Abstract

Claims (32)

1 . A playback system for altering the frame rate of streaming digital movie data for synchronizing with an audio data recording to create a synchronized audiovisual work, the system comprising:

a processor;

a memory on a non-transitory computer readable medium that includes

a video display module on a non-transitory computer readable medium operable for displaying digital video at a variable rate;

an output module on a non-transitory computer readable medium operable for transmitting audio data to an output device;

a timing error module on a non-transitory computer readable medium operable for (i) determining a timing error between a time stamp and a next time stamp, (ii) adjusting the video presentation rate, and (iii) assessing the timing error periodically and adjusting the presentation rate so that the actual timing error is minimal and unnoticeable;

the playback system operable for creating and displaying the synchronized audiovisual work that includes

the audio data recording of an isolated audio track 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 digital movie data recording synchronized to the audio data recording; the digital movie 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 digital movie 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 digital movie data recording by the 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 the 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.

2 . The system of claim 1 , wherein the audio data of the isolated audio track comprises an originally recorded work.

3 . The system of claim 1 , wherein the audio data of the isolated audio track comprises a recreation of an originally recorded work.

4 . The system of claim 1 , wherein the work further includes instructions to use the tempo map for a looping of a selection of one or more bars to provide a repeated playback of a section of the audiovisual work.

5 . The system of claim 1 , further comprising a looping function to loop a particular section of the audiovisual work.

6 . The system of claim 1 , the video data including a looping notation display synchronized to a looping of a section of the audio data.

7 . The system of claim 1 including an animated graphical video display synchronized to the looping selection.

8 . The system of claim 7 , wherein the work includes a multi-track audio portion comprising an isolated audio track consisting of a solo performance.

9 . The system of claim 7 , wherein the work includes a plurality of recreated performances.

10 . The system of claim 1 , wherein the custom tempo map comprises an assignment of a transient in the isolated audio track having the fluctuation in tempos.

11 . The system of claim 1 , the audio data including vocals.

12 . The system of claim 1 , the audio data including a brass instrument.

13 . The system of claim 1 , the audio data including a woodwind instrument.

14 . The system of claim 1 , the audio data including a string instrument.

15 . The system of claim 1 , the audio data including a percussion instrument.

16 . The system of claim 1 , the work including a metronome track synchronized to the audio data.

17 . The system of claim 1 which further comprises a variable gain function that instructs the processor to vary a gain ratio in the audio data to selectively listen to one or more audio tracks.

18 . The system of claim 1 configured for use in streaming data through an internet network.
