Abstract

Claims (48)

1. A system comprising:

an electronic device comprising audio processing circuitry, and pace tracking circuitry, wherein:

said pace tracking circuitry is operable to select, from a plurality of locally-stored songs and a plurality of network-accessible songs, one or more songs to be processed for playback by said audio processing circuitry;

said pace tracking circuitry is operable to control said selection based on a desired playback tempo of said one or more songs such that:

for said locally-stored songs, those of said locally-stored songs that have a natural tempo less than said desired tempo are eligible to be among said selected one or more songs; and

for said network-accessed songs, only those of said remotely-stored songs that have a natural tempo greater than said desired tempo are eligible to be among said selected one or more songs.

2. The system of claim 1 , comprising positioning circuitry operable to generate position data that indicates pace of a runner during a preceding, determined time interval.

3. The system of claim 1 , wherein:

said electronic device comprises memory, and:

said pace tracking circuitry is operable to control said song selection based on runner profile data stored in said memory.

4. The system of claim 3 , wherein said profile data comprises distance-per-stride data.

5. The system of claim 4 , wherein:

said electronic device comprises one or more sensors operable to function as a pedometer;

said electronic device comprises positioning circuitry operable to generate position data; and

said pace tracking circuitry is operable to update said distance-per-stride data based on said position data and based on data output by said one or more sensors.

6. The system of claim 1 , wherein:

said pace tracking circuitry is operable to control time stretching applied to songs processed for playback by said audio processing circuitry; and

said pace tracking circuitry is operable to control said time stretching based on position data generated by positioning circuitry of said electronic device.

7. The system of claim 6 , wherein said position data indicates pace of a runner during a preceding, determined time interval.

8. The system of claim 6 , wherein:

said electronic device comprises memory, and:

said pace tracking circuitry is operable to control said time stretching based on runner profile data stored in said memory.

9. The system of claim 8 , wherein said profile data comprises distance-per-stride data.

10. The system of claim 9 , wherein:

said electronic device comprises one or more sensors operable to function as a pedometer;

said electronic device comprises positioning circuitry operable to generate position data; and

said pace tracking circuitry is operable to update said distance-per-stride data based on said position data and based on data output by said one or more sensors.

11. A method comprising:

in an electronic device comprising audio processing circuitry, and pace tracking circuitry:

selecting, by said pace tracking circuitry, one or more songs to be processed for playback by said audio processing circuitry, wherein:

said selecting is based on desired playback tempo of said one or more songs;

said one or more songs are selected from among a plurality of locally-stored songs and a plurality of network-accessible songs;

for said locally-stored songs, those of said locally-stored songs that have a natural tempo less than said desired tempo are eligible to be among said selected one or more songs; and

for said network-accessed songs, only those of said remotely-stored songs that have a natural tempo greater than said desired tempo are eligible to be among said selected one or more songs.

12. The method of claim 11 , wherein said electronic device comprises positioning circuitry operable to generate position data that indicates pace of a runner during a preceding, determined time interval.

13. The method of claim 11 , wherein said electronic device comprises memory, and the method comprises:

said pace tracking circuitry controlling said song selection based on runner profile data stored in said memory.

14. The method of claim 13 , wherein said profile data comprises distance-per-stride data.

15. The method of claim 14 , wherein said electronic device comprises one or more sensors operable to function as a pedometer, and the method comprises:

said pace tracking circuitry updating said distance-per-stride data based on position data generated by positioning circuitry of said electronic device, and based on data output by said one or more sensors.

16. The method of claim 11 , comprising:

said pace tracking circuitry controlling time stretching applied to songs processed for playback by said audio processing circuitry based on position data generated by positioning circuitry of said electronic device.

17. The method of claim 16 , wherein said position data indicates pace of a runner during a preceding, determined time interval.

18. The method of claim 16 , wherein said electronic device comprises memory, and the method comprises:

said pace tracking circuitry controlling said time stretching based on runner profile data stored in said memory.

19. The method of claim 18 , wherein said profile data comprises distance-per-stride data.

20. The method of claim 19 , wherein said electronic device comprises one or more sensors operable to function as a pedometer and positioning circuitry operable to generate position data, and the method comprises:

said pace tracking circuitry updating said distance-per-stride data based on said position data and based on data output by said one or more sensors.
