Abstract
The teachings described herein are generally directed to a system, method, and apparatus for separating and mixing tracks within music. The system can have a video that is synchronized with the variations in the musical tempo through a variable timing reference track designed and provided for a user of the preselected performance that was prerecorded, wherein the designing of the variable timing reference track includes creating a tempo map having variable tempos, rhythms, and beats using notes from the preselected performance.
Claims16
A synchronized audiovisual work, the work comprising:
- an audio data recording of an isolated audio track in a preselected piece of music having (i) a plurality of audio tracks, the audio data recording having variable tempos, rhythms, and beats;
- the audio data recording having an array of audio time samples that include (ii) an audio synchronization start time;
- (iii) an audio synchronization stop time;
- and, (iv) an audio duration in the array of audio time samples;
- a custom tempo map that is configured (i) to correspond with the variable tempos, rhythms, and beats of the audio data recording, and (ii) to include a mapping of the space between musical notes in the isolated audio track to determine the beats per minute of each bar of music in the isolated audio track for the preselected piece of music;
- and,
- a video data recording synchronized to the audio data recording;
- the video data recording having array of video time samples that include (ii) a video synchronization start time;
- (iii) a video synchronization stop time;
- and, (iv) an audio duration in the array of audio time samples;
- the video synchronization start time coincident in time with the audio synchronization start time, the video synchronization stop time coincident in time with the audio synchronization stop time, and the array of video time samples synchronized with the array of audio time samples for the duration of each using the custom tempo map to configure the synchronized audiovisual work;
- wherein,
- the audio data recording, the video data recording, and the custom tempo map are each stored on a non-transitory computer readable medium
- the audio data recording is synchronized to the video data recording by a processor with instructions for aligning the array of audio time samples with the array of video time samples, the synchronizing including
- assessing the synchronization of a video time sample in the array of video time samples to a corresponding audio time sample in the array of audio time samples to determine a timing error between the video time sample and the audio time sample using the custom tempo map;
- and,
- adjusting a video presentation rate measured between the video time sample and the next video time sample in the array of video time samples, such that the timing error is unnoticeable.
