Pace-aware music player
An electronic device may comprise audio processing circuitry, pace tracking circuitry, and positioning circuitry. The pace tracking circuitry may be operable to selects a tempo of songs for playback, by the audio processing circuitry based on position data generated by the positioning circuitry, a desired tempo, and whether the songs are stored locally or network-accessible. The position data may indicate the pace of a runner during a preceding, determined time interval. The pace tracking circuitry may control the song selection and/or time stretching based on a runner profile data stored in memory of the music device. The profile data may include runner's distance-per-stride data. The electronic device may include sensors operable to function as a pedometer. The pace tracking circuitry may update the distance-per-stride data based on the position data and based on data output by the one or more sensors.
1. A non-transitory computer-readable medium (CRM) storing instructions that, when executed by a processor within an electronic device, cause the processor to:
receive a playback tempo and an audio source, wherein the audio source is a remote source or a memory within the electronic device;
select a song, from the audio source, with a tempo that is faster than the playback tempo, when the audio source is the remote source;
select a song, from the audio source, with a tempo that is faster than or slower than the playback tempo, when the audio source is the memory within the electronic device; and
adjust the tempo of the song according to the playback tempo.
2. The CRM of claim 1 , wherein the CRM stores instructions that cause the processor to:
receive position data; and
determine a pace a during a time interval.
3. The CRM of claim 2 , wherein CRM stores instructions that cause the processor to adjust the playback tempo according to a relative position.
4. The CRM of claim 3 , wherein CRM stores instructions that cause the processor to determine the relative position according to the pace.
5. The CRM of claim 1 , wherein the CRM stores instructions that cause the processor to access a profile in the memory.
6. The CRM of claim 5 , wherein the profile comprises the playback tempo.
7. The CRM of claim 5 , wherein the profile comprises a distance-per-stride measurement.
8. The CRM of claim 7 , wherein CRM stores instructions that cause the processor to update the distance-per-stride measurement according to a pedometer reading and a change in position.
9. The CRM of claim 7 , wherein CRM stores instructions that cause the processor to determine the change in position according to a GPS signal.
10. The CRM of claim 1 , wherein the remote source is accessible via a cellular service.
11. A method comprising:
performing via an electronic device:
receiving a playback tempo and an audio source, wherein the audio source is a remote source or a memory within the electronic device;
selecting a song, from the audio source, with a tempo that is faster than the playback tempo, when the audio source is the remote source;
selecting a song, from the audio source, with a tempo that is faster than or slower than the playback tempo, when the audio source is the memory within the electronic device; and
adjusting the tempo of the song according to the playback tempo.
12. The method of claim 11 , wherein the method comprises:
receiving position data; and
determining a pace a during a time interval.
13. The method of claim 12 , wherein method comprises adjusting the playback tempo according to a relative position.
14. The method of claim 13 , wherein method comprises determining the relative position according to the pace.
15. The method of claim 11 , wherein the method comprises accessing a profile in the memory.
16. The method of claim 15 , wherein the profile comprises the playback tempo.
17. The method of claim 15 , wherein the profile comprises a distance-per-stride measurement.
18. The method of claim 17 , wherein method comprises updating the distance-per-stride measurement according to a pedometer reading and a change in position.
19. The method of claim 17 , wherein method comprises determining the change in position according to a GPS signal.
20. The method of claim 11 , wherein the remote source is accessible via a cellular service.
