SuperFluxPeaks¶

Inputs¶

• novelty (real) - the input novelty

Outputs¶

• peaks (vector_real) - peaks instants [s]

Parameters¶

• combine (real ∈ (0, ∞), default = 30) :

  ms for onset combination

• 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.
