Abstract

A system and methods for acquiring cadence and selecting a song version based on the acquired cadence are disclosed. If the system detects a new cadence, then a new song version that corresponds to the new cadence can be played. The new song version playback can start in a corresponding position as the location of playback in a currently-playing song version. Each related song version shares one or more characteristics, such as melody, but is different in at least one characteristic, such as tempo.

Claims

1. A method for transitioning between versions of a song, the method comprising:

during playback of a first version of the song, identifying a second version of the song from a plurality of pre-recorded song versions of the song;

determining a current chapter of the first version of the song;

determining a percentage of the current chapter that has been played;

determining a corresponding chapter of the second version of the song;

determining a corresponding percentage of the corresponding chapter of the second version of the song;

based on the corresponding percentage of the corresponding chapter, determining a playback position of the second version of the song; and

initiating playback of the second version of the song at the playback position of the second version of the song.

2. The method according to claim 1, further comprising determining a pitch change of the second version of the song.

3. The method according to claim 2, wherein determining the pitch change of the second version of the song includes determining a pitch change time, the pitch change time being a time period during which the pitch change is implemented.

4. The method according to claim 3, wherein the pitch change time is no less than 0.5 second and no greater than 5 seconds.

5. The method according to claim 3, wherein the pitch change time is no less than 1 second and no greater than 4 seconds.

6. The method according to claim 2, further comprising determining a pitch change of the first version of the song.

7. The method according to claim 1, wherein initiating playback of the second version of the song includes cross-fading the first version of the song and the second version of the song.

8. The method according to claim 7, wherein initiating playback of the second version of the song includes adjusting a tempo of the first version of the song.

9. The method according to claim 7, wherein initiating playback of the second version of the song includes adjusting a tempo of the second version of the song.

10. The method according to claim 7, further comprising, during the cross-fading, adjusting at least one of a first song version pitch and a second song version pitch.

11. A computer readable data storage device storing instructions that, when executed by at least one processing device, causes a media-playback device to:

during playback of a first version of a song, identify a second version of the song from a plurality of pre-recorded song versions of the song;

determine a current chapter of the first version of the song;

determine a percentage of the current chapter that has been played;

determine a corresponding chapter of the second version of the song;

determine a corresponding percentage of the corresponding chapter of the second version of the song;

based on the corresponding percentage of the corresponding chapter, determine a playback position of the second version of the song; and

initiate playback of the second version of the song at the playback position of the second version of the song.

12. The computer readable data storage device according to claim 11, further comprising instructions that, when executed by the at least one processing device, cause the media-playback device to:

determine a pitch change of the second version of the song.

13. The computer readable data storage device according to claim 12, wherein determining the pitch change of the second version of the song includes determining a pitch change time, the pitch change time being a time period during which the pitch change is implemented.

14. The computer readable data storage device according to claim 13, further comprising instructions that, when executed by the at least one processing device, cause the media-playback device to:

determine a pitch change of the first version of the song.

15. The computer readable data storage device according to claim 14, wherein initiating playback of the second version of the song includes cross-fading the first version of the song and the second version of the song.

16. The computer readable data storage device according to claim 15, wherein initiating playback of the second version of the song includes adjusting at least one of:

a first song version tempo and a second song version tempo.

17. The computer readable data storage device according to claim 16, wherein the pitch change time is no less than 0.5 second and no greater than 5 seconds.

18. A media server, comprising:

a database including;

at least one computer readable data storage device including a plurality of versions of a song, each of the plurality of versions of the song having a different tempo than each of the other plurality of versions of the song; and

at least one processing device,

wherein the at least one computer readable data storage device includes instructions stored thereon which, when executed by the at least one processing device, cause the media server to;

during playback of a first version of the song, identify a second version of the song from a plurality of pre-recorded song versions of the song;

determine a current chapter of the first version of the song;

determine a percentage of the current chapter that has been played;

determine a corresponding chapter of the second version of the song;

determine a corresponding percentage of the corresponding chapter of the second version of the song;

based on the corresponding percentage of the corresponding chapter, determine a playback position of the second version of the song; and

initiate playback of the second version of the song at the playback position of the second version of the song.

19. The media server according to claim 18, wherein the at least one computer readable data storage device further includes instructions stored thereon which, when executed by the at least one processing device, cause the media server to:

determine a pitch change of the first version of the song; and

determine a pitch change of the second version of the song, wherein determining the pitch change of the second version of the song includes determining a pitch change time, the pitch change time being a time period during which the pitch change is implemented.

20. The media server according to claim 19, wherein initiating playback of the second version of the song includes cross-fading the first version of the song and the second version of the song;

wherein initiating playback of the second version of the song includes adjusting at least one of;

a first song version tempo and a second song version tempo; and

wherein the pitch change time is no less than 1 second and no greater than 4 seconds.
