Constructor & Destructor Documentation

◆ TempoTrackV2()

TempoTrackV2::TempoTrackV2 ( float  sampleRate,
size_t  dfIncrement 
)

Construct a tempo tracker that will operate on beat detection function data calculated from audio at the given sample rate with the given frame increment.

Currently the sample rate and increment are used only for the conversion from beat frame location to bpm in the tempo array.
