SuperFluxPeaks

standard mode | Rhythm category

Inputs

  • novelty (vector_real) - the input onset detection function

Outputs

  • peaks (vector_real) - detected peaks' instants [s]

Parameters

  • combine (real ∈ (0, ∞), default = 30) :
    time threshold for double onsets detections (ms)
  • frameRate (real ∈ (0, ∞), default = 172) :
    frameRate
  • pre_avg (real ∈ (0, ∞), default = 100) :
    look back duration for moving average filter [ms]
  • pre_max (real ∈ (0, ∞), default = 30) :
    look back duration for moving maximum filter [ms]
  • ratioThreshold (real ∈ [0, ∞), default = 16) :
    ratio threshold for peak picking with respect to novelty_signal/novelty_average rate, use 0 to disable it (for low-energy onsets)
  • threshold (real ∈ [0, ∞), default = 0.05) :
    threshold for peak peaking with respect to the difference between novelty_signal and average_signal (for onsets in ambient noise)

Description

This algorithm detects peaks of an onset detection function computed by the SuperFluxNovelty algorithm. See SuperFluxExtractor for more details.
