BeatDetector

The BeatDetector analyzer looks for spikes in the energy of an audio signal which are often associated with rhythmic musical beats and can be used to trigger a response whenever the incoming audio signal pulses. Note that this implementation does not return a tempo or BPM (beats per minute) value \u2014 it can only tell you whether the current moment of audio contains a beat or not.
