1. A music playout method, comprising the steps of:
- (a) detecting information from a user, said information selected from the group consisting of biometric information, performance information, and combinations thereof;
(b) computing a difference between said information and a target;
(c) adjusting the tempo of music being played out for said user, said adjusting in response to the results of said computing a difference; and
(d) repeating steps (a)-(c).

Abstract
Beat detection in audio streams for various applications: (i) to encourage desired athletic parameters, such as target or current heart rate, during training or workout by adjusting tempo of accompanying music; (ii) to monitor operating conditions of mechanical devices which inherently include vibrations; (iii) to synchronize audio play-out beat rate to mechanical device beat rate.

7. A playout system, comprising:
-
(a) an input for real-time information from a user, said information selected from the group consisting of biometric information, performance information, and combinations thereof;
(b) a source for an audio signal;
(c) an audio player, said audio player coupled to said source and to said input, wherein said audio player controls the tempo of an audio signal from said source for playout for said user, where said control is in response to a difference between said real-time information and a target. - View Dependent Claims (8, 9)

14. A method of audio playout, comprising the steps of:
-
(a) providing an audio playout device which includes a beat matcher;
(b) providing beat information corresponding to a mechanical device plus worker speed metric/desired pace information for a worker associated with said mechanical device;
(c) computing a target beat rate from said beat information plus said worker speed metric/desired pace information; and
(d) playing out an audio input for said worker wherein said playing out includes beat matching said audio input to said target beat rate.

15. An audio playout system, comprising:
-
(a) a first input for beat information corresponding to a mechanical device;
(b) a second input for worker speed metric/desired pace information for a worker associated with said mechanical device;
(c) a playout device coupled to said first and second inputs, wherein said playout device includes a beat matcher for playing out an audio input for said worker and at a target beat rate where said target beat rate is computed from said beat information plus said worker speed metric/desired pace information.
