Method and apparatus for producing audio tracks
First Claim
1. A system for use with a video timing specification defining multiple video events where each such video event occurs at a unique timing point relative to a start time, said system being operable to produce an audio track including music events synchronized with said video events, said system comprising:
- a music library comprising a plurality of music sources each having a plurality of defined length data blocks associated therewith;
a user controller operable to select a music source;
a timing controller responsive to said timing specification for identifying successive timing segments, each timing segment having a duration delimited by successive video events;
a music segment generator operable to produce an untrimmed music segment for each timing segment, each untrimmed music segment being comprised of a sequence of one or more data blocks selected from said selected music source; and
a music segment trimmer operable to adjust the defined length of said untrimmed music segments to produce a plurality of final music segments each having a duration substantially equal to the duration of a corresponding timing segment; and
whereinsaid timing controller operates to assemble said plurality of final music segments in an ordered sequence to define music events synchronized with said video events.

Abstract
A system for automatically manipulating prerecorded audio data to produce an audio track synchronized to a target video track. The system allows a user to select a music source from multiple music sources stored in a music library. Each music source includes multiple audio portions having block data and beat data associated therewith. The block data includes data blocks respectively, specifying the duration of the associated audio portions. Each data block preferably also includes interblock compatibility data and/or suitability data. The beat data, generally referred to as a “beatmap”, comprises timing information specifying the rhythmic pulse, or “beat” for the associated music source portion. The system is operable to produce an audio track synchronized to a video timing specification (VTS) specifying successive timing segments delimited by successive video events. After the user selects a music source, the system generates a music segment for each defined timing segment. Each music segment is generated by assembling an ordered sequence of compatible data blocks selected at least in part based on their suitability and/or compatibility characteristics.

7. A method for generating an audio track to accompany a video track comprised of an ordered sequence of video events, said method comprising:
-
providing a plurality of music sources where each source includes multiple portions and a data block for each such portion specifying its duration; identifying a sequence of discrete timing segments where each such timing segment is delimited by successive video events; generating for each timing segment an untrimmed music segment comprised of an ordered sequence of one or more selected data blocks; comparing the duration of the data block sequence for each untrimmed music segment with the duration of the associated timing segment; processing each untrimmed music segment to produce a final music segment having a data block sequence defining a duration matching the duration of its associated timing segment; and assembling a plurality of final music segments in an ordered sequence to produce said audio track of successive music events synchronized to said successive video events. - View Dependent Claims (8, 9, 10, 11)
