Syntax
class FAutoCorrelationPitchDetector : public Audio::IPitchDetector
Remarks
Pitch detector based on autocorrelation. Note that autocorrelation pitch detectors give more accurate frequency results for low frequencies, but have issues with octave errors. Generally, it will produce erroneous frequency observations in octaves below the true pitch frequency.
