Methods and apparatus provide for a clip-beat aligner that identifies musical beats in an audio file. An editing mode is provided to associate the audio file with a media segment according to a timeline. The clip-beat aligner aligns a boundary of the media segment with a musical beat on the timeline. Upon performing an editing operation, the clip-beat aligner maintains that the boundary of the media segment is aligned with any one of the musical beats. To align a boundary of each media segment with a musical beat, the clip-beat aligner identifies a musical beat that is proximate to the position of the media segment's boundary. The clip-beat aligner then aligns the media segment's boundary with the proximate musical beat by, if necessary, automatically trimming the media segment's duration such that the media segment's boundary occurs at the same moment in time as the proximate musical beat.
