5. The audio pacing device as claimed in claim 2 , wherein the sensing unit is a heart rate monitor.
6. The audio pacing device as claimed in claim 3 , wherein the sensing unit is a step-speed measurement unit.
7. The audio pacing device as claimed in claim 1 , wherein the sensing unit and the processing unit are connected in a wired or wireless way.
8. The audio pacing device as claimed in claim 1 , wherein the predetermined reference value includes reference values selected by a user or a programmed exercise routine.
9. The audio pacing device as claimed in claim 1 , wherein the audio signals are encoded in an MP3, WAV, MPEG-4, WMA, or AAC format.
10. The audio pacing device as claimed in claim 1 , further including a switch to enable use of the audio pacing device in a first mode having a first sensing unit and a first parameter and a second mode having second sensing unit and a second parameter.
11. The audio pacing device as claimed in claim 1 , wherein if, after the processing unit adjusts the tempo of the selected audio signal up to the predetermined percentage of the predetermined tempo value, the processing unit determines that the intensity of the parameter of the user should be increased or decreased further, then the processing unit selects a different audio signal.
12. An audio pacing method, comprising the steps of:
receiving a parameter of a user in physical exercise from a sensing unit;
determining whether intensity of the parameter of the user should be increased, decreased or maintained by using the parameter of the user from the sensing unit and a predetermined reference value;
selecting an audio signal, from a plurality of audio signals that have predetermined tempo values, having a tempo that encourages the user to increase, decrease or maintain the intensity, further comprising the step of adjusting the tempo of a selected audio signal up to a predetermined percentage of the tempo;
calculating, by an audio pacing device, the predetermined tempo values of the plurality of audio signals; and
categorizing the plurality of audio signals based on their predetermined tempo values.
13. The audio pacing method as claimed in claim 12 , further comprising the step of a user selecting the said predetermined reference value from a group of reference values or a programmed exercise routine.
14. The heart rate audio pacing method as claimed in claim 12 , wherein the audio signals are encoded in an MP3, WAV, MPEG-4, WMA, or AAC format.
