum voice volume of the first audio clip.
