Analyses a given range of the loaded sound in order to identify and store beats positions. In this case beats positions detection is performed offline, i.e. while the sound is not being played: if you should need detecting beats positions in real-time during playback, use the BeatsDetectEnableRT method.
Parameters for beats positions analysis can be obtained/set through the BeatsDetectGetParams and BeatsDetectSetParams methods and the range of sound to analyze can be set through the BeatsDetectSetRange method.
Once beats positions have been calculated, the container application will be notified through the BeatsAvailableOffline event.
For further details about beats detection refer to the How to detect beats positions and BPM tutorial.
