PitchYinProbabilities

streaming mode | Pitch category

Inputs

  • signal (vector_real) - the input signal frame

Outputs

  • pitch (vector_real) - the output pitch candidate frequencies in cents
  • probabilities (vector_real) - the output pitch candidate probabilities
  • RMS (real) - the output RMS value

Parameters

  • frameSize (integer ∈ [2, ∞), default = 2048) :
    number of samples in the input frame
  • lowAmp (real ∈ (0, 1], default = 0.1) :
    the low RMS amplitude threshold
  • preciseTime (bool ∈ {true, false}, default = false) :
    use non-standard precise YIN timing (slow).
  • sampleRate (real ∈ (0, ∞), default = 44100) :
    sampling rate of the input audio [Hz]

Description

This algorithm estimates the fundamental frequencies, their probabilities given the frame of a monophonic music signal. It is a part of the implementation of the probabilistic Yin algorithm [1].

An exception is thrown if an empty signal is provided.
