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.

Abstract: A computer implemented method of multi-threaded data processing operation partitions each data processing module into at least five sub-modules including (1) receiving messages, (2) processing received messages, (3) getting resources for module function, (4) performing a core data processing operation of the module and (5) outputting resources generated. These modules are launched and retired as needed in a multi-threaded environment. A framework includes APIs for the module and each sub-module. The message and data handling sub-modules are optionally shared among modules.
