Abstract: 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.
